Built to Series M51CO standards, it features a 31\/64 inch (0.4844 inch decimal) diameter, a 135-degree split point for self-centering entry, and a web-thinned, tapered web configuration that reduces cutting resistance. The cobalt tool material with a gold oxide finish delivers heat resistance and edge retention in tough materials. At 7-3\/4 inches overall length with a 4-3\/4 inch flute length, this bit is suited for reaching deeper holes than standard jobber-length drills. Machinists, tool-and-die workers, and maintenance technicians working with hard or abrasive materials rely on this geometry for consistent, accurate holes.\u003c\/p\u003e\n\u003cp\u003eThis taper length drill bit is rated for use across a broad range of materials including alloy steel, carbon steel, stainless steel, hardened steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high-strength bronze, copper, nickel, nickel alloy, magnesium, magnesium alloy, reinforced plastic, graphite, and cermet. Its heavy-duty grade and high-performance classification make it appropriate for both production machining environments and repair-and-maintenance work where material hardness and hole depth present challenges to standard drill bits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material with gold oxide finish for elevated heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning enables self-centering starts without a center punch on most materials\u003c\/li\u003e\n  \u003cli\u003eTaper length body provides added reach at 7-3\/4 inches OAL compared to standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks and machine tool spindles without adapters\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 6xD flute-to-diameter ratio promotes chip evacuation in deeper holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, ANSI standard compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use taper length drill bit compatible with standard straight-shank drill chucks and spindles accepting a 31\/64 inch shank diameter.

Secure the straight shank firmly in a drill chuck or collet before operation and confirm the workpiece is properly clamped. When drilling hardened or stainless steel, use appropriate cutting fluid to manage heat and extend bit life. Inspect the cutting edges for wear before each use and replace when point geometry degrades to prevent workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M51CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 31\/64 inches (0.4844 inches decimal)\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\u003eCoating\/Finish\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 7-3\/4 inches\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: 31\/64 inches (0.4844 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 6xD\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 Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreaded Shank\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5996275\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51720772845874,"sku":"5996275","price":79.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_8a3dd396-b2eb-4037-9ca2-af118b4e8d04.jpg?v=1788568949","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996275-taper-length-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
