At 0.2031 inches (13\/64 inch) in diameter, it features a 135-degree split point that reduces walking and cutting force on entry. The M40CO series construction uses a cobalt-grade tool material with a coated finish to extend heat resistance and edge life during high-speed or interrupted cuts. This bit is built to a heavy-duty grade and meets ANSI standards, making it a reliable choice for machinists, maintenance technicians, and tool-and-die professionals working on production or repair operations.\u003c\/p\u003e\u003cp\u003eThe 5996054 is suited for drilling hard metals and tough workpiece materials in screw machine and general machining applications. The shorter screw machine length body provides added rigidity compared to jobber-length bits, reducing deflection in close-tolerance work. The straight-cylindrical shank allows it to seat securely in standard three-jaw chucks and collet-style tool holders on drill presses, lathes, and CNC machining centers. The regular spiral with a 2.5xD flute-to-diameter ratio promotes efficient chip evacuation across a range of feed and speed conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material (M40 grade) for superior heat resistance in hard-material drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and lowers required feed pressure\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration improves cutting efficiency and chip flow\u003c\/li\u003e\n\u003cli\u003eScrew machine length body adds rigidity and minimizes deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eCoated finish extends cutting edge life in demanding production environments\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; heavy-duty grade rated for high-performance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement or production drill bit for use in standard straight-shank drill chucks and collet holders; primary workpiece material is hard metals and alloys as specified by the M40CO series application range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with drill press, lathe, or CNC tooling practices. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Secure the straight-cylindrical shank firmly in the chuck to prevent slippage under load. Follow appropriate cutting fluid or coolant practices for the workpiece material to protect the cutting edge and manage heat buildup, noting this bit does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 13\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2031 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\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\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\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M40CO\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: 0.04167 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: 5996054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723277140274,"sku":"5996054","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7_36a5908e-fba1-4e03-9226-3c5634f19591.jpg?v=1788602529","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996054-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
