Diablo Hole Saws
Diablo Hole Saws and Kits
Diablo hole saws cover the sizes trades use most. Kits include a 17-piece plumber's bi-metal set, a 13-piece carbide plumber's set, a 16-piece electrician's set, and 9-piece and 14-piece general purpose sets. Single bi-metal hole saws are listed in sizes like 2-1/8, 3, 3-1/4, and 4-1/4 inches. Diamond grit hole saws from 3/4 inch to 2-1/2 inches cut tile and stone, and a 4-inch pilot bit is sold for replacement.
What to Look For
- Material. Bi-metal cuts wood and metal, carbide lasts longer in tough materials, and diamond grit cuts tile.
- Kit or single. Trade kits bundle the common sizes with arbors.
- Size. Match hole size to the pipe, conduit, or fixture.
- Pilot bit. Replace worn pilot bits to keep cuts centered.
