Built to the M40CO series specification, it features a 7\/64 inch (0.1094 inch) diameter, a 135-degree split point for self-centering starts, and a web-thinned, tapered-web construction that reduces thrust and improves chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. At 1-13\/16 inches overall length with a 13\/16 inch flute, this stub-length geometry provides added rigidity for precision work in tight spaces. It meets ANSI standards and is rated heavy duty for demanding production and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for machinists, maintenance technicians, and metalworking professionals who regularly drill stainless steel, hardened alloys, titanium, and other hard materials. The screw machine length format makes it a practical choice for drill presses, CNC machines, and hand-held operations where a shorter, stiffer bit reduces deflection. The right-hand spiral flute design pulls chips away from the cutting zone during through-hole drilling. Applications include fabrication shops, machine shops, and industrial maintenance environments that require a reliable cobalt bit for repeated hard-material work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction rated for hard and abrasive workpiece materials including stainless steel and hardened alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering entry without a center punch on most materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web design reduces drilling thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 1-13\/16 inches overall for maximum rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 2.5xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant, heavy duty grade, M40 material grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cobalt stub drill for industrial and maintenance applications requiring a 7\/64 inch diameter screw machine length bit compatible with standard straight-shank drill chucks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a drill press, CNC spindle, or keyed hand-drill chuck rated for straight-cylindrical shanks. Confirm the chuck is fully tightened and the bit is seated squarely before operation. Use appropriate cutting fluid or coolant when drilling hardened steels to preserve bit life and workpiece integrity. Follow applicable shop safety procedures and wear eye protection during all drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/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\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M40CO\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 5996005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51720170864946,"sku":"5996005","price":52.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7_3a23dcaa-a8b5-4a4c-9737-13f02b454fdd.jpg?v=1788561266","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996005-7-64-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
