3M Radial Bristle Discs deliver long-lasting, effective polishing and finishing without the need for separate polishing compound — it's built right into the bristles. Simply stack the individual discs onto the included pin hole mandrel and use them like a natural bristle brush. Four to six discs stacked together make an excellent brush, giving you a flexible, rechargeable-free polishing tool that runs cool to help prevent heat damage and delivers a uniform, easy-to-control finish.
This convenient kit includes 12 discs each of six grits — from aggressive cutting to ultra-fine finishing — plus one mandrel, so you have everything needed to take a piece through a complete polishing progression.
