Grinding Bits for Stainless Steel
Bits stay cool during grinding so they won’t mar or discolor stainless steel.
Bits are zirconia alumina, which grinds faster and lasts longer than aluminum oxide. They are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.
Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Grinding Cones for Straight Grinders
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.
Head diameter is measured at the widest point.
Cones for steel and stainless steel are zirconia alumina, which grinds faster and lasts longer than aluminum oxide.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
