Tork Craft 21mm Bi-Metal Hole Saw

Cutting diameter: 21 mm – perfect for conduit entries, cable glands, pilot holes, and small pipe penetrations.

Cutting depth: ±38 mm – suitable for sheet metals, timber, plastics, and drywall.

Bi‑metal construction:

• HSS cutting teeth are electron‑beam welded to a tough alloy‑steel cup for long life and flexibility.

• Robust body absorbs torque and resists cracking under heavy use.

Variable‑pitch teeth: Reduce vibration and noise, improve chip clearance, and deliver smoother cuts.

Knock‑out slots: Allow quick and easy removal of the core plug after drilling.

Mandrel compatibility: Fits standard ½″‑20 UNF pin‑type arbors such as Tork Craft TC17002 (not included).
