3M 3" Radial Bristle Disc 6 Ply Brush - 120 Grit White

A pre-assembled 3" 3M Radial Bristle Disc brush ready to mount directly on a jeweler's polishing lathe. This unit combines 6 individual 3M Radial Bristle Discs stacked together and mounted on a 2-piece plastic tapered spindle mount configured for right-hand side use. The tapered spindle mount is designed to fit the tapered spindles traditionally found on jeweler's polishing lathes, including the 116.549 model.

At 120 grit, this white disc brush delivers consistent, controlled finishing action suitable for polishing and surface refinement on metal jewelry and components. Purchasing this assembled unit eliminates the need to stack and mount individual discs—it arrives ready to install and use immediately.

For left-hand side lathe use, a separately available tapered spindle mount version is offered (116.549L).
