With a 0.157 inch (number 22 wire gauge) diameter and a 118-degree standard point angle, this bit delivers clean entry and consistent performance in production and maintenance environments. The web-thinned, tapered web construction reduces thrust and improves chip evacuation. At 2.125 inches overall length with a 1.0625 inch flute length, the shortened body gives rigid support in close-quarters drilling. Licensed HVAC technicians, machinists, plumbers, and electricians working with sheet metal or structural components will find this bit well suited to repetitive-cycle work.\u003c\/p\u003e\n\u003cp\u003eThis bit fits screw machine and drill press applications where stub-length rigidity is preferred over jobber-length reach. The straight cylindrical shank seats securely in standard three-jaw chucks and quick-change holders. The regular spiral flute and 2.5xD flute-to-diameter ratio handle chip clearance efficiently in the 0.15 to 0.20 inch diameter range. The bright uncoated finish is appropriate for general-purpose use across a wide range of workpiece materials, with a listed primary suitability for titanium per the manufacturer specification. Meets ANSI standards for dimensional accuracy and point geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.157 inch diameter, number 22 wire gauge sizing for precise hole specification\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2.125 inches overall for maximum rigidity\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for high-performance general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eRight hand cut with regular spiral flute and straight cylindrical shank\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for point geometry and dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for use in three-jaw chucks, keyless chucks, and quick-change drill holders accepting straight cylindrical shanks in the 0.157 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized chuck and tighten securely before operation. Ensure the drilling machine is powered off and the spindle is fully stopped before changing bits. Use appropriate cutting fluid or lubricant when drilling hard metals to extend tool life and maintain point geometry. Inspect the point for wear or chipping after extended use in production cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.157 inches (number 22 wire gauge)\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, 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\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R41\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: 5998830\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51690753786162,"sku":"5998830","price":42.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e0ec463583ad36fe1f63af9cbc54cfa.jpg?v=1788275040","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998830-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
