Grinding in tight places around irregular surfaces is the specialty of this Milwaukee Die Grinder. The 5192 comes with 1/4 inch collet but will accept 1/8 inch collet as well. A full array of mounted points allows you to grind many shapes and diameters. At 21,000 RPM with a 4.5 amp motor, this tool means business. A maximum 2 inch reinforced wheel or 1-5/8 inch non-reinforced wheel can be attached to this versatile grinder for deburring and shaping. On-off toggle switch, flip on and go to work.
