The bit measures 51\/64 inch (0.7969 inch decimal) in diameter with a 1\/2 inch Weldon shank, allowing it to seat securely in standard half-inch chucks and holders. Overall length is 6 inches with a 3 inch flute length, giving the tool a 4xD flute-to-diameter ratio. Ground to a 118-degree standard point angle with a right-hand spiral flute, the R57 series geometry suits production and maintenance drilling in a wide range of shop and field applications. The bright, uncoated finish is suitable for use without coolant.\u003c\/p\u003e\u003cp\u003eThis drill bit is used in applications where the hole diameter exceeds the available chuck capacity and a reduced shank is required to fit standard 1\/2 inch tooling. Typical settings include machine shop work, maintenance and repair operations, and fabrication environments where drilling into ferrous metal, aluminum, copper, magnesium, nickel, or synthetic materials is required. The Weldon shank with three flats resists slippage under torque, making it appropriate for use in milling machine collets and end mill holders as well as drill press chucks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e51\/64 inch drill diameter (0.7969 inch decimal) with 1\/2 inch reduced Weldon shank\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry into ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e3-flat Weldon shank provides positive drive and resists rotational slippage\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright uncoated high speed steel construction — suitable for dry cutting\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 3 inch flute length for moderate drilling depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with 1\/2 inch drill chucks, end mill holders, and Weldon-style collet systems.
