Reducing setup time by allowing large-diameter drilling in standard 1/2" (12.7 mm) chucks, this 5-pack drill bit set includes 9/16" (14.3 mm), 5/8" (15.9 mm), 3/4" (19 mm), 7/8" (22.2 mm), and 1" (2.5 cm) sizes. Each high-speed steel bit utilizes a 135° split point for immediate penetration in wood, iron, and steel. These black oxide-finished bits are built for production, maintenance, and portable drilling tasks where a 1/2" (12.7 mm) reduced shank is required.
