The secure bond of the roll to the integrated shank prevents loosening from vibration while sanding, resulting in a smooth finish. Great for precision grinding applications when you need to sand your surface to a specific tolerance. Use these rolls in channels, fillets, recesses, contours, sidewalls, and other hard-to-reach spots. As the outer layer wears away, new abrasive is exposed.

The most common abrasive material, aluminum oxide is hard enough to sand steel and wood. It costs less than zirconium oxide ceramic but wears down faster.

Coated with aluminum oxide ceramic, these rolls are sharp and dense enough to shape hard metals such as stainless steel, nickel, and cast iron without dulling quickly. The abrasive grit continually fractures to produce new, sharp cutting edges. It sands faster and lasts longer than aluminum oxide but requires more force to abrade properly. As the outer layer wears away, new abrasive is exposed. A shank adapter is required (sold separately).
