Manufactured from high speed steel with a coated finish, this bit features a 135-degree split point and web-thinned, tapered web construction for fast penetration and reduced walking on entry. The straight-cylindrical shank seats securely in standard drill chucks. At 0.177 inches in diameter and 2-3\/16 inches overall length, it is a compact, stub-length tool designed for use in tight spaces and production drilling environments where rigidity and accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for right-hand cutting with a regular spiral flute pattern and a flute-to-diameter ratio of 2.5xD, providing efficient chip evacuation. It is rated for use on titanium as the primary workpiece material, making it well suited for aerospace, mechanical, and industrial applications where hard or tough materials are regularly encountered. Series R41C is a heavy-duty line meeting ANSI and NAS 907 specifications, appropriate for machinists, maintenance technicians, and trade professionals requiring consistent performance in production or field settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces thrust and prevents bit walking on hard materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction improves cutting efficiency and chip flow\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel with coated finish extends tool life in abrasive and tough materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity for precision hole location\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 specifications for dimensional and performance compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling titanium and similarly hard workpiece materials; fits standard drill chucks accepting straight-cylindrical shanks in the 0.177-inch diameter range.

Use cutting fluid or coolant appropriate for the workpiece material to preserve bit life, noting that this bit does not support coolant-through delivery. Follow applicable shop safety standards and machine guarding requirements when operating drill presses or CNC equipment. Inspect the cutting edges for wear or chipping before each use, particularly when drilling titanium or other high-strength alloys.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.177 inches (Wire Size: 16)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/8 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\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\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: Split\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: 0.14 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: 5998617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51697261347122,"sku":"5998617","price":51.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d23e85f5e83728a6749f1a94327decac.jpg?v=1788351000","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998617-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
