Best Metal Cutting Circular Saw Reviews and Buying Guide

Best Metal Cutting Circular Saw Reviews and Buying Guide

Here at Miter Saw Judge, we recently looked at a selection of the finest metal cutting chop saws. We’ll continue that theme today by pivoting into the best circular saws designed with metalwork in mind.

As the name makes abundantly clear, these saws have a circular blade that revolves at high velocity and is tough enough to slice through metal.

Now, we’ll point out that it is perfectly possible to use a regular circular saw using a 7 ¼-inch metal cutting blade. Many manufacturers offer these and to some extent they’re fine with certain metals. If you invest in a dedicated metal cutting model, though, you’ll enjoy greater scope with one intended for the purpose.

Metal cutting circs work in pretty much the same manner as a regular variant with a small but crucial difference…

A model expressly designed to cut metal will run at much lower speeds. While a wood circular saw runs at up to 5000 RPM, one intended for metalwork will usually max out at 3900 RPM or below. By using higher speeds on metal, you risk burning out the motor and damaging the blade.

So…

Our advice is that if you’re looking to cut through metal on a regular basis, it’s well worth considering a specially designed circular saw as an investment rather than an expense.

Before we get going with our breakdown of the strongest options at your disposal, a brief glance at the 2 main types of blade you can choose from…

Carbide-Tipped Blades

With carbide-tipped blades, you’ll enjoy increased lifespan while also generating cleaner cuts. You won’t suffer from too many sparks being kicked up and the finish will be clean and smooth.

Abrasive Discs

An abrasive disc is cheaper but it wears down as you use it and won’t last the distance. The most serious drawback with this type of blade, though, is the shower of sparks in your workshop so these are really not recommended for most applications.

Best Metal Cutting Circular Saw Reviews and Buying Guide

Our opener in this curated list of the finest metal cutting circular saw is the enduringly popular 4131 from industry legend Makita.

Suitable for both the home shop and the jobsite, you need to dig a little deeper for the Makita than some of the competition but what do you get for your money? We’ll break that down with our impartial review after a quick pitstop by the main features.

What did we do without it. We manufacture and install metal fences, we once cut posts with a cutting torch then ground smooth.With this little jewel we cut the post and we are finished. One of our better investments.

By Amazon Customer

Main Features

  • 13-amp motor
  • 3500 RPM
  • 2 ½-inch maximum depth of cut
  • 10 ½ pounds
  • Tool-less blade cover

If you’re wielding any power tools for extended periods of time, weight is a crucial factor. Despite loading this saw with tech, it weighs less than 11 pounds so you’ll be able to comfortably work away for hours without feeling fatigued.

The highly capable 13-amp power plant kicks out more than enough grunt for dealing with a wide array of metals. You’ll get the requisite low-speed 3500 RPM to carry out this work safely, too. You’ll be able to cut through conduit, steel roofing and iron pipe without the blade heating up even after extended cutting sessions.

Power alone is futile if the cuts are not clean and accurate. With the Makita, your workpiece will be finished crisply and cleanly with no burrs and no spark shower kicked up while you’re cutting either. There’s a rugged blade cover which you can remove tool-free and the chip collection is pretty effective, too. If you want a spotless workshop without being menaced by sparks, the Makita makes that possible.

The blades come with CERMET tips. This is an innovative mixture of ceramic and metal that’s remarkably heat-resistant. Not only will the blade not heat up in use, they’ll last longer into the bargain. The spindle lock keeps the blade in place.

Depth of cut is generous at 2 ½ inches. This depth is ideal for metal roofing projects and metal studs.

Build quality is superb throughout. From the stainless steel base through to that pioneering CERMET-tipped blade, you might pay for the privilege but you’ll get a saw that’s built to last.

Along with a 1-year warranty, you’ll also get some safety goggle thrown in so you can keep your eyes protected without needing to head to the hardware store first.

