Starrett SM70 70mm TCT Sheet Metal Holesaw

Product Overview:

Tungsten Carbide Tipped Stainless Steel (Sheet Metal – SM) Hole Saws are ideal for cutting high alloy and stainless steels, non-ferrous light metals and reinforced fabrics at much faster speeds than is possible with a bi-metal hole saw. Its tough tungsten carbide tipped teeth have a positive cutting angle which provides fast and efficient removal of chips and swarf. It is recommended for cutting sheet metal up to 3mm (1/8”) thick.

Product Features:

• Split-point drill for faster penetration and self-centring helping keep the drill on target and prevent wandering
• Ideal for production cutting, and particularly suitable for use in drills with limited speed control
• Tungsten carbide tipped teeth provide superb product life and cutting performance
• Replacement pilot drills are available
• Solid one-piece construction, with complete assembly including arbor and pilot drill
• Fitted with ejector spring for easy core removal
• Step drill for faster cuts in thinner materials
• Progressive carbide tooth grind offers faster cuts with minimal snagging, better swarf removal, minimising heat build up and prolonging the saw’s life.
• New shallow gullet design increases tooth strength
• Safety stop at the base of the hole saw prevents drilling beyond the maximum cutting depth of 13mm (1/2″)
