Built to Series M51CO standards, this bit measures 7\/16 inches in diameter with a 135-degree split point and a gold oxide finish. The cobalt tool material provides superior heat resistance compared to standard HSS bits, making it well suited for tough ferrous and non-ferrous materials. A web-thinned, tapered web configuration reduces thrust and promotes self-centering entry. Spiral fluting with a 6xD flute-to-diameter ratio clears chips efficiently during deep-hole drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use by machinists, maintenance technicians, fabricators, and trade professionals working with a wide range of materials. Rated for use on alloy steel, carbon steel, stainless steel, cast iron, malleable iron, hardened steel, aluminum, aluminum alloy, brass, bronze, high-strength bronze, copper, nickel, nickel alloy, magnesium, magnesium alloy, reinforced plastic, cermet, and graphite. The taper length format provides additional reach beyond standard jobber bits, making it a practical choice for through-hole work in thicker stock or where a longer flute length is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material with gold oxide finish for extended heat resistance and tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point promotes self-centering and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust requirements on tough materials\u003c\/li\u003e\n  \u003cli\u003e4-5\/8 inch flute length with 6xD ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute, straight cylindrical shank — compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; heavy-duty grade construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard straight-shank taper length drill bit compatible with any drill press, hand drill, or milling machine chuck sized to accept a 7\/16 inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and maintenance technicians using a drill press, hand drill, or milling machine. Secure the shank fully in the chuck and verify concentricity before drilling. Always use appropriate cutting fluid or coolant when drilling stainless steel, hardened steel, or other work-hardening alloys to protect tool life. Wear appropriate PPE including eye protection when operating drilling equipment.\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: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint 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: 4-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7-1\/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: 0.4375 inches\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\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\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\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: 5996365\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691387617586,"sku":"5996365","price":59.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_5523103f-cfa1-42a4-b89b-2b152b10f695.jpg?v=1788284320","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996365-7-16-inch-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
