Built from high-speed steel with a bright, uncoated finish, it features a 118-degree standard point angle and a 3\/4-inch diameter with a tight diameter tolerance of +0.0000 to -0.0012 inches. The shorter overall length of 5 inches makes it well suited for work in confined spaces or on drill press setups where rigidity matters. The web-thinned geometry reduces thrust and improves chip evacuation. Machinists, fabricators, and maintenance technicians are the primary installers of this bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for drilling alloy steel, aluminum, and similar workpiece materials in production and maintenance environments. The screw machine length format is commonly used in CNC lathes, drill presses, and turret setups where a shorter, stiffer drill profile reduces deflection and improves hole accuracy. The straight-cylindrical shank accommodates standard three-jaw drill chucks across a wide range of machines. It conforms to ASME B94.11M standards and carries the ANSI specification designation, making it a code-compliant choice for shop and field use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch diameter with a diameter tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned geometry for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003e5-inch overall length in screw machine (short) format for improved rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute spiral design for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and ANSI standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock drill bit for use in drill presses, CNC lathes, and turret machines that accept a 3\/4-inch straight-cylindrical shank.
