- Grinding welds
- Metal removal
A 4-1/2 in. Type 27 depressed-center grinding wheel (1/4 in. thick, A24R aluminum oxide, 3-ply fiberglass) for knocking down welds, beveling edges, and removing metal fast. The thick body removes material aggressively, and three fiberglass sheets take the side pressure of grinding. It's far too thick to cut stock and can gouge thin sheet.
Pros
- Thick 1/4 in body with high grain concentration removes weld beads and metal aggressively
- Three full sheets of fiberglass make it tough enough for the side pressure grinding demands
- Depressed center lets you grind at a 20 to 30 degree angle with good clearance from the guard
Cons
- Far too thick to cut through stock, so you still need a separate cut-off wheel
- Removes material fast, which makes it easy to gouge or over-grind thin sheet
- Wears to an unusable stub and generates heavy sparks and dust; eye and face protection are mandatory
