Made from cobalt tool steel with a gold oxide finish, this bit handles tough materials that standard high-speed steel bits struggle with. The split point geometry at 135 degrees reduces walking and enables self-centering starts without a center punch. At 0.1610 inches in diameter (wire size 20) with a 3-3\/8 inch flute length and 5-3\/4 inch overall length, it provides extended reach for deeper holes in production and maintenance drilling environments. Licensed machinists, tool and die workers, and maintenance mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in drill presses, CNC machining centers, and hand-held power tools where a straight cylindrical shank is compatible. The taper length body offers greater reach than a jobber length bit while maintaining rigidity. The 6xD flute-to-diameter ratio and web-thinned, tapered web configuration promote efficient chip evacuation. It is well matched for work on alloy steel, stainless steel, cast iron, carbon steel, aluminum, brass, bronze, copper, nickel alloys, magnesium, hardened steel, high-strength bronze, and reinforced plastics, among other materials. Right-hand cut spiral flutes are standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool steel construction with gold oxide finish for heat and wear resistance in tough materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates walking for self-centering starts\u003c\/li\u003e\n  \u003cli\u003eTaper length body at 5-3\/4 inches overall length provides extended reach beyond standard jobber bits\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web improves chip evacuation and reduces cutting force\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 0.1610 inches diameter fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards; rated heavy-duty for demanding production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style taper length replacement drill bit for use in any drill press, machining center, or power drill accepting a straight cylindrical shank at 0.1610 inches diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists or maintenance mechanics in standard three-jaw or keyless drill chucks. Ensure the shank is fully seated and the chuck is properly tightened before operation. Use appropriate cutting fluid or coolant for the material being drilled to extend bit life, noting this bit does not support coolant-through delivery. Secure the workpiece firmly before drilling to prevent movement and bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M52CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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\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\u003c\/strong\u003e: 5-3\/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: 0.1610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\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\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: 5995688\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51703693214002,"sku":"5995688","price":37.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4685106e62ec86928ee40045de795dcc_8a74f6a5-be76-4ec4-98fc-d28ad51f284b.jpg?v=1788418096","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995688-taper-length-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