Before we tail off with our verdict, take a look at our summary of the principal pros and cons of the Makita 4131 so you can see at a glance if it meshes with your metal cutting needs…

Pro's

  • Remarkably lightweight at just over 10 ½ pounds so perfect if you work for sustained periods
  • You can put this saw through some pretty serious punishment without the blade heating up
  • Clean and highly precise cuts that will leave the metal smooth and burr-free
  • Robust blade cover offers maximum protection against chips flying
  • Heat-resistant ceramic-metal mixture of CERMET-tipped blades cut through even challenging materials with ease
  • Plunge cutting is a cinch with this circular saw
  • The stainless steel base gives you a great deal of stability and durability without weighing the saw down
  • 2 ½-inch depth of cut perfect for studwork and metal roofing so works just as well out on the jobsite as in the home workshop

Con's

  • Reasonably expensive but still represents solid overall value for money considering the hard-hitting performance
  • Block guard makes it slightly awkward to see where you’re going

Conclusion

The Makita 4131 is an extremely versatile powerhouse from a brand you can trust. While you can get away with pressing a regular circular saw into commission with a metal cutting blade, you’re far better off investing in a special unit like this whether you’re looking to carry out some metalworking in the home workshop or out on site.

The lightweight nature of the saw combined with all the power you need to scythe through hard and demanding materials means you’ll get everything you need for most reasonable needs. While the Makita is certainly not the cheapest metal cutting circular saw, it is among the very best.

If you’ve got a fluid budget and exacting tastes, check out the 4131 at your earliest convenience. You’ll be rewarded with saw that delivers power and precision in one lightweight and maneuverable package.

Cordless power tools are not to everyone’s liking so if the idea of a cable-free circ doesn’t appeal, scroll down to the Makita below. If, on the other hand, you appreciate the many benefits brought about by a cord-free model, the Bosch is well worth popping on your shortlist.

The major drawback with most cordless tools is a significant drop in power but you certainly won’t feel like you’re dipping out with the CSM180B. Check out the principal features before we explore this light but highly capable metal cutting circular saw in more depth…

  • Bare Tool
  • Lithium-Ion
  • by Bosch

Beyond my expectations! Cuts thru metal like butter. Precise and clean cuts. The saw lasts almost forever!

By Amazon Customer

Main Features

  • 18-volt lithium-ion battery
  • 3800 RPM
  • Four-pole ferrite motor
  • 2-inch cutting capacity
  • 4 1/3 pounds

The first thing you’ll notice about this metal cutting saw when you pick it up is the super-light and balanced feel. Weighing less than 5 pounds even with the battery in place, you’ll be able to undertake lengthy and ambitious projects without feeling like you’re carrying a lead weight.

While many cordless power tools can leave you distinctly underwhelmed in terms of performance, the powerplant on the Bosch is impressive. The four-pole ferrite motor was designed expressly to slice through a range of metals out on the jobsite and it’s here that cordless convenience comes into its own. You won’t need to be tethered to a power outlet and you won’t be menaced by trailing extension cords either. In return, you won’t find yourself let down even when you’re working with challenging materials.

Ideal for electrical plumbing, metal framing, pipefitting or working on HVAC systems, any time you need to deal with cutting metal in a tight space, the Bosch will deliver.

Spinning the blade at 3800 RPM, you’ll get the low speed you need to work safely with metal while preserving blade life into the bargain.

Despite the grunt behind it, the Bosch has a slimline and lightweight form factor. Measuring up at just 14 x 7 inches and weighing less than 6 pounds, you’ll be able to keep going for hours without feeling in any way encumbered.

Don’t think for a minute that lightweight nature translates to a weak build, though. From the steel footplate right on through, you’ll get a rugged circular saw built to withstand plenty of punishment.

A cut line guide you can easily see through the see-through window helps keep accuracy uppermost and you’ll be able to slice your way through 2-inch material at 90 degrees without meeting much by the way of resistance. Cuts are not just quick but remarkably clean, too.

If you’re not happy with the stock blade – and, let’s face it, they often fail to deliver – the Bosch offers robust third-party support. This is a nice touch and doesn’t lock you in to a set of blades that might not suit. Swapping the blade out is a breeze with the hex you need bundled and onboard storage ensuring it’s always close at hand when you need it.

Register your tool with Bosch and you’ll benefit from a 3-year protection plan, battery replacement during the first 2 years after purchase and a resolution hotline where the manufacturer aims to solve all problem with a single call. You can’t ask for much more than that at this price-point.

