The ceramic alumina grit in these bits is sharp and dense enough to shape hard metals such as stainless steel, nickel, and cast iron without dulling quickly. It continually fractures to produce new, sharp cutting edges. Ceramic alumina sands faster and lasts longer than aluminum oxide but requires more force to abrade properly. Slip a cap onto the head of a shank (sold separately) and sand small, recessed, and hard-to-reach areas.

The abrasive-embedded mesh construction gives you more control over sanding pressure, creating finer and more consistent finishes in small, recessed, and hard-to-reach areas.

Coarse grade is for aggressive deburring and cleaning.

Medium grade is for deburring and polishing.

Fine grade is for light blending and finishing.

As the outer layer wears away, new abrasive is exposed. Also known as cartridge rolls. A shank adapter or tapered spindle with a shank is required (both sold separately). The most common abrasive material, aluminum oxide is hard enough to sand steel and wood. The diameter listed is for the large end of the roll.

Straight rolls are for use in channels, fillets, recesses, contours, sidewalls, and other hard-to-reach spots.

Tapered rolls are for use on angles, corners, concave contours, funnel-shaped recesses, and other intricate shapes.

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. Also known as cartridge rolls.

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