Built to Series M40CO standards using M40-grade cobalt high-speed steel, it delivers superior heat and wear resistance over standard HSS bits. The 135-degree split point reduces walking and cutting pressure at entry, making it well suited for production drilling environments where accuracy and bit longevity matter. At 3-5\/16 inches overall length with a 1-15\/16-inch flute length, this short-body design provides rigidity and reduced deflection in drill press and CNC applications.\u003c\/p\u003e\u003cp\u003eThis bit is sized at 13\/32 inches (0.4062 inches decimal) with a straight-cylindrical shank of the same diameter, fitting standard drill chucks without adapters. It is built for right-hand cutting with a regular spiral and tapered web configuration. Web thinning reduces thrust requirements, which is especially useful when drilling hard metals, stainless steel, alloys, and other difficult workpiece materials. It carries an ANSI specification designation and a 2.5xD flute-to-diameter ratio. Trade machinists, tool-and-die techs, and metalworking professionals working in shop or field settings are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM40-grade cobalt construction for high heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and lowers entry cutting force\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design decreases thrust and improves chip clearance\u003c\/li\u003e\n\u003cli\u003eScrew machine length (3-5\/16 inches OAL) provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flutes and straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; rated for heavy-duty, high-performance drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit screw machine length drill bit for use in standard drill chucks, drill presses, and CNC machining centers accepting a 0.4062-inch straight-cylindrical shank.

Secure the straight-cylindrical shank fully in the chuck before operation and verify concentricity to minimize runout. Always wear appropriate PPE, including eye protection, when operating cutting tools. Follow machine manufacturer speed and feed recommendations for cobalt bits in the applicable workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 13\/32 inches (0.4062 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-15\/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: Cobalt (M40 grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4062 inches\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M40CO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5996011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699950551346,"sku":"5996011","price":28.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7_cc13aa7f-d515-4162-b401-e6852dbcdea7.jpg?v=1788383943","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996011-cobalt-drill-bit-13-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
