Hole Saw Pilots for Enlarging Holes
Easily enlarge an existing hole by giving your hole saw a stable, centered base. These pilots turn the smaller hole saw you used to make the original hole into an anchor for your larger hole saw. First, attach the larger hole saw to your arbor. Then replace your arbor’s pilot drill bit with the pilot. The smaller hole saw threads onto the pilot upside down, so the teeth face away from the material being cut. When you start to cut the larger hole, the smaller hole saw will slip into the existing hole and keep your arbor and larger hole saw aligned.
These pilots fit all brands of threaded hole saws.
Thread adapter is required for use on 1 1/8" diameter and larger hole saws to adapt 1/2"-20 threads to 5/8"-18 threads.
