The 3M Mini Mandrel is an accessory that attaches to your die grinder or drill. It holds a 1-inch wide strip of Scotch-Brite non-woven material. Secure its shaft into the collet assembly of your drill chuck or rotary power tool to clean, polish or deburr the inside diameter of the workpiece.
The 2-7/8-inch long mini mandrel is useful in metal fabrication, woodworking and millwork, in the manufacture of medical instruments, turbine engine manufacture, plumbing, and other industries where finishing internal diameters is necessary.
