Built to Series M51CO specifications, it features a 13\/64-inch (0.2031-inch) diameter, a 135-degree split point for self-centering entry, and a gold oxide finish. The cobalt construction delivers elevated heat resistance and edge retention compared to standard high-speed steel, making it a reliable choice for machinists, fabricators, and maintenance trades working with hard or abrasive materials. The web-thinned, tapered web design reduces thrust and improves chip evacuation.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use on drill presses, milling machines, and hand-held power tools in both production and maintenance applications. Its straight cylindrical shank fits standard three-jaw chucks without adapters. The 3-5\/8-inch flute length and 6-inch overall length (6xD flute-to-diameter ratio) provide the reach needed for deeper hole profiles that standard-length bits cannot achieve. It is well matched to shops and trades that regularly work with tough or layered stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material with gold oxide finish for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e135-degree split point promotes self-centering and reduces walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces drilling thrust and aids chip clearance\u003c\/li\u003e\n\u003cli\u003eTaper length body at 6 inches overall length for deeper reach than jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eANSI standard construction for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, high-strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic, stainless steel, and general steel stock.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove this bit with the drill press or power tool fully powered off and the chuck key removed from the work area before securing the shank. Secure the straight cylindrical shank firmly in a properly sized three-jaw chuck to prevent slippage under load. Use appropriate cutting fluid for the workpiece material, particularly when drilling stainless steel or hardened steel, to manage heat buildup. Verify spindle speed settings match the material and diameter before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 13\/64 inches (0.2031 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: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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: 0.2031 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\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eWeight\u003c\/strong\u003e: 0.04167 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5996596\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51689888842034,"sku":"5996596","price":36.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a.jpg?v=1788265204","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996596-cobalt-drill-bit-13-64","provider":"Voomi Supply","version":"1.0","type":"link"}
