A 1400 W, 125 mm (5") angle grinder with a 10,000 RPM motor, sealed bearings, and an adjustable guard for cutting and grinding metal.
The DEWALT DW831 is a compact, high-power grinder for metal cutting, grinding, and finishing in workshops, fabrication shops, and on site. It has a 1400 W, 12.0 Amp AC/DC motor with a no-load speed of 10,000 rpm, a 125 mm disc diameter, a trigger switch, and an M14 spindle thread. The high power-to-weight ratio gives greater efficiency and reduces fatigue, and the keyless adjustable guard can be set without tools to turn sparks away from you. Sealed ball and roller bearings help extend motor life, and external brush caps make servicing easy. The rear handle is shaped for comfort and control. It is made for welders, fabricators, mechanics, and industrial workshops.

Safety Note:
Wear safety glasses, a face shield, ear protection, gloves, and a dust mask. Always use the guard and the side handle, and hold the grinder with both hands. Use only wheels with a diameter of 125 mm and a speed rating above 10,000 RPM, and use wheels made for the job (a cutting-off wheel for cutting, a grinding wheel for grinding). Do not use damaged wheels. Let the wheel stop completely before setting the tool down, and unplug it before changing the wheel. Keep sparks away from flammable material.
