25 Pack - 4-1/2" x 1/4" x 7/8" BHA Grinding Wheels for Aluminum and Soft Metals

Though light weight, versatile and strong, aluminum is soft and particularly susceptible to heat making it difficult to grind without damaging the work piece or the abrasive itself. The A/O and S/C grains can be found in high concentrations for smooth effortless use when grinding, deburring welds, or dressing.
