The default hole saw kit for pros and serious DIYers: one bi-metal set that drills clean holes in wood, drywall, plastic and thin metal, backed by a lifetime tooth warranty.
Pros
- Bi-metal teeth cut wood, drywall, sheet metal and plastic with one saw set - true all-purpose
- Wide 3/4 in to 4-3/4 in range covers everything from 1/2 in conduit to 4 in vent holes
- Carries a lifetime tooth-break warranty, which is rare for a consumable
Cons
- Big investment for occasional use - most DIYers only need two or three of the 22 sizes
- Slow and prone to overheating in thick hardwood or stacked material without pilot backouts
- HSS teeth dull quickly if pushed through cement board, tile or nail-embedded wood
