Tork Craft 20mm Bi-Metal Hole Saw

Cutting diameter: 20 mm – ideal for conduit entries, cable glands, and small pipe openings.

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

Bi‑metal construction:

• Electron‑beam welded HSS teeth deliver long‑lasting sharpness and heat resistance.

• Alloy‑steel cup provides flexibility and strength, resisting cracking under high torque.

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

Knock‑out slots: Allow quick and easy removal of the cut‑out core for efficiency.

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