Overview

The Milwaukee 2680-20 M18 cordless grinder delivers robust metal cutting and grinding performance in a compact, job-site ready package. With a 4-1/2 inch wheel, it can tackle metalwork, PVC pipe, and edge refinishing, all while staying maneuverable in tight spaces. A powerful 4-pole motor drives the wheel up to 10,000 RPM, giving you material removal speed when you need it most. The rubber-textured handle and a 3-position side handle provide ergonomic control, helping you maintain steady cuts and precise grinds across a range of angles.
