Starrett FCH2532 Constant-Pitch Fast Cut Bi-Metal Hole Saw 20mm / 25/32 Inch

20mm (¾") Bi-Metal Constant-Pitch Fast Cut Hole Saw – Precision Cutting for Thin Gauge Steel & Tubing

This 20mm (¾") bi-metal hole saw is ideal for clean, controlled cutting through stainless steel, mild steel, and other thin-walled metals up to 3mm thick. Designed with a constant-pitch tooth profile, it minimises snagging and delivers smooth, fast cuts—perfect for use in electrical, mechanical, and industrial applications requiring smaller diameter holes.

• Constant-Pitch Tooth Design: Provides a smooth, vibration-free cut and reduces grabbing on irregular or curved surfaces.
• Bi-Metal Durability: Features high-speed steel cutting teeth and a tough alloy body, offering excellent wear resistance and long service life.
• Optimised for Thin Gauge Material: Ideal for mild and stainless steel sheet and tube with a wall thickness of up to 3mm (1/8").
• 5½ TPI Tooth Pitch: Delivers precise, clean cuts in thinner materials—minimising burr and deformation.
• Cutting Depth: 41mm (1 5/8") makes it suitable for a wide range of installation and fabrication tasks.
