Measuring 0.0625 inches (1\/16 inch) in diameter with an overall length of 1.625 inches and a flute length of 0.625 inches, this bit is built for close-tolerance work where standard jobber-length bits are too long. Constructed from high speed steel with a coated finish, it features a 135-degree split point for fast engagement and reduced walking, and a web-thinned, tapered web configuration for lower thrust and cleaner entry. It cuts in a right-hand direction with a regular spiral flute pattern.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for high-performance applications and is well suited to titanium as its primary workpiece material, making it a practical choice for aerospace, mechanical, and precision fabrication work. The screw machine length profile — shorter than a standard jobber bit — provides added rigidity and reduced deflection in drill press, CNC, and turret lathe setups. The straight-cylindrical shank fits standard three-jaw chucks without adapters. It is sold individually but requires a minimum order of 12 units per the manufacturer's packaging policy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0625 inch (1\/16 inch) diameter with screw machine length for increased rigidity\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web for cleaner hole entry and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended service life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute; rated for titanium and other demanding materials\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards; Series R40C heavy duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fit for three-jaw drill chucks accepting straight-cylindrical shanks; rated for titanium as the primary workpiece material per Series R40C specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a compatible drill chuck and verify the shank is fully seated and secured before operation. Power down or de-energize the machine tool completely before changing bits. Follow applicable ANSI machining safety standards and shop safety procedures when working with small-diameter bits, as they are susceptible to breakage under side load or excessive feed pressure. Coolant-through is not supported on this bit; use appropriate cutting fluid applied externally when drilling titanium or other hard materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 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\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\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R40C\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: 0.02 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: 5999397\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51721546105138,"sku":"5999397","price":39.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91516d249e62a44777d1cd4e418ae1b1.jpg?v=1788578714","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999397-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
