It features a 1-7\/64 inch (1.1094 inch) cutting diameter with a 1\/2 inch Weldon flat shank, allowing secure tool engagement in compatible chucks and holders. The 118-degree standard point angle suits a wide range of ferrous and non-ferrous materials. Constructed from high-speed steel with a bright uncoated finish, this bit delivers reliable performance on drilling operations where coatings are not required. Licensed machinists, maintenance techs, and fabrication professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for general-purpose drilling into ferrous metals as a primary workpiece material, with secondary suitability for aluminum, copper, magnesium, nickel, titanium, synthetic materials, and cermet. It fits applications where a reduced shank is needed to use a larger-diameter bit in a standard 1\/2 inch chuck. The 3-inch flute length and 6-inch overall length provide sufficient reach for most bench drilling, drill press, and milling machine setups. The Series R57 designation places it within PRECISION TWIST DRILL's standard reduced shank line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-7\/64 inch cutting diameter with 1\/2 inch reduced Weldon flat shank for use in standard 1\/2 inch chucks\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\u003eHigh-speed steel construction with bright uncoated finish\u003c\/li\u003e\n  \u003cli\u003e3-inch flute length with regular spiral flute type for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with a maximum drilling depth of 3 inches\u003c\/li\u003e\n  \u003cli\u003eThree flats on Weldon shank prevent bit slippage under load\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut; meets ANSI standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit for use in drill presses, milling machines, and power drills equipped with a 1\/2 inch chuck or Weldon-style tool holder.
