Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), this bit delivers extended tool life and reduced heat buildup when drilling ferrous metals. The 135-degree split point starts on contact without walking or center-punching, and the parabolic flute geometry clears chips aggressively. Overall length is 3-7\/8 inches, with a flute length of 2-5\/8 inches, and the straight shank diameter matches the bit diameter at 15\/64 inches (0.2344 inches decimal). It meets ASME B94.11M and DIN 338 standards.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, cast iron, and similar ferrous workpiece materials in heavy-duty production or maintenance applications. The Series 2075T is a recognized heavy-duty jobber drill line intended for machinists, maintenance technicians, pipefitters, and fabricators who regularly work through hard or abrasive stock. The right-hand cutting direction is compatible with all standard drill chucks and magnetic drill presses. Web thinning reduces thrust requirements, making this bit practical for hand-held drilling where feed force is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for high heat resistance in continuous metal cutting\u003c\/li\u003e\n\u003cli\u003eTiN coating extends cutting edge life and reduces friction against ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point eliminates walking and reduces center-punch requirements\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile promotes fast, efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces drilling thrust and minimizes bit deflection\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 338 standards for jobber drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel and cast iron workpieces as stated by the manufacturer. Primary workpiece materials are steel and cast iron. Straight cylindrical shank fits standard 3-jaw drill chucks across common drill press, hand drill, and magnetic base drill platforms.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, maintenance mechanics, pipefitters, and fabricators using standard drill presses, magnetic drills, or hand-held power drills. Secure the straight shank firmly in a properly sized drill chuck before operation. Use appropriate cutting fluid or coolant on the workpiece to maximize bit life when drilling steel; this bit does not support through-coolant delivery. Inspect the cutting edges for wear before each use and replace the bit when point geometry degrades to avoid workpiece damage or bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 15\/64 inches (0.2344 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\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003c\/strong\u003e: 2-5\/8 inches (2.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches (3.8750 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: 15\/64 inches (0.2344 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2500 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\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: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C16678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51722572005682,"sku":"C16678","price":29.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72ec45573fd3d9ebc084e87d2026b024_fbc307b9-10d0-426c-9454-296abf5dd77f.jpg?v=1788592981","url":"https:\/\/voomisupply.com\/products\/cleveland-c16678-cobalt-jobber-drill-15-64-in-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