Pro's

  • Specialty four-pole ferrite motor tailor-made for a wide range of metal cutting applications serving up unrivalled performance
  • Steel foot plate built to last and offering easily adjustable cutting depth
  • You can power through metal up to 2 inches at 90 degrees with this potent circular saw
  • As with any cordless tool, you’ll enjoy complete freedom of movement simply not possible with a corded counterpart
  • Cutting visibility enhanced thanks to transparent viewing window
  • If you’re already invested into the Bosch lithium-ion range, you can save money with the bare tool and use your existing battery and charger
  • Impeccable balance overcoming the top-heavy feel that mars many circular saws
  • Compact footprint and lightweight build allows you to work for long periods without feeling tired

Con's

  • Works out much more expensive if you don’t already own the battery and charger so make sure you factor this into budgeting
  • You’ll struggle to cut all the way through a door in a single pass without making the motor labor and struggle

Conclusion

If you’re already invested into the Bosch ecosystem of cordless tools, you can save money by picking up the bare tool and using your existing battery and charger. Priced very competitively, this is a saw perfect for anyone on a tighter budget who isn’t prepared to compromise build quality or performance in pursuit of a bargain.

For anyone who’s not a fan of cordless saws, this is obviously not the model for you. We’re not here to change your mind about that or to push you toward an unsuitable product. Buying power tools is highly personal so think about your requirements closely. If you fancy all the convenience afforded by a cord-free saw and you want to buy into a brand you can trust at a reasonable price-point, we can’t recommend this powerful yet precise metal cutting circular saw from Bosch strongly enough.

While the MK Morse metal cutting circular saw still allows you to work with softer materials, if you’re looking to undertake some ambitious metalworking projects, you’ll be in safe hands.

With a range of sizings available from 7 inches through to the 14-inch line-topping beast, there’s a model for all needs so which one makes the best fit for you? We’ll be investigating the scaled-down 7-incher today so, before we explore this saw in more detail, a quick glimpse at the core features…

  • 7-Inch
  • 10+ Reviews
  • by MK Morse

Love this saw & their blades as well. We cut 14″ , 12 GA steel stud joists effortlessly, since a 14″ chopsaw is too small to do in 1 cut. This MK Morse 7″ is a champ.

By Amazon Customer

Main Features

  • 11-amp motor
  • 3500 RPM
  • Retractable blade guard
  • Chip collection cover
  • Spindle lock

MK Morse market their saws quite heavily. In this classic video, they show the circular saw scything a car in half. We’ll presume you don’t have any projects that ambitious in your home workshop but, whether you’re a mechanic or an electrician or simply a hobbyist looking to work with tougher materials, this saw is a highly capable all-rounder.

If you opt for the smaller 7-inch model, you’ll get exceptional firepower despite the saw weighing a mere 13 pounds. This allows you to work with challenging applications for lengthy spells without feeling burdened or fatigued. You’ll be able to deal with a broad spread of applications from pipe and angle iron to channel iron and steel plate. Capable of cutting through other ferrous metals, too, there’s little this saw – codenamed the Metal Devil – doesn’t take neatly and confidently in its stride.

As well as that lightweight form factor, ergonomics are uppermost throughout. The comfy grips are designed so there’s almost no chance of slippage and you’ll be able to beaver away for hours without your hands feeling clawed up. Corded, the 7-foot cable could be cut slightly longer but still gives you sufficient room for maneuver in most workshops.

Powered by an 11-amp unit that’s extremely torque, you’ll get a maximum no-load speed of 3500 RPM tailor-made for working with metal. You’ll get crisp and smooth cuts every time without a cascade of sparks menacing you. Reach extends to 2 3/8 inches with a ¼-inch depth of cut with mild steel.

With blade alignment guides and the sight opening making positioning a cinch, you can dramatically reduce wastage while saving some precious time into the bargain.

The retention chamber copes admirably collecting metal chips when you’re working away and it also serves to dampen the noise that can be problematic when you’re undertaking any metalworking project.

The blade that comes bundled has a retractable guard for your safety. Swapping the stock blade is super-simple and the hex key required is thrown in. Our own advice is to consider experimenting with other blades since the one included generates mixed press. It all depends on what you’re cutting and personal preference.

