Starrett SM85 TCT Sheet Metal Holesaw 85mm

The Tungsten Carbide Tipped (TCT) Stainless Steel hole saws are ideal for cutting high alloy and stainless steels, non-ferrous light metals and reinforced fabrics. The tough tungsten carbide tipped teeth have a positive cutting angle which provides fast and efficient removal of chips and swarf. It is recommended for use on sheet metal up to 1/8" (3mm) thick.

Important Safety Recommendations:

• Should only be used to cut flat surfaces
• Maximum material thickness of 2mm for stainless steel, mild steel and non-ferrous metals
• Recommended operating speed, 850 to 1200 rpm
• We recommended saws above 50mm diameter should only be used on pillar drills. Smaller diameters can be used with both handheld drills and pillar drills
• Safety glasses and gloves are recommended
• Do not push too hard, to avoid an impact of the TCT teeth. Once the teeth touch the material, drill with slight steady pressure
