Built from cobalt steel with a TiAlN coating, it delivers extended tool life and heat resistance in demanding production environments. The bit measures 1.75 inches overall length with a 0.75-inch flute length and cuts a 0.0820-inch diameter hole corresponding to wire gauge size 45. A 135-degree split point reduces walking and lowers thrust requirements at the start of the cut. This bit is sold individually and is used by machinists, tool-and-die workers, and precision metalworking shops.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are shorter than jobber-length bits, which increases rigidity and reduces deflection when drilling in confined spaces or on CNC machining centers, drill presses, and screw machines. The size 45 wire gauge designation makes this bit suited for small-diameter precision work including pilot holes, tap drilling, and close-tolerance production runs in steel, stainless, cast iron, and other hard alloys. The straight-cylindrical shank fits standard drill chucks without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction resists heat buildup during high-speed cutting in hard metals\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends cutting edge life and reduces friction\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and prevents bit walk\u003c\/li\u003e\n\u003cli\u003eScrew machine length body increases rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with parallel web configuration for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for size 45 wire gauge screw machine length drill bits used in standard drill chucks accepting straight-cylindrical shanks on CNC machining centers, drill presses, and screw machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and replaced by machinists and tool-and-die professionals.
