It measures 11\/32 inches (0.3438 inches decimal) in diameter with a 6-1\/2 inch overall length and a 4-1\/8 inch spiral flute. The 135-degree split point geometry enables self-centering entry without a center punch on most materials, reducing walking and improving hole accuracy. The gold oxide finish indicates a cobalt steel construction suited for abrasive and hard materials that would quickly wear down standard HSS bits. Machinists, maintenance technicians, and fabricators reach for this bit when working with tougher stock.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for use on a wide range of materials including alloy steel, carbon steel, stainless steel, hardened steel, cast iron, malleable iron, brass, bronze, high-strength bronze, copper, aluminum, aluminum alloy, magnesium, magnesium alloy, nickel, nickel alloy, reinforced plastic, cermet, and graphite. It suits both manual and machine drilling setups in fabrication shops, maintenance environments, and production drilling where a taper length shank provides added reach beyond a jobber-length bit. The straight cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction with gold oxide finish for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003e4-1\/8 inch flute length at a 6xD flute-to-diameter ratio provides chip clearance in deeper holes\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, right-hand cut for standard machine and hand drill use\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 11\/32 inches fits standard three-jaw chucks\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web configuration reduces cutting resistance and heat buildup\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry for consistent dimensional performance\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 any standard drill chuck accepting an 11\/32 inch straight cylindrical shank; no coolant-through capability, so use with standard external cutting fluid application where required by the material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified maintenance technicians using a drill press, mill, or hand drill with an appropriate chuck. Secure the shank fully in the chuck and verify runout before starting the cut. Apply cutting fluid or cutting oil when drilling ferrous metals, stainless steel, or nickel alloys to manage heat and extend tool life. Do not exceed the recommended RPM for the bit diameter and material being drilled, as cobalt bits can be brittle under lateral load or excessive feed pressure.\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: 11\/32 inches (0.3438 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 6xD\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 11\/32 inches (0.3438 inches)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eTool Performance Grade\u003c\/strong\u003e: Heavy-Duty High Performance\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\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: 5996583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702611935538,"sku":"5996583","price":48.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_51b6dcd7-2be6-4fbd-a00a-a05d4e9f1fbe.jpg?v=1788412306","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996583-taper-length-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
