What the AI looks for in Hole Saws
- Exact diameter
- Match the diameter to the fitting spec (lockset, pipe or box), not to the nominal pipe size Pipe and conduit nominal sizes differ from their actual outside diameters.
- Tooth pitch
- Variable-pitch bi-metal teeth suit mixed materials; carbide suits hard or abrasive ones Variable pitch reduces chatter and clogging.
- Thread fit
- Confirm the saw uses a 1/2-20 or 5/8-18 thread that matches your arbor Single saws usually ship without an arbor.
- Depth
- Check cutting depth against the material thickness Shallow saws need two-sided cuts on thick stock.
Brands that matter
- Lenox: Speed Slot bi-metal saws.
- Milwaukee: Hole Dozer and Big Hawg.
- Starrett: Deep Cut saws.
- Diablo: Carbide options for tough materials.