With safety glasses, ear plugs and a carrying case packaged, you’re spoiled considering the bargain-basement price of this classic MK Morse.

You benefit from an overload switch but there’s no brake or quick release on the spindle. Neither of these could be considered deal-breakers, especially when you take pricing into account.

Before we deliver out verdict, we’ll highlight the leading advantages and drawbacks of this potent metal cutting circular saw.

Pro's

  • This saw comes in 3 configurations (7-inch, 9-inch and 14-inch) so you can buy in line with the type of projects you’ll be dealing with most
  • Cutting reach is an impressive 2 3/8 inches with depth of cut extending to 1.4-inch when working with mild steel
  • Powerful 11-amp motor is remarkably torque and spins the blade at 3500 RPM giving you the finesse you need for metalwork
  • Bevel cut from 0 degrees out to 45 degrees
  • There’s a chip retention chamber with pretty much all debris safely contained
  • The guide arrows and site opening simplify positioning the saw and you’ll also cut right down on wastage
  • Tipping the scales at just 13 pounds, you can work for sustained periods without feeling fatigued
  • Sure grip handles help further if you’re working for extended spells and also increase the amount of control you’ll have over the saw even when working with challenging materials

Con's

  • You won’t benefit from a brake which is a mild disappointment
  • Some users have experienced the blade heating up to some extent

Conclusion

When you’re looking for a circular saw that will allow you to work with ease across a wide number of metal applications while combining power and precision, MK Morse is a safe bet.

If the 7-inch model doesn’t offer you quite enough oomph, you can step things up to one of the larger saws for a nominal charge. 

With a reasonable depth of a cut and a great deal of flexibility, this is one of our personal favorites that we can’t recommend strongly enough. A significant body of positive user opinion aligns with our verdict so why not road test this powerful but understated beast?

The first thing we’ll point out about the Milwaukee 6370 is that it’s certainly no lightweight. Weighing in at 14 pounds, you’ll get a powerful 8-inch beast to compensate for that extra poundage.

While this saw doesn’t make the best choice if you have some modest tinkering to do in a small home workshop, if you’re planning to undertake heavier-duty commercial projects or some really ambitious metalworking, it’s well worth investing in this powerhouse from Milwaukee.

Decent saw, good power, but the shoe is appx 1/2 mm out of square with the blade, back to front. As a previous review I saw mentioned, this means that trying to saw along a straight edge ends up with the saw binding against the straight edge. For me, it bound up at about inch 11 on a 12 inch cut. Also, I have seen a number of reviews stating that the front saw-to-shoe mount is easy to break. From looking at the tiny spot welds that hold it on, I can easily believe that this will be a point of failure in the future. I’ll probably end up drilling out those welds and redoing them to both square the blade and reinforce the mount. For the price, this should not be necessary.

By Amazon Customer

Before we outline fully where this metal cutting saw stands and falls, a brief summary of the leading features…

Main Features

  • 13-amp motor
  • 3700 RPM
  • 8-inch dry cutting blade
  • 90-degree cutting depth
  • On-board sight line

Perhaps the key selling point of the 6370 is the innovative dry cutting technology. This brings about several benefits. Firstly, you’ll dramatically reduce the volume of sparks created even when you’re working with demanding materials. Any that are kicked up should be safely contained by the onboard chip collector. You’ll also be able to handle the metal almost as soon as you’ve finished cutting it, a valuable time-saver if you’re carrying out lots of repeatable work.

Cuts are clean and smooth with a 13-amp motor driving proceedings. You’ll get the low-ish speed of 3700 RPM perfect for working with metal and here your choices are diverse. From 10-gauge sheets to ¼-inch steel plate, you’ll find the 8-inch blade makes light work of most metal it encounters.

The CERMET tips of the blade are designed not to wear down and they’ll deliver fast and precise cuts while staying sharp for much longer than you’d expect. If you exercise proper technique, you can even make your way through ¾-inch steel plate but we wouldn’t recommend this unless you’re a skilled practitioner.

The rugged magnesium blade shield contains the cool waste neatly and this is driven down into the chip tank onboard. You’ll find your workshop stays remarkably clean even when you’re dealing with pretty hardcore metalworking.

