Built from high speed steel (HSS) with a coated finish, this bit measures 0.111 inches in diameter and carries a 135-degree split point angle for fast, accurate starts without center-punching. The overall length is 1-7\/8 inches with a 7\/8-inch flute length, making it compact and rigid for close-tolerance work. The web-thinned, tapered web construction reduces thrust force and improves chip evacuation. A straight cylindrical shank seats securely in standard drill chucks and machine collets.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling, machining, and maintenance operations where a short, stiff drill is required to minimize deflection. The Series R41C is rated for use in titanium as the primary workpiece material, making it appropriate for aerospace, precision fabrication, and industrial maintenance applications. Right-hand cut with a regular spiral flute, it is compatible with standard CNC machining centers, drill presses, and hand-held power drills running clockwise rotation. It conforms to ANSI and NAS 907 specifications and carries a 2.5xD flute-to-diameter ratio for controlled chip removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.111 inch diameter with 135-degree split point for self-centering entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eScrew machine length (1-7\/8 inches overall) provides rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRated for titanium as primary workpiece material — high performance grade\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for use in drill presses, CNC machining centers, and power hand tools accepting a straight cylindrical shank.

Secure the straight cylindrical shank fully in the drill chuck or collet before operation, and confirm the tool is locked before powering the machine. Ensure spindle rotation is set to clockwise (right-hand) before engaging the workpiece. Follow shop safety protocols and applicable ANSI machining standards when drilling titanium or other high-strength materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.111 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 34\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/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\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\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5998560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51696026353970,"sku":"5998560","price":38.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f2befe9656ce1faeea4fb31ebda52cb.jpg?v=1788339829","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998560-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
