Powercraft Reduced Shank Drill Bits are heavy-duty twist drill bits designed for drilling large-diameter holes using standard 1/2-inch drill chucks. Featuring a reduced 1/2-inch shank, these drill bits allow larger cutting diameters to be used with portable drills and drill presses without requiring a larger chuck. Manufactured for strength, precision, and durability, they are ideal for drilling through steel, cast iron, aluminum, brass, and other ferrous and non-ferrous metals in industrial, fabrication, maintenance, and construction applications. Powercraft offers sizes from 9/16" to 1", all with a 1/2" reduced shank for compatibility with common drilling equipment.
