Manufactured from high speed steel with a coated finish, this bit features a 135-degree split point and web-thinned, tapered web design that reduces walking and cutting pressure at the start of each hole. The 0.199-inch (No. 8 wire gauge) diameter and compact 2.25-inch overall length make it well suited for work in tight clearances where a jobber-length bit would be impractical. The Series R41C construction meets ANSI and NAS 907 specifications, confirming dimensional and performance standards for heavy-duty shop use.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling titanium as its primary workpiece material, making it appropriate for aerospace, precision machining, and mechanical trade applications where hard or work-hardening materials are encountered. The straight-cylindrical shank seats securely in standard drill chucks and machine spindles. With a flute-to-diameter ratio of 2.5xD and a 1.1875-inch spiral flute length, it provides reliable chip evacuation during through-hole and blind-hole operations. It is sold individually but requires a minimum order quantity of 12 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design improves cutting efficiency in hard materials including titanium\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish extends tool life under heat and friction\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length of 2.25 inches overall provides rigidity and fits tight workspaces\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and CNC machine spindles\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards for heavy-duty, high-performance drill bit classification\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 involving titanium and similar hard metals; fits any standard drill chuck or spindle accepting a straight-cylindrical shank at 0.199 inches diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with drill press, CNC, or hand-drill operation. Ensure the machine spindle or chuck is fully stopped and locked out before inserting or removing the bit. Use appropriate cutting fluid or coolant to manage heat when drilling titanium or other hard metals, as this bit does not support coolant-through delivery. Secure the workpiece firmly before drilling to prevent movement and bit deflection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.199 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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: Coated\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 (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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: R41C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 12\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: 5998679\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700497514802,"sku":"5998679","price":51.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82c40d5f432d392d0dcdb8016c866545.jpg?v=1788391119","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998679-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
