Milwaukee Tool 6143-31 Corded Angle Grinder 5 in 12000 Rpm

Product Description

The MILWAUKEE TOOL 6143-31 is a corded small angle grinder designed for heavy-duty cutting, grinding, and surface preparation on metal and masonry. It runs on 120 volts and draws 11 amps, driving a 5/8-11 spindle to a no-load speed of 12,000 RPM. The tool ships with Electronic Overload Protection to guard the motor against damage under load, and a Rapid Stop Brake that brings the wheel to a halt quickly after the paddle switch is released. A 100% tool-free design allows wheel changes and guard adjustments without a separate wrench for most operations. Licensed tradespeople and experienced fabricators working in mechanical, industrial, and construction trades rely on this grinder for consistent runtime and motor longevity.

The 6143-31 accepts 4-1/2 inch and 5 inch Type 27 and compatible grinding, cutting, and flap-disc wheels via the 5/8-11 spindle. The paddle no-lock switch style prevents accidental restart, which is a common jobsite requirement in commercial construction and industrial maintenance environments. A lanyard-ready design supports work-at-height safety protocols. The included side handle and T27 guard configure the tool for standard grinder use out of the box. This grinder fits residential, commercial, and light industrial applications wherever corded power is available.

Installation Notes

Angle grinder service and wheel changes should be performed with the tool unplugged from the power source. Always inspect the wheel for cracks or damage before mounting and confirm the wheel speed rating meets or exceeds the tool RPM. Ensure the wheel guard is properly positioned before operation. Follow ANSI B7.1 and applicable jobsite safety standards when operating abrasive wheels.
