Best Metal Cutting Circular Saw Reviews

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.

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.

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…

Why we like it

  • 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

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.

Main Features
  • 18-volt lithium-ion battery
  • 3800 RPM
  • Four-pole ferrite motor
  • 2-inch cutting capacity

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…

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.

Why we like it

  • 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

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.

  • 3500 RPM

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…

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.

Why we like it

  • 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

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?

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

4.5/5

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.

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

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…

Why we like it

  • 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

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.

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
Rated as
4/5

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…

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…

Why we like it

  • 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

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.
