Starrett SM21 Metal Hole saw, Stainless Steel Sheet, 21 mm

Ideal for production cutting of high alloy and stainless steels, non ferrous light metals and reinforced fabrics. Tungsten carbide tipped teeth provide superb product life and cutting performance. The teeth have a positive cutting angle which provides fast and efficient removal of chips and swarf plus a high cutting accuracy. Safety stop at the base of the holesaw prevents drilling beyond maximum cutting depth of 13mm (1/2). Complete assembly - no need to purchase a separate arbor and pilot drill. Replacement pilot drills available.)
