Pilot Drill Bits for Hole Saw Arbors
As you use your hole saw blades, the pilot bit in the arbor will eventually wear out. Rather than buying a full replacement arbor, you can just buy a new pilot bit and replace the old bit.
These pilot bits are made from High Speed Steel (HSS), and fit all hole saw arbors. They are available in lengths of 3″ and 4″. There is even a carbide tipped 4″ bit available if you need extra cutting power.
