This 12-pack of 5/16″ HSS Black & Gold Split Point Stub Drill Bits from the Contractor Series is designed for metal drilling in tight spaces. Short, stub-length bits minimize deflection; split-point geometry helps starting holes accurately without a center punch; and the HSS construction provides wear resistance for drilling through steel and other metals.
