3M Unitized 38.1mm Wheel

3M unitized wheels are long-wearing with a unique spring-like action. The open-web abrasive surface resists loading, delivers consistent finishing results and creates an air cushion that minimizes undercutting and gouging. The 3M codes below indicate wheel hardness andabrasive type and cut. The abrasive grade notations describe the finish on precious and softer non-precious alloys. Use this unitized wheel on a tapered spindle.
