Longer lasting than grinding bits, these abrasive cones remove heavy amounts of material and leave a rough surface texture. They have a threaded insert that attaches to the spindle on a straight grinder. Use in corners and inside castings.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

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. Also known as cartridge rolls. A shank adapter is required (sold separately).
