Starrett holesaw, 21 mm (13/16”), carbide grit

Description

Constructed of hardened, heat and abrasion resisting high speed steel teeth with a tough alloy body and cap. This gives them exceptional strength, durability and shatter resistance for user safety. They will cut any wood, metal or plastic in either a hand-held drill or drill press. Cut ceramics, glass resins, asbestos and other abrasive materials that would wear out conventional saws. They have high tough steel body with multiple carbide grits permanently bonded to the teeth. Very efficient at high speeds, they prevent binding action and cut smooth holes. Cutting depth is 1.5/8″.
