Please confirm the size and contents upon arrival. Features a durable bi-metal design: a high-speed steel (HSS) cutting edge welded to a flexible alloy steel body.

Perfect for electricians and DIY projects like installing lights, vents, fans, and cables. Features a quick-connect arbor for simple setup. Just insert the pilot bit, align the hole saw with the locking pins, and hand-tighten the screw using the included hex key. Ensures a secure fit without over-tightening. The arbor fits most standard 3/8" and 1/2" chuck drills. This product is backed by our 12-month warranty.
