The bit features a 118-degree standard point angle with web thinning and a tapered web configuration, which reduces thrust and improves chip clearance at the start of a cut. A fast spiral flute pattern promotes efficient chip evacuation during drilling operations. With an overall length of 4 inches and a 2-3\/4-inch flute length, this bit suits general-purpose drilling in a wide range of production and maintenance applications. It meets ASME B94.11M standards and carries an ANSI specification designation.\u003c\/p\u003e\u003cp\u003eThe C03070 is rated for general-purpose drilling with aluminum listed as the primary workpiece material, though its HSS construction and standard geometry also support use in wood, plastics, and softer ferrous metals in light-duty scenarios. The straight-cylindrical shank (0.2460 inches in diameter) accepts standard 3-jaw drill chucks used on hand drills, drill presses, and CNC drilling equipment. This bit is well suited to HVAC, plumbing, and electrical tradespeople who need reliable, repeatable hole sizing for conduit, sheet metal, and structural framing work on the job site.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter D size — 0.2460 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eFast spiral flute design promotes rapid chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bright uncoated finish\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 3-jaw chucks\u003c\/li\u003e\n\u003cli\u003eCompliant with ASME B94.11M and ANSI specification requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard 3-jaw drill chuck that accepts a 0.2460-inch straight-cylindrical shank, including hand drills, drill presses, and CNC drilling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall the bit fully into the chuck jaws and tighten securely with a chuck key before drilling.
