3M 1" Radial Bristle Discs

3M Radial Bristle Discs are long lasting and highly effective polishing and finishing tools for jewelers and metalsmiths. Stack them on mandrels and use them like natural bristle brushes — except there is no need to add polishing compound. The abrasive compound is built directly into the bristles.

Sold in packs of 12

Beware of low cost imitations-insist on genuine 3M Radial Bristle Discs

These 1" diameter bristle discs are designed for use with 1/8" diameter miniature mandrels. The 1" size is available in more aggressive grits, making them ideal for rapid scratch removal through blending applications. Simply stack individual bristle discs on a pin hole mandrel — use one disc or as many as you can fit. Four to six discs make a good brush. The result is a flexible, long-lasting polishing brush that never needs recharging.

3M Radial Bristle Disc brushes run cool to help prevent heat buildup damage and deliver an easy-to-control, uniform finish across a variety of surfaces and metals.

Note: Mandrels are not included. Discs are sold in packs of 12 per color/grit.
