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.
