Value Collection 01340579 Reduced Shank Drill Bit Hss

Product Description

The VALUE COLLECTION 01340579 is a reduced shank twist drill bit designed for general-purpose drilling in metal, wood, and plastics. The bit features a 57/64 inch (0.8906 inch decimal) cutting diameter paired with a 1/2 inch straight-cylindrical shank, allowing it to be chucked in standard 1/2 inch drill chucks even though the cutting diameter is larger. Constructed from high-speed steel with an oxide finish, it delivers adequate hardness and corrosion resistance for everyday shop and field use. The 118-degree standard point angle suits a wide range of common materials. Right-hand cutting spiral flutes run 3 inches in length for efficient chip evacuation during drilling operations.

This drill bit is suited for machinists, maintenance technicians, fabricators, and trade professionals who need to produce 57/64 inch holes without requiring a larger chuck capacity. The reduced shank design makes it practical for use in drill presses, hand drills, and benchtop machines equipped with 1/2 inch chucks. With a 6 inch overall length and a maximum drilling depth of 3 inches, it handles standard through-hole and moderate depth drilling tasks in production and repair environments.
