Mini GrindR Quick Change Discs
Our Mini GrindR sanding discs bring a new level of performance to quick change Type R discs. Aluminum oxide abrasive grain is fused direction on a one piece polymer backing with Type R button to fit all standard holders. The one piece polymer backing is stronger than a standard button attached to a cloth or paper disc. Also the polymer backing allows for cooler grinding and much longer disc live.
These discs can be used with a holder that is one size smaller than the disc. For example you can mount a 3" disc on a 2" holder giving you added flexibility on the outer edge.
