Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit delivers extended tool life when cutting through hard or abrasive materials. The 135-degree split point reduces walking on entry, allowing accurate positioning without a center punch on most surfaces. At 3.5 inches overall length with a 2.3125-inch flute, it fits standard drill chucks and magnetic drill setups used across mechanical, HVAC, and plumbing trades.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling aluminum and other metals encountered in light commercial and residential trade work. The straight cylindrical shank seats securely in 3-jaw chucks on handheld drills, drill presses, and mag-base units. The regular spiral flute geometry promotes consistent chip evacuation in through-hole drilling. It meets NAS 907 Type J standards, making it a reliable choice for contractors and tradespeople who require dimensional consistency across a job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for heat resistance and extended cutting life in hard materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eGold oxide finish provides added lubricity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web design reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard jobber-length drill bit with a 3\/16-inch straight cylindrical shank, compatible with any 3-jaw drill chuck accepting that shank diameter, including handheld drills and bench-mounted drill presses. Primary workpiece material is aluminum; suitable for other non-ferrous and ferrous metals within the capability range of M42 cobalt tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck before operation and verify chuck key is removed prior to starting the drill. Use appropriate cutting fluid or lubricant when drilling metals to reduce heat buildup and extend bit life. Wear eye protection and secure the workpiece with a clamp or vise — never hold the workpiece by hand during drilling. Inspect the cutting edges for wear before each use; a dull cobalt bit generates excess heat that can work-harden the base material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2213\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C70011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715235184946,"sku":"C70011","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_deb01bc2-47a8-4840-9ba2-b95bdc543422.jpg?v=1788510935","url":"https:\/\/voomisupply.com\/products\/cleveland-c70011-cobalt-jobber-drill-bit-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