Unlike the majority of corded metal cutting saws, the 6370 comes equipped with a lower guard retraction lever. It’s small extra touches like this that go some way toward justifying the stiffer price tag.

You’ll be able to execute plunge cuts seamlessly by hitting the lever so, again, you won’t waste precious time if you’re working to tight deadlines.

Check out a breakdown of the main advantages and the couple of minor drawbacks so you can establish whether the Milwaukee 6370 makes sense for you…

Pro's

  • Hit the lever and make plunge cuts with consummate ease
  • Nimble and potent 13-amp motor gives you the ability to cut through ¼-inch steel plate and 10-gauge sheets with little by the way of resistance
  • Dry cutting technology shears the waste to produce clean and smooth cuts with almost no sparks kicked up
  • CERMET-tipped 8-inch blade gives you a great deal of scope and the blade cuts faster while staying sharp for longer
  • Cool cutting means you can handle the workpiece almost immediately cutting down on accidents as well as wasted time
  • Integrated chip tank keeps your workshop clean, safe and debris-free
  • Lower guard retraction lever which you don’t normally see on corded metal cutting saws
  • Quick release blade shield latch along with blade point-of-entry indicators and a sight line complete a winning package from Milwaukee

Con's

  • Not the lightest saw weighing fully 14 pounds
  • Fairly expensive compared to some of the competition

Conclusion

The Milwaukee 6370 is certainly not a circular saw for everyone. If you’re a casual hobbyist looking to cut a few pieces of metal from time to time, it would be complete overkill. Also, if you’re hunting for a lightweight and highly maneuverable circular saw, the 6370 is unsuitable.

If, on the other hand, you’re looking to engage in some demanding projects where you need power married to precision and you need a saw that will help boost productivity without compromising the finish, the 6370 is an absolute must. While it’s not particularly cheap, you should consider adding a saw like this to your arsenal as an investment rather than an expense. Once you start churning your way through metal, you’ll appreciate what a return on that investment the Milwaukee will generate.

Evolution Power Tools are stealthily widening their range and this entry-level model, the 180HD, packs a 7 ¼ blade capable of dealing with a broad spread of materials. You’ll also be able to work with wood so it’s a versatile addition to your workshop.

 

While not the lightest circular saw up for grabs, you’ll appreciate the balanced feel and the overall performance that makes it worth those few extra pounds. 

Check out the core features before we highlight where this metal cutting circ stands and where it might let you down…

  • 7-1/4" Inch
  • 200+ Reviews
  • by EPT

It’s an amazing saw. It cuts great. The base is lacking a method of mounting it to a saw table / base. It would be beneficial if there were an indication on the saw platform that shows the minimum cut allowed for a 90 degree up to a 45 degree cut. Although the instructions mention a minimum cut of 5/16″ there is no reference to what angle of cut that applies to. I learned the hard way when trying to make a miter cut through 3/4″ inch square stock. ( see photos, the arrows indicate where the mitered cut off piece got lodged inside between the blade and guard. 

Main Features

  • 9-amp motor
  • Adjustable cutting depth
  • 0 to 45-degree bevel tilt
  • Cut capacity at 90 degrees: 2 ¼ inches
  • Bevel cut capacity at 45 degrees 1 3/8 inches

The 9-amp motor might not kick out quite as much power as some of the competition but it’s still more than fit for purpose. Raw power unchecked is not your primary goal when you’re working with sheets of metal and the Evolution serves up the precision you’re really seeking.

From square tube to round pipe, steel plate to sheet metals, you’ll get a great deal of flexibility in this pocket-friendly circular saw. While it might not be man enough to endure unbroken use in heavy industrial settings, it’s certainly more than capable of doing a stint out on the jobsite.

With a high-torque gearbox and impeccable 40-tooth blades with carbide tips, you’ll enjoy extended lifespan of both motor and blades. You can expect blade life outflanking abrasives by a factor of 20.

As with all cool-cutting blades, you’ll be able to handle the material directly after cutting. You’ll get no unsightly burrs to mar the finish and you won’t find yourself deluged by sparks either.

