It measures 0.213 inches in diameter (Wire Size 3) with an overall length of 2-3\/8 inches and a flute length of 1-1\/4 inches. Manufactured from high speed steel with a coated finish, this bit features a 135-degree split point and web-thinned, tapered web construction that reduces walking and thrust force on entry. The straight-cylindrical shank fits standard chucks without modification. It is intended for right-hand cutting with a regular spiral flute pattern and is rated for heavy-duty use in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for use on titanium as the primary workpiece material, making it well suited for aerospace, precision machining, and metal fabrication tasks where tool performance and dimensional accuracy are critical. The screw machine length configuration provides added rigidity compared to jobber-length bits, which is an advantage when drilling in tight setups or on drill presses and CNC equipment. The 2.5xD flute-to-diameter ratio supports efficient chip evacuation during short-depth cycles. The R41C series meets ANSI and NAS 907 specifications, which is relevant for shops working to controlled standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction improves penetration on hard materials including titanium\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body adds rigidity over standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 specification requirements for controlled-standard environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 5998543 is rated for titanium as the primary workpiece material and belongs to the R41C series. It is designed as a screw machine length replacement or production drill bit for applications requiring ANSI and NAS 907 compliant tooling in the 0.2000 to 0.2500 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed by machinists and tool-and-die professionals in drill presses, lathes, and CNC machining centers. Secure the straight-cylindrical shank firmly in the chuck or collet before operation and verify runout is within acceptable limits. When drilling titanium or other hard metals, use appropriate cutting fluid and avoid excessive feed rates that can overheat the cutting edge. Inspect the bit for wear or chipping before each use and replace when point geometry is degraded.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.213 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/4 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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2000 to 0.2500 inches\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: 0.23 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: 5998543\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702509699378,"sku":"5998543","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/813bf7cbdaac89b114ceee12022679e6.jpg?v=1788411677","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998543-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
