The bit measures 0.2188 inches (7\/32 inch) in diameter with an overall length of 2-3\/8 inches and a flute length of 1-1\/4 inches. The 135-degree split point reduces walking and allows the bit to start cleanly without a center punch on most surfaces. The M40CO series cobalt construction provides heat resistance and edge retention when drilling alloy steels, stainless steels, cast iron, and other hard workpiece materials. Licensed machinists, tool-and-die technicians, and industrial maintenance mechanics are the primary installers and users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for screw machine length applications where a shorter, stiffer profile is required to minimize deflection and maintain dimensional accuracy in production drilling. It suits drill presses, CNC machining centers, turret lathes, and screw machines. The regular spiral flute with a 2.5xD flute-to-diameter ratio clears chips efficiently at moderate feed rates. The straight-cylindrical shank seats directly in standard drill chucks without adapters. The bit meets ANSI standards and carries a heavy-duty grade designation under the M40 material grade specification, making it suitable for repetitive production environments where tool life and consistency matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with M40 material grade for drilling hard and abrasion-resistant materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirements on most work\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip evacuation and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eScrew machine length profile provides extra rigidity and reduced deflection versus jobber length bits\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant construction; meets heavy-duty grade requirements for production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit suitable for use in standard drill chucks, CNC machining centers, turret lathes, and screw machines accepting a straight-cylindrical shank in the 7\/32 inch diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified maintenance technician should install and operate this bit. De-energize and lock out any machine spindle before chucking or removing the bit. Ensure the chuck or collet is properly tightened and the shank is fully seated to prevent slippage during high-speed operation. Use appropriate cutting fluid or coolant when drilling hard materials to extend tool life and maintain dimensional accuracy, noting this bit does not support coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2188 inches (7\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/4 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M40\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eTool Performance\u003c\/strong\u003e: High Performance, 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\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: 5996002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693553549618,"sku":"5996002","price":15.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7_38ea677f-7cd0-4a8a-b1fe-c80dca23eebf.jpg?v=1788314020","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996002-cobalt-drill-bit-0-2188-in","provider":"Voomi Supply","version":"1.0","type":"link"}
