Manufactured from high speed steel with a coated finish, this bit measures 0.201 inches (Wire Size #7) in diameter with an overall length of 2.25 inches and a flute length of 1.1875 inches. The 135-degree split point reduces walking on entry and requires no center punch on most surfaces. The web-thinned, tapered web construction improves chip evacuation and reduces thrust during cut. Right-hand spiral flutes and a straight cylindrical shank make this bit compatible with standard drill chucks and screw machine setups.\u003c\/p\u003e\u003cp\u003eThis bit is rated for primary workpiece material of titanium, making it suitable for aerospace, HVAC fabrication, and precision mechanical assembly work where titanium fasteners or structural components are common. The screw machine length format — shorter than a jobber-length bit — provides added rigidity and reduced deflection in drill press, turret lathe, and CNC screw machine operations. The Series R41C designation and NAS 907 specification compliance indicate suitability for critical-tolerance drilling in professional and industrial environments. Sold individually, with a minimum order quantity of 12 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point for accurate self-centering entry without center punching\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces axial thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.25 inches overall) provides rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 2.5xD flute-to-diameter ratio optimized for chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 specifications for precision and heavy-duty drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-shank drill chucks in drill press, turret lathe, and CNC screw machine setups.

Ensure the machine spindle is fully stopped and de-energized before inserting or removing the bit from the chuck. Secure the shank fully in the chuck jaws to the recommended depth before initiating a cut. Use appropriate cutting fluid or coolant for titanium workpieces to manage heat buildup and extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #7\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\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\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\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: 0.2 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: 5998676\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722820157746,"sku":"5998676","price":53.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1f371865d002ffa4a0b7a08a94c5822.jpg?v=1788596384","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998676-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
