Built to the M51CO series specification, it features a 27\/64 inch diameter with a 135-degree split point that reduces walking and enables self-centering entry without a center punch. The cobalt construction with gold oxide finish provides heat resistance and extended tool life when drilling hard or abrasive materials. A tapered web configuration and web-thinned geometry reduce cutting force and improve chip evacuation. This bit is suited for production shops, maintenance facilities, and any trade professional drilling into tough stock.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in metalworking, fabrication, and industrial maintenance applications where standard high-speed steel bits fall short. The 27\/64 inch straight cylindrical shank fits standard drill chucks without modification. With a 4-5\/8 inch flute length and 7-1\/4 inch overall length, it provides the reach needed for deeper holes in plate stock, structural sections, and heavy-wall tubing. The right-hand spiral flute and regular helix angle suit a broad range of materials including stainless steel, alloy steel, cast iron, brass, bronze, copper, aluminum, and reinforced plastics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material with gold oxide coating for heat and wear resistance in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web-thinned, tapered web for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003e4-5\/8 inch flute length at a 6xD ratio provides chip clearance on deeper holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, spiral flute geometry compatible with standard drill presses and hand drills\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 27\/64 inch fits common three-jaw chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eANSI standard compliant; heavy-duty grade rated for high-performance and production use\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 for standard drill press chucks, magnetic base drills, and hand-held power drills accepting a 27\/64 inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove this bit with the drill unplugged or the machine locked out per applicable safety procedures. Secure the straight shank fully in the chuck and tighten with a chuck key before operation. Use cutting fluid or coolant where the material and machine setup allow, particularly when drilling stainless steel or hardened alloys, to preserve tool life. Follow shop safety standards and wear appropriate eye protection during all drilling operations.\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: 27\/64 inch (0.4219 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\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\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 6xD\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: 27\/64 inch (0.4219 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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\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: 5996354\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51696001351986,"sku":"5996354","price":61.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_b09c0350-3720-4f26-8d08-575d8c51b04d.jpg?v=1788339737","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996354-taper-length-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
