A 28-piece bi-metal hole saw kit (22 saws, 3/4-4-3/4 in.) that cuts wood, drywall, sheet metal, and PVC from one set, from 1/2 in. conduit to 4 in. vent holes, backed by a lifetime tooth-break warranty. It's a big buy when most DIYers use a few sizes, runs slow in thick stock, and the HSS teeth dull fast in cement board or tile.
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
