Aluminum oxide A with cooling topsizing (COOL) for grinding on materials with poor thermal conduction such as stainless steel (INOX) and aluminum.  Specially formulated for non-loading grinding performance on aluminum and soft non-ferrous metals.  For surface grinding, weld dressing, blending, chamfering and deburring.

Use only grit sizes 40 and 60 for aluminum.

• Less heat generation compared to conventional flap discs
• Special top-sized abrasive material prevents loading on soft metals such as aluminum.
• 7/8" Arbor Bore
