Built to M42 cobalt steel specification, it carries a TiAlN coating that extends tool life under high heat and friction. The split point tip at 135 degrees reduces walking and enables fast penetration without a center punch on most surfaces. At 3.625 inches overall length with a 2.4375-inch flute, it fits standard drill chucks and magnetic drill setups. Machinists, pipefitters, ironworkers, and maintenance mechanics reach for this bit when cutting hard ferrous metals that wear out standard high-speed steel tooling.\u003c\/p\u003e\u003cp\u003eThe C11408 is sized to wire gauge Number 8, with a decimal diameter of 0.1990 inches, placing it in the 0.1500 to 0.2000 inch range. Primary target materials are stainless steel and cast iron, where cobalt and TiAlN coating deliver the thermal resistance needed for clean, consistent holes. Parabolic flute geometry clears chips efficiently during deep-hole drilling, reducing the need to peck repeatedly. Right-hand cutting direction is standard for conventional drill press, hand drill, and magnetic drill applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance in hard-metal drilling\u003c\/li\u003e\n\u003cli\u003eTiAlN coating reduces friction and extends edge life in stainless steel and cast iron\u003c\/li\u003e\n\u003cli\u003e135-degree split point minimizes walking and lowers feed force required\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast chip evacuation in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance at the tip\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eANSI specification compliance for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy-duty jobber drill for use in standard drill presses, hand drills, and magnetic base drills accepting straight-shank bits at 0.1990 inches diameter.

Secure the shank fully in the chuck and verify concentricity before beginning a cut. Always use appropriate cutting fluid or coolant when drilling stainless steel to manage heat buildup, even though this bit does not support through-coolant delivery. Wear ANSI-rated eye protection and secure the workpiece before drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: Number 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1990 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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 Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: 0.1990 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Cast Iron\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\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C11408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51709609443634,"sku":"C11408","price":38.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c8af5a07a6094e045f4d3bacefb9aec.jpg?v=1788458373","url":"https:\/\/voomisupply.com\/products\/cleveland-c11408-cobalt-jobber-drill-bit-wire-8-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
