Built from cobalt tool material with a gold oxide coating, it delivers increased heat resistance and extended tool life compared to standard HSS bits. The 135-degree split point promotes self-centering on contact, reducing walking and the need for a center punch. At 0.1719 inches (11\/64 inch) in diameter with a 3-3\/8 inch flute length and 5-3\/4 inch overall length, this bit suits applications requiring deeper hole penetration than a jobber-length drill provides. Machinists, tool-and-die technicians, and metalworking professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe 5996586 is suited for drilling alloy steel, carbon steel, stainless steel, hardened steel, cast iron, malleable iron, nickel and nickel alloys, brass, bronze, high-strength bronze, copper, aluminum, aluminum alloys, magnesium, magnesium alloys, graphite, cermet, and reinforced plastics. The taper length design provides added reach for deep-hole work on drill presses, milling machines, and CNC machining centers where standard jobber bits fall short. The straight cylindrical shank fits standard drill chucks and collet holders without modification.\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 longer tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eTaper length body (5-3\/4 inch OAL, 3-3\/8 inch flute) for deeper reach than jobber-length equivalents\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web configuration reduces cutting resistance on breakthrough\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; heavy-duty grade for high-performance material removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a taper length straight-shank drill bit compatible with standard drill chucks and collet holders accepting an 11\/64 inch (0.1719 inch) shank diameter.

Ensure the workpiece is securely clamped and the spindle speed is set to a value appropriate for the material and bit diameter before operation. Power down and de-energize the machine before changing bits or adjusting chuck tension. Do not exceed the rated capacity of the chuck or collet holder when securing the shank.\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\/64 inch (0.1719 inches)\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 Point\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: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular Helix)\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\/64 inch (0.1719 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\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\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: 0.04167 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: 5996586\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51721168060722,"sku":"5996586","price":32.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_74dc2183-cc0f-4000-ae0c-db4dbbf36c04.jpg?v=1788574643","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996586-taper-length-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