Despite coming in at such a reasonable price-point, you’ll be covered by a generous 3-year manufacturer’s warranty removing any trepidation from purchase.

Take a quick look at a curated list of the main pros and cons before we round out with our verdict and push on with the buying guide…

Pro's

  • Enjoy the versatility of cutting through wood and a variety of metals, too
  • Ideal for beginners due to its user-friendly nature and ergonomics
  • 9-amp motor delivers plenty of torque perfect for a range of applications
  • While the stock blade is designed to cut through stainless steel and aluminum, you’ll also be able to slip in a blade suited for woodworking making this a multi-purpose investment
  • Bevel tilt further enhances the adaptability of this potent circular saw
  • Blade cuts much cooler than abrasives and you’ll able to handle the workpiece almost directly after the cut has been executed
  • Depth adjustment lever allows you to fine-tune depth of cut, a great touch if you’re working with sheet metals
  • Blade is not just highly effective but remarkably durable, too

Con's

  • Not the lightest tool in the box at 13 pounds
  • Not the best choice for use out on the jobsite despite being marketed as an industrial saw

Conclusion

If you steer away from the bold claims made by Evolution that this is a dedicated industrial circular saw, you should still be pleasantly surprised with the performance. This is doubly impressive when you factor in the pricing, almost budget territory without forcing any meaningful sacrifices on you.

For anyone just starting out with metalworking or those looking to work with metal from time to time while predominantly focusing on woodwork, this innovative saw lets you tackle both areas with equal ease. Simply invest in another blade or two and widen your repertoire.

If you’re prepared to veer away from the usual roster of brands that dominate power tools, Evolution is well worth your investigation and this agile little 7 ¼-inch circular saw is a low-key winner.

Who Needs Metal Cutting Circular Saws?

Whether you’re an electrician or a mechanic or you just fancy deviating from woodworking to try your hand at cutting some metal, if you’re planning to work with any type of metal on a regular basis, it pays to invest in a dedicated circular saw.

As we outlined above, trying to pop a metal cutting blade into a traditional wood cutting circular saw is unwise. The blade is likely to spin far too quickly and you won’t end up with the results you’re looking for. As you’ll see in the FAQs, you will be able to pop a wood cutting blade in a metal cutting saw so if you opt for something like the Evolution 180HD above, you’ll get the best of both worlds.

Buying Guide

Hunting for the best metal cutting circular saw can initially seem overwhelming.

Once you start analyzing what you need from the saw, though, you’ll see it’s really not so complex after all. This needs analysis is perhaps the most crucial part of any buying decision with power tools so don’t be tempted to just rush in. 

Think about the type of metals you need to cut and the scope of work you’ll be carrying out so this can guide your decision. You don’t need a pro-grade saw if you’re tinkering around in the home workshop. Equally, it’s senseless to be a saw fit for hobbyists if you’ve got plans to use your circular saw extensively out on the job site.

When it comes to price, don’t forget to focus on overall value rather than simply obsessing over the bottom line.

Here at Miter Saw Judge, we’re here to save you time and money so we’ll launch in now with our concise buying guide to make your life easier every step of the way…

What to Consider When Buying a Metal Cutting Circular Saw

Weight

Even though the majority of the cuts you’ll be making with your circular saw will be horizontal, it’s still likely you’ll be working overhead from time to time.

 

Also, even when you’re making horizontal cuts, the weight of the saw is relevant if you’ll be working for prolonged periods.

There’s no right or wrong answer to what makes the right weight. As with all aspects of your purchase, you need to focus on what feels comfortable for you and to make sure you don’t put yourself out of your comfort zone.

The lightest saw we look at today weighs less than 6 pounds while the bulkiest is fully 14 pounds. You’ve got plenty of leeway when it comes to choosing a circular saw for cutting metal so make sure you get the weight right. This will immediately narrow down your options and make your life easier straight off the bat.

The sweet spot is somewhere between 10 pounds and 13 pounds if you’re happy handling this weight. If you opt for one of the lighter choices, you’ll be limited to much smaller projects so think about intended usage as well as pure poundage. 

Blade

The critical factor when choosing a circular saw is the blade.

Sizing depends entirely on the scope of work you intend to carry out.

