Built from high speed steel with a bright, uncoated finish, this bit measures 19\/32 inch (0.5938 inches) in diameter and features a 118-degree standard point angle with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank seats securely in standard drill chucks. At 4.125 inches overall length with a 2.625-inch spiral flute, it fits compact drilling setups where a jobber-length bit would be impractical.\u003c\/p\u003e\n\u003cp\u003eThis Series R40 screw machine drill bit is rated for high-performance use and carries an ANSI specification designation. It is suited for drilling titanium as the primary workpiece material, making it appropriate for aerospace, maintenance, and precision machining environments. The regular spiral flute pattern and tapered web configuration promote chip evacuation and help maintain hole geometry. Machinists, tool and die technicians, and maintenance tradespeople working with hard metals will find this bit appropriate for production and repair drilling tasks requiring consistent accuracy in the 0.5000 to 0.6000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e19\/32 inch (0.5938 inches) diameter, screw machine length for compact clearance drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning reduces entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles titanium and other difficult workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 2.5xD flute-to-diameter ratio promotes chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — ANSI-rated, general purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit for applications requiring a 0.5938-inch diameter hole in the 0.5000 to 0.6000 inch size range, conforming to ANSI standards for screw machine length drill bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and maintenance technicians using standard drill presses, CNC machines, or hand-held power tools with a compatible chuck. Ensure the workpiece is properly secured before drilling and that drill speed and feed rate are appropriate for the workpiece material. Coolant through is not supported on this bit, so use external cutting fluid when drilling titanium or other hard metals to extend tool life and prevent work hardening. Inspect the cutting edges 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 (Inch)\u003c\/strong\u003e: 19\/32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.5938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.625 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\u003eSpiral Type\u003c\/strong\u003e: Regular\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: R40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 5998629\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702710927666,"sku":"5998629","price":54.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ef542a354898283b66fbaf0e2b5e04f.jpg?v=1788412906","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998629-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
