3M 3/4" Radial Bristle Discs Various Grits-Packs of 12

These are the discs a bench reaches for when a polishing progression has to follow a curve or a setting without loading up compound: the abrasive is built into the bristles, so nothing needs recharging. The 3M 3/4" Radial Bristle Discs are professional-grade polishing and finishing discs for flex shaft use, sold in packs of 12 individual discs. They stack onto a pin-hole mandrel, and you can run one disc or stack four to six together to build a flexible brush suited to the job.

The discs are long-lasting and cool-running, giving a uniform, easy-to-control finish without the heat buildup that damages delicate work. Seven grits cover the full spectrum from rapid scratch removal to final high-polish finishing, so a complete progression can be built for metal, stone settings and other jewelry surfaces.
