Starrett Stainless Steel 21mm Arbor

The Starrett Tungsten Carbide tipped stainless steel sheet metal 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. It’s tough tungsten carbide tipped teeth have a positive cutting angle which provides fast and efficient removal of chips and swarf. Recommended for use on a bench drill for greater cutting stability. 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.
