Built from high speed steel (HSS) with a bright, uncoated finish, it measures 11\/64 inch (0.1719 inches) in diameter and carries a 118-degree standard point angle. The shorter screw machine length body — 2.125 inches overall — gives machinists and toolroom technicians better rigidity in drill press, turret lathe, and CNC applications where stub-length tooling is preferred. Web thinning reduces thrust force at the point and improves chip clearance on entry.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling in ferrous and non-ferrous metals, including titanium as noted by the manufacturer. The Series R40 designation identifies it as a general-purpose HSS line built to ANSI standards. It is commonly used in machine shop environments, maintenance and repair operations, and trade applications where a compact drill profile reduces deflection and improves hole accuracy in short-depth bores. The straight-cylindrical shank accepts standard drill chucks without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/64 inch (0.1719 inches) 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\u003eScrew machine (stub) length — 2.125 inches overall — for added rigidity\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute and 1.0625-inch flute length\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces entry thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit for standard drill chucks accepting straight-cylindrical shanks in the 11\/64 inch diameter range, conforming to ANSI standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and toolroom technicians using standard drill press, lathe, or CNC equipment. Secure the shank fully in the chuck and verify runout before drilling. Ensure the workpiece is clamped securely and appropriate cutting fluid is applied when drilling titanium or hardened metals to extend tool life. Inspect the cutting edges for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 11\/64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1719 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0625 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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: R40\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: 5998587\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51716020633906,"sku":"5998587","price":46.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ec91b8d58e04c919260a9d1a8fa82c.jpg?v=1788521122","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998587-11-64-in-hss-screw-machine-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
