Built on the M52CO series platform, it features a 135-degree split point and a web-thinned, tapered web design that reduces walking and lowers the thrust force required at entry. The straight cylindrical shank and right-hand spiral flute are manufactured to ANSI standards. At 3.375 inches of flute length and 5.75 inches overall, this bit provides the extended reach that maintenance machinists and tool-and-die technicians need when drilling into deep or hard-to-access workpieces. Gold oxide coating improves lubricity and heat resistance during high-speed cutting operations.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling through a wide range of production and maintenance materials, including alloy steel, carbon steel, stainless steel, cast iron, malleable iron, hardened steel, nickel and nickel alloys, brass, bronze, high-strength bronze, copper, aluminum, aluminum alloy, magnesium, magnesium alloy, reinforced plastic, cermet, and graphite. The M52CO cobalt construction makes it especially appropriate in shops and field environments where heat buildup is a concern, such as prolonged drilling cycles or interrupted cuts in tough ferrous and non-ferrous stock. It is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 21 at 0.1590 inches diameter for precise small-hole work\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces entry thrust and prevents bit walking\u003c\/li\u003e\n  \u003cli\u003eCobalt tool material with gold oxide finish provides superior heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTaper length body at 5.75 inches OAL gives extended reach over jobber-length equivalents\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 0.1590 inches fits standard drill chucks without an adapter\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry; heavy-duty grade rated for high-performance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill presses, milling machines, and hand-held drill motors equipped with a chuck sized to accept a 0.1590-inch straight shank.

Secure the shank fully in the chuck before operation and confirm runout is within acceptable limits for the application. Use appropriate cutting fluid or lubricant when drilling stainless steel, hardened steel, or nickel alloys to extend tool life. Inspect the cutting edges before each use; cobalt bits can chip if subjected to impact loading or side pressure beyond their rated capacity.\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: 21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1590 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\u003eFlute Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.75 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: 0.1590 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Oxide\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\u003eTool Performance\u003c\/strong\u003e: High Performance\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: 0.042 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: 5995710\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701730607410,"sku":"5995710","price":37.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4685106e62ec86928ee40045de795dcc_c757e82a-f048-4013-b7c2-712d34c01601.jpg?v=1788404488","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995710-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
