It measures 0.07 inches in diameter with an overall length of 1-11\/16 inches and a flute length of 11\/16 inches. The bit is manufactured from high speed steel with a coated finish and features a 135-degree split point for fast penetration and reduced walking on entry. A web-thinned, tapered web configuration lowers thrust requirements, making this bit well suited for production drilling applications where cycle time and hole quality matter.\u003c\/p\u003e\u003cp\u003eThis bit is built for machining environments where tight tolerances and difficult workpiece materials are the norm. The screw machine length format provides added rigidity compared to jobber-length bits, which reduces deflection in short-hole applications. It is a common choice for use in drill presses, CNC machining centers, and manual screw machines. The R41C series is rated for heavy-duty use and carries ANSI and NAS 907 designations, making it appropriate for aerospace, industrial fabrication, and precision manufacturing shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates center punching on most materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting resistance and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish extends tool life in abrasive and high-heat cuts\u003c\/li\u003e\n\u003cli\u003eScrew machine length body adds rigidity and reduces deflection in short-hole drilling\u003c\/li\u003e\n\u003cli\u003eRight hand spiral flute with 2.5xD flute-to-diameter ratio for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy-duty OEM-style drill bit for use in standard straight-shank chuck systems compatible with 0.07-inch diameter tooling.

Ensure the chuck is fully tightened and the shank is seated squarely before operation. Use appropriate cutting fluid or coolant for the workpiece material, particularly when drilling titanium, to manage heat buildup and extend tool life. Inspect the cutting edge for wear or chipping before each use and replace the bit if the split point shows signs of degradation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 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\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\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\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: 0.02 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: 5998623\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700932870450,"sku":"5998623","price":38.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3adf5fb301f44ade3ed823ef56d456f.jpg?v=1788395490","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998623-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
