Sized at 0.266 inches (17\/64 inch, Letter H), it features a 118-degree standard point angle and a bright\/uncoated finish. The right-hand spiral flute geometry and web-thinned, tapered web construction reduce thrust and improve chip evacuation. At 2-11\/16 inches overall length with a 1-1\/2 inch flute length, this bit fits standard drill chucks via its straight-cylindrical shank. It is built to ANSI standards and suited for high-performance general-purpose drilling.\u003c\/p\u003e\n\u003cp\u003eThis screw machine length drill bit is intended for use in drill presses, CNC machining centers, and hand-held power drills where a shorter, more rigid bit is preferred over jobber length. The primary listed workpiece material is titanium, though the Series R42 HSS construction also handles steel, aluminum, and other common shop materials. The 2.5xD flute-to-diameter ratio supports stable chip clearance in shallow to moderate-depth holes. Typical users include machinists, tool and die makers, and maintenance technicians working in production or job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.266 inch (17\/64 inch, Letter H) diameter in screw machine length for added rigidity\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for high-performance general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with cutting fluids and coolants\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit conforming to ANSI standards, suitable for use in drill presses, lathes, and CNC equipment accepting straight-cylindrical shank bits in the 0.2500 to 0.3000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians. Secure the straight-cylindrical shank firmly in the drill chuck before operation and verify chuck key is removed before powering the machine. Apply appropriate cutting fluid when drilling titanium or hardened steel to extend bit life and maintain dimensional accuracy. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.\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: 0.266 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 17\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: H\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\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R42\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\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: 5998923\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709913825586,"sku":"5998923","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a62684a7dfe450de02e6a7a0905b4dd1.jpg?v=1788462207","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998923-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
