Measuring 0.12 inches in diameter with an overall length of 1-7\/8 inches and a flute length of 7\/8 inch, this Series R41 bit delivers a compact stub-length profile that reduces deflection and improves hole accuracy in short-reach setups. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. Licensed machinists, maintenance mechanics, and industrial tradespeople install and use this bit in drill press, CNC, and hand-drill operations.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling titanium and general-purpose metals where a short, rigid drill geometry is required. The 2.5xD flute-to-diameter ratio provides adequate chip clearance without sacrificing rigidity. The straight-cylindrical shank fits standard drill chucks. Right-hand spiral flutes pull chips out of the hole during operation, keeping the cutting edge clear. The bright, uncoated finish is appropriate for dry cutting or cutting with standard coolant fluids where a coated surface is not required. No coolant-through capability is built into this bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.12 inch diameter, wire size 31, screw machine (stub) length for reduced deflection\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for lower entry force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for general-purpose and titanium workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish, ANSI specification compliant, Series R41\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw machine length replacement or production drill bit for applications requiring a 0.12 inch diameter hole in general-purpose and titanium workpieces, conforming to ANSI standards for straight-shank stub-length drill bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and maintenance mechanics in standard drill chucks accepting straight-cylindrical shanks. Ensure the drill press, CNC spindle, or hand drill is fully powered down and secured before changing bits. Verify chuck jaw condition and tighten securely to prevent bit slippage during operation. Follow shop safety protocols and applicable ANSI machining guidelines when drilling titanium or hard alloys, including appropriate eye protection and chip management.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inch\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\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R41\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: 0.04167 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 5998865\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51689419964722,"sku":"5998865","price":38.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93e27598d2b5d8d54a9c014c74974fca.jpg?v=1788259202","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998865-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