Think about the projects you’ll be working on to determine whether it makes sense to shoot for a blade only designed to slice through metal or whether you’d be happier with one offering the ability to cut wood and plastic, too.

Cold-cutting blades with carbide tips are preferable to abrasives. They’ll be more effective, cut cleaner, create almost no sparks and last longer into the bargain. CERMET tips are becoming more common and they’re also a strong choice.

Consider ease of blade changing as well as performance and durability. Get this right and you’ll be looking at a circular saw that’s devastatingly effective and a pleasure to use.

Motor Capacity

When you’re looking to confidently cut metal, you should prioritize a powerplant that’s got higher amperage and voltage but a lower no-load speed.

Cutting speed of 3500 to 3900 RPM is ideal. Go much lower and you won’t cut with enough power, shoot for a higher speed and you’d dip out on the precision front.

As with all elements of your buying decision, you need to think about the motor not in isolation but related to the type of projects you’ll be working on.

Grip

You should think about the grip in terms of both safety and ergonomics.

The more ambitious the projects you intend to take on and the longer spells you’ll be working for, the more important it becomes to have a grip that feels great and won’t be in danger of allowing the saw to slip from your grasp.

Shape and material both count here. Even if you’re planning to buy the saw online, it always pays to pop to a store so you can get the general feel of the tool before committing to purchase. We like to think of this as active window shopping!

Versatility

You should consider closely what type of metal you’ll be working with most. If you’re looking to deal with thicker material, make sure you opt for one with sufficient cutting power to handle this.

You should also think about whether you’re content to buy a dedicated metal cutting saw or you’d like one allowing you to deal with plastic and wood as well.

Variable speed on the circular saw is crucial if you want to move between various applications while optimizing cutting to suit.

Safety Features

The blade guard should come well-reviewed and with no complaints from users. This is obviously a pivotal safety feature when you’re using a circular saw.

Look for durable and appropriate materials in the saw itself so it won’t put you in any danger if you’re working in wet environments or adverse conditions.

The motor housing needs to be solid enough to bring down the chance of overheating to a minimum.

A lock-off lever to prevent the tool being accidentally fired up is a nice extra touch.

FAQ

1) Is it not possible to use a regular wood cutting circular saw with a metal cutting blade?

This is inadvisable. A standard circular saw will cut too quickly for metalwork so you really should consider a standalone saw designed expressly for working with metal to get the best results in a safe manner.

 

2) What’s the difference between carbide-tipped blades and abrasive discs?

Abrasive discs are cheaper but they’ll wear down during use and they also create a great deal of sparks. Carbide-tipped cold-cutting blades last up to 20 times longer while remaining intact for the duration of their lifespan. There’s no degradation and you can expect clean, smooth cuts with no burrs and no sparks either.

 

3) Can you make a straight cut with a circular saw?

You can if you closely follow the guide line or laser line.

 

4) Can you use metal cutting blades when you’re working with wood?

You can use your metal cutting circular saw but you’d be well advised to swap out the blade for one designed to cut through wood rather than metal.

 

5) Are these metal cutting circular saws man enough to cut through stainless steel?

No, they’re not.

 

6) What can you do to reduce the amount of sparks generated when cutting metal?

You should avoid abrasive discs and opt for carbide-tipped or CERMET-tipped cold-cutting blades.

 

7) What speed works best with metal cutting circular saws?

Anywhere from 2700 RPM to 3900 RPM works well depending on the application.

 

8) Do you need to wear safety goggles when you’re cutting metal?

Absolutely. Even if you’re not using abrasive discs, you’ll still run the risk of sparks and flying debris that could be lethal if it flies into your unprotected eyes. Don’t go without the goggles..

 

9) What’s the best size blade for metal cutting circular saws?

This depends entirely on personal preference and the scope of the projects you want to work with. The standard size is 7 ¼ inches and this is a solid, multi-purpose choice.

 

10) Are cheap metal cutting circular saws serviceable for use in a small home workshop?

Yes, they are. If you’re looking to carry out sustained work in a commercial setting, you’ll end up burning a cheap saw out and it won’t do the job you need it to. For the home hobbyist, though, there’s no need to spend a fortune to get a reasonable metal cutting circular saw.
