Grinding Cones for Straight Grinders
2
3
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 are aluminum oxide, which is the most common abrasive used in grinding metals.
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.
