Built from cobalt tool material, it delivers superior heat resistance and edge retention compared to standard high-speed steel bits. The 135-degree notched point reduces walking and improves self-centering on contact, while the web-thinned, tapered web configuration reduces thrust load during entry. At 0.6875 inches in diameter with an overall length of 9.25 inches and a flute length of 5.375 inches, this bit is suited for deeper hole applications where standard-length bits fall short. Right-hand spiral flutes evacuate chips efficiently throughout the cut.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in industrial and trade shop environments where ferrous and non-ferrous materials are drilled regularly. The cobalt construction and heavy-duty grade rating make it well-suited for production drilling, maintenance work, and fabrication tasks where tool life and consistent performance under heat are priorities. A straight shank provides compatibility with standard drill chucks without requiring a morse taper adapter. The taper length body gives additional reach for deeper through-holes in plate stock, structural sections, and similar workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for extended heat resistance and longer tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree notched split point promotes self-centering and reduces the need for a center punch on most surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces axial thrust and cutting effort\u003c\/li\u003e\n  \u003cli\u003eTaper length body at 9.25 inches overall with 5.375-inch flute length for deeper hole reach\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight shank at 0.6875 inches diameter fits standard drill chucks and press collets\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; heavy-duty grade rating for demanding production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 5996580 is designed for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel, per Series M51CO specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit should be performed by a qualified machinist or skilled tradesperson familiar with drill press, milling machine, or hand drill operation. Secure the straight shank firmly in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and ensure the workpiece is clamped or fixtured securely before starting the cut. Do not exceed the recommended feed and speed parameters for the material being drilled, and apply cutting fluid when drilling hardened steel or stainless steel to extend tool life and maintain hole quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.375 inches\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\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6875 inches\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\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: 5996580\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709756670258,"sku":"5996580","price":142.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_17379d89-291e-4caf-8256-2524535c92d2.jpg?v=1788460045","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996580-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
