It measures 0.272 inches in diameter with an overall length of 2-11\/16 inches and a flute length of 1-1\/2 inches. The bit is manufactured from high speed steel (HSS) with a bright\/uncoated finish, offering a 118-degree standard point angle and a right-hand spiral flute. The straight-cylindrical shank seats securely in standard drill chucks. This is a Series R42 bit with a web-thinned, tapered web configuration for reduced thrust and cleaner entry, suited for machinists and fabricators working in production or repair environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in screw machine and general-purpose drilling operations. Its 0.272-inch diameter corresponds to Letter size I. The 2.5xD flute-to-diameter ratio and web-thinned geometry make it particularly effective when drilling titanium and other demanding workpiece materials. It is appropriate for use in drill presses, CNC machining centers, and hand-held power drills in both shop and field settings. The screw machine length provides added rigidity compared to jobber-length bits, reducing deflection in close-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.272 inch (Letter I) diameter with 118-degree standard point angle\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bright\/uncoated finish for general-purpose use\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces drilling thrust and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine length body (2-11\/16 inches overall) increases rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute for standard clockwise drilling operations\u003c\/li\u003e\n\u003cli\u003eRated for titanium as primary workpiece material per Series R42 specification\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for dimensional and performance compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for screw machine length drill bit applications requiring a 0.272 inch straight-cylindrical shank bit compatible with standard drill chucks and collet holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with drill press and rotary tool operation. Ensure the machine spindle is fully stopped and the chuck is secured before inserting or removing the bit. Use appropriate cutting fluid or coolant when drilling titanium or hard alloys to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear or chipping before each use and replace if the point is damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.272 inches (Letter I)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5998927\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51711271338290,"sku":"5998927","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e90f964911bee998bfbd70aff9a08a7b.jpg?v=1788475191","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998927-0-272-in-hss-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
