DEWALT DWE4120 4-1/2-Inch Paddle Switch Angle Grinder

The DEWALT DWE4120 4-1/2-inch paddle switch angle grinder brings 9 amps of overload-protected power to cutting, grinding, and surface prep work. Whether you're a professional contractor or a serious DIYer, this grinder's slim body and low-profile gear case let you work longer and get into spots bulkier tools can't reach. It's built to handle daily abuse on metal, masonry, and more.

DEWALT DWE4120 Angle Grinder: Power and Control for Tough Jobs

The 9-amp AC/DC motor spins at 12,000 RPM for fast material removal, while overload protection helps keep the tool running when you lean into heavy passes. The high-efficiency motor also runs cooler, which extends brush life and reduces downtime. With a 5/8-inch-11 spindle thread, the DWE4120 accepts almost any standard 4-1/2-inch wheel, flap disc, or wire brush.

Slim Design and One-Touch Guard for Everyday Comfort

The slim ergonomic body reduces hand fatigue during extended grinding sessions, and the 2-position removable side handle gives you control in multiple grip styles. The One-Touch guard rotates 360 degrees with a single action, so you can adjust your spark direction without wrenches. The low-profile, jam-pot gear case adds durability while letting the tool fit into tight corners.

Quick-Change Wheel Release and Tool-Free Accessory Changes

Swapping wheels shouldn't slow you down. The Quick-Change wheel release lets you remove and install discs tool-free, so you can switch from grinding to wire brushing in seconds. The paddle switch keeps the tool dead when you release your grip, adding a layer of safety on active jobsites.
