Manufactured from high-speed steel with a coated finish, this bit measures 47\/64 inch (0.7344 inches) in diameter and spans 5 inches in overall length. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry resistance and improve chip evacuation. A right-hand spiral flute with a 2.5xD flute-to-diameter ratio promotes efficient cutting action. This bit is built to ANSI standards and is suited for machinists, fabricators, and maintenance technicians working with titanium and comparable materials.\u003c\/p\u003e\n\u003cp\u003eThe 5998514 is a Series R40 screw machine length bit, meaning its shorter overall length provides increased rigidity compared to jobber-length equivalents. This makes it well-suited for drill press work, CNC setups, and close-tolerance operations where runout and deflection must be minimized. The straight-cylindrical shank fits standard 3-jaw chucks and collet systems. It is appropriate for use in machine shops, mechanical contracting environments, and production-line maintenance settings where titanium and high-hardness workpieces are encountered regularly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e47\/64 inch (0.7344 inches) diameter with 118-degree standard point angle for precise entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces thrust load and improves penetration in hard materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity and reduced deflection\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 standards; rated for primary workpiece material: titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose drill bit for use in standard 3-jaw chucks and collet systems compatible with straight-cylindrical shanks in the 47\/64 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with proper speeds, feeds, and workholding practices. Always secure the workpiece firmly and ensure the chuck or collet is tightened to the manufacturer specification before operation. Wear appropriate PPE including eye protection when drilling. When working with titanium or similarly hard materials, use appropriate cutting fluid to manage heat and extend bit life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 47\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.7344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 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: Standard\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 5998514\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51707597553970,"sku":"5998514","price":80.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34cff4111cccb0106321090fea09444e.jpg?v=1788441148","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998514-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
