Built from cobalt tool material, this bit handles the thermal and mechanical demands of drilling tough ferrous and non-ferrous materials. The 35\/64 inch (0.5469 inch) diameter is paired with a 135-degree notched split point that promotes self-centering entry and reduces walking on hard surfaces without a center punch. A tapered web configuration and web-thinned geometry reduce thrust requirements and improve chip evacuation. Licensed tradespeople and machinists working in fabrication, maintenance, and industrial settings will find this bit sized and constructed for productive, repeatable use.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in machine shops, fabrication facilities, and field maintenance environments where a wide range of materials must be drilled cleanly and efficiently. The 4-7\/8 inch flute length and 8-1\/4 inch overall length give the bit extra reach for deeper holes compared to a jobber-length equivalent. The spiral flute with a 6xD flute-to-diameter ratio and right-hand cut suits standard drill press, milling machine, and handheld drill motor setups. The straight shank fits directly into standard chucks without an adapter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for high heat resistance and extended life in alloy and stainless steels\u003c\/li\u003e\n  \u003cli\u003e135-degree notched split point for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eTaper length body with 4-7\/8 inch flute length for deeper reach than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration for improved chip flow and reduced drill torque\u003c\/li\u003e\n  \u003cli\u003eStraight shank (0.5469 inch diameter) for direct chuck mounting without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular spiral type for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eANSI standard construction rated for heavy-duty drill bit grade performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe M51CO series designation identifies this as a cobalt taper length drill bit compatible with standard straight-shank drill chucks.

Secure the straight shank firmly in the chuck and verify concentricity before drilling. Always match spindle speed to the workpiece material and bit diameter using published cutting speed charts for cobalt tooling. Wear appropriate eye protection and secure the workpiece properly to prevent movement during cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 35\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.5469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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: Notched Split Point\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\u003c\/strong\u003e: 4-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eTool Application\u003c\/strong\u003e: Self-Centering\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: M51CO\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: 0.5 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: 5996284\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702004089138,"sku":"5996284","price":101.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_f86f2614-6cec-4b4c-ab12-d1d27dab77e4.jpg?v=1788407994","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996284-taper-length-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
