Built from high speed steel with a bright\/uncoated finish, this bit measures 0.221 inches in diameter and features a 118-degree standard point angle with web thinning for reduced thrust and easier penetration. The tapered web configuration and regular spiral flute promote efficient chip evacuation. At 2.4375 inches overall length with a 1.3125-inch flute length, it fits standard drill chucks via its straight-cylindrical shank. Licensed trades and machining professionals use this bit for production and maintenance drilling tasks.\u003c\/p\u003e\u003cp\u003eThis bit is suited for right-hand cut drilling in metalworking environments, including applications involving titanium as the primary workpiece material. The screw machine length format provides added rigidity compared to jobber-length bits, making it well-suited for use in drill presses, CNC machining centers, lathes, and hand-held drilling operations where a shorter, stiffer profile is required. It conforms to ANSI standards and falls within the R41 series. The flute-to-diameter ratio of 2.5xD supports consistent performance across the listed size range of 0.2000 to 0.2500 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.221 inch diameter with 118-degree standard point angle for general-purpose entry into metal workpieces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves point engagement\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for high-performance applications including titanium\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides increased rigidity over jobber-length bits in tight setups\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with right-hand cut for standard clockwise drilling operations\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish; no coolant-through feature — suitable for conventional cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit conforming to ANSI standards; compatible with standard straight-shank drill chucks used in drill presses, CNC equipment, lathes, and hand tools accepting straight-cylindrical shanks in the 0.2000 to 0.2500 inch size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before operation. Disconnect or de-energize the machine before changing bits.
