Dewalt Angle Grinder

DeWalt Angle Grinders: Power, Safety, and Cordless Freedom

DeWalt has built a formidable reputation in the angle grinder category, offering a tiered lineup of cordless and corded grinders engineered for demanding fabrication, metalworking, and construction applications. Whether you're a professional welder, a sheet metal fitter, or a serious DIYer, DeWalt's grinder portfolio — organized around the ATOMIC™, XR®, and FLEXVOLT® platforms — delivers a model matched to virtually every task and workspace.

The ATOMIC™ 20V MAX* Line: Compact Power for Tight Spaces

Designed for high performance and mobility in tight spaces, DeWalt's ATOMIC™ 20V MAX* grinders allow users executing demanding applications to transition from pneumatic to cordless. The lineup includes 4-inch and 4.5-inch angle grinder models. The ATOMIC 20V MAX 4-inch model features a brushless motor and delivers 755 maximum watts out and 12,500 no-load RPM. These cordless grinders are engineered to replace pneumatic angle grinders, delivering untethered performance and up to 44% more power than 0.7 HP rated pneumatic angle grinders. Designed to be compact and powerful for a wide range of applications, ATOMIC™ 20V MAX* tools embody the "Where Size Meets Power" philosophy.

The XR® Line: Pro-Grade Brushless Performance

Built to deliver confidence for the world's toughest pros, the DeWalt 20V MAX* XR® line represents tools that have been proven to perform at the highest level. As part of the most powerful line of 20V MAX* angle grinders, these tools are equipped with PERFORM & PROTECT™ features including the ANTI-ROTATION System, and are engineered with a brushless motor delivering up to 1,590 MWO and 9,000 RPM (no load). For users who need smart jobsite integration, the XR® grinders are TOOL CONNECT™ CHIP READY™, connecting with the TOOL CONNECT™ Site Manager app to help track and manage assets.

FLEXVOLT® 60V MAX*: Maximum Cordless Power

At the top of DeWalt's angle grinder lineup sits the FLEXVOLT® 60V MAX* family, purpose-built for the most demanding metal and concrete work. As part of the PERFORM & PROTECT™ product line, these tools feature a Kickback Brake and the Anti-Rotation E-CLUTCH® System designed to help protect the user in bind-up situations by shutting down the tool. DeWalt also offers 20V MAX* brushless tools featuring FLEXVOLT ADVANTAGE™ technology, with select grinders delivering up to 54% more power when paired with a FLEXVOLT® battery versus a standard 20V MAX* battery.

DeWalt's PERFORM & PROTECT™ Safety Architecture

What sets DeWalt angle grinders apart from many competitors is the depth of their active safety engineering. The ANTI-ROTATION System quickly stops the wheel when a pinch, stall, or bind-up event is sensed, reducing reactionary torque. The E-CLUTCH® system shuts down the motor in under a tenth of a second when a pinch or stall is detected. An electronic brake is designed to stop the wheel in less than 1 second after the trigger is released. These layered safety features make DeWalt grinders especially well-suited for professionals working in high-risk environments like structural steel, fabrication shops, and elevated job sites.

Battery Ecosystem Compatibility

Featuring patented technology that changes voltage when you change tools, FLEXVOLT® 20V/60V MAX* batteries are compatible with 60V MAX* and 300+ 20V MAX* system tools — meaning a single battery investment powers your entire DeWalt toolkit. Whether you select a compact ATOMIC™ grinder or a high-output FLEXVOLT® model, you're buying into one of the most extensive cordless ecosystems in the industry.
