Hole Saw Arbors with Pilot Drill Bit
Pilot
Drill Bit
Secure your hole saw to a drill or drill press with these arbors. An included pilot drill bit centers your cut and guides the saw. These arbors fit all brands of threaded hole saws.
Arbors with retractable locking pins detach quickly—just pull back the collar and unthread your hole saw.
Long-life pilot drill bits are carbide tipped, so they last up to twice as long as high-speed steel.
Arbor thread adapters let you use arbors with 1/2"-20 threads with hole saws that have 5/8"-18 threads.

Hole Saw Arbor Extensions
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.
