As we hit the mid-point of our best angle grinder reviews, something you might not be expecting…
A cordless disc grinder from Ryobi, pioneers of cord-free tools with a stellar reputation for providing woodworkers and craftsmen the world over with the total versatility of cordless tools without any noticeable reduction in quality.
Glance first at the main features then we’ll run down why the Ryobi P421 makes sense for anyone seeking out a capable and total flexible angle grinder at a very keen price…
It’s common knowledge that corded power tools deliver generally superior performance. This is no surprise. What might come as a surprise, though, is just how effective this neat little cordless grinder from Ryobi is when set against comparable corded models.
First thing’s first, this disc grinder is part of Ryobi’s ever-growing ONE+ range and is sold as a bare tool. When you’re budgeting, factor the battery and charger into the equation if you don’t already have them in your collection. Bottom line, this makes the grinder a reasonably expensive proposition. On the flip side, if like many woodworkers you are already invested in this neat system, you’ll be able to make considerable savings buying the tools and using your battery between them.
As well as the standard 18-volt lithium-ion batteries, you’ll also be able to accommodate the older nickel-cadmium batteries if you have any you need to find a home for so the Ryobi is a very forgiving beast in terms of compatibility.
While the 18-volt lithium ion battery only rotates the wheel at 6500 RPM, the power you’ll get from the Ryobi is more than fit for purpose. As with the Makita, it’s a sound example of why you should examine the overall package rather than focusing narrowly on a single number.
Comfort is everything with tools. The grip is notched and rubberized meaning you won’t find your grinder slip from your grasp even if you have oily or greasy hands. With the grip turning through 90 degrees and the side handle itself packing three position settings, you’ll be able to work in comfort while also positioning your tool wherever you need it to go.
This angle grinder tips the scales at just over 5 pounds so, while it’s not as lightweight as some of its competitors, it’s certainly not unwieldy enough to feel uncomfy. It has an attractively small footprint measuring in at 8 x 12 x 8 inches so storage won’t be an issue.
The tool-free guard makes sure that safety is front and center and this is super-simple to position as you see fit.
The disc changing is not tool-free but all you’ll need is a pin wrench which Ryobi throw in. This is stored onboard so you won’t need to worry about misplacing it or breaking your workflow to find it when you want to switch applications.
A regulation 4 ½-inch grinding disc comes included so, as long as you have the battery issue in hand, you’ll be up and running as soon as your package lands.
Whether you want to cut tile or clean rust, grind back surplus metal or fix some grout, the Ryobi P421 will make a fine and free-ranging addition to your toolkit.
