Nylon Mesh Cushioned Sanding Bits
A
B
D
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.

Spiral-Wound Sanding Rolls
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.
Cone rolls are for use in holes. Unlike tapered rolls, they have a flat surface to allow for a more even finish within internal surfaces.
