Milwaukee 3674-20 Variable Speed Angle Grinder Paddle

Product Description

The MILWAUKEE 3674-20 is an M18 FUEL cordless variable speed braking angle grinder with a paddle switch, designed for professional grinding and cutting applications in the trades. Powered by a POWERSTATE brushless motor, it delivers between 5,000 and 8,400 RPM across four selectable speed settings, giving technicians and fabricators precise control over material removal. The RAPIDSTOP brake brings the wheel to a halt quickly after trigger release, reducing exposure risk on the job. REDLINK PLUS electronics manage performance and protection between tool and battery. This grinder handles disc sizes from 4.5 inches up to 7 inches and uses a 5/8-inch-11 spindle compatible with standard grinding and cutting accessories.

The 3674-20 is built for demanding trade applications including metal fabrication, weld grinding, masonry cutting, and surface prep in both residential and commercial environments. The compact body profile allows the tool to reach into confined spaces while still handling large-diameter discs. The variable speed dial lets the operator match wheel speed to the material and application, reducing the risk of workpiece damage. It is compatible with all M18 batteries and supports ONE-KEY asset tracking and tool customization for fleets managed by contractors and service companies.
