DeWalt Grinder

Dewalt offers an array of angle grinders for every application. You can find tool-only options, angle grinder kits, and a range of sizes to suit every purpose. Choose from corded or cordless options and varying power levels, plus concrete grinder units for heavy-duty jobs.

Types of Angle Grinders from Dewalt

Dewalt’s angle grinders span smaller models with lower amp output to larger grinders that can tackle your toughest jobs. Integrated safety features and high-performance accessories make every grinding task a snap.

A cordless angle grinder, such as the 4.5-inch Small Angle Paddle Switch Grinder with Brake and No Lock-On, offers an 11-Amp motor that delivers high speeds in demanding scenarios. The brake wheel slows quickly, and a one-touch guard lets you adjust the guards quickly. A comprehensive dust ejection system also aids in expanding motor life.

While cordless tools have their place and function, Dewalt’s best-selling angle grinders are corded models like the 5-inch Brushless Paddle Switch Small Angle Grinder with Kickback Brake, No Lock. With a long-lasting brushless motor and a quick-stop, automatic brake, the paddle switch grinder also incorporates a two-stage trigger for safety.

Is DeWalt the Right Brand of Angle Grinder for You?

DeWalt has been a staple in many garages, shops, and industrial setups, so it’s no surprise that many of their tools are super accommodating to the user. Their main focus is ergonomic designs and user-friendly features. Nonetheless, here are the basics of what to expect with DeWalt’s angle grinders:

Tool-less Adjustments

What makes DeWalt’s angle grinders so user-friendly is their system of tool-less adjustments and changes. You don’t need special tools for adjusting the guard and/or changing the disc so this can save a generous amount of time. You will benefit from this if you’re often in a hurry trying to finish a project or meet a deadline.

Tool Weight

Many of DeWalt’s angle grinders are lightweight (around three to four pounds) that all users can power through projects without feeling fatigued. You will also find their light weight useful when working with overhead projects or awkward positions for hours.

Switch Types

DeWalt’s angle grinders are mostly made with slide switches but others have a paddle switch as well. Both of them are good at preventing accidental triggers, although a paddle switch style is more useful for those who wear gloves and want a better grip on the tool.

Wheel Size

As DeWalt accommodates mostly 4-1/2-inch wheel sizes, it can be implied that their angle grinders are for light to medium-duty work. However, I mentioned a different model above, in which you can use a larger wheel, so there are exceptions to their lineup.


The majority of angle grinders from DeWalt are backed by a 3-year limited warranty, as well as a 1-year free service and 90-day customer satisfaction (money-back guarantee). Having a long warranty period is a plus point if you want to get the most out of your power tool and use it extensively for projects while reducing maintenance costs and hassle.
