Built from M42 cobalt high-speed steel with a gold oxide coating, it delivers enhanced heat and wear resistance compared to standard HSS bits. The 135-degree split point reduces walking and allows drilling to begin without a center punch in many setups. With an overall length of 2.95 inches, a flute length of 1.693 inches, and a straight-cylindrical shank, this bit is sized for use in standard drill chucks and drill presses. It meets NAS 907 Type J standards and carries a heavy-duty grade rating. Licensed HVAC technicians, pipefitters, electricians, and general trade mechanics reach for cobalt bits when working through harder stock.\u003c\/p\u003e\u003cp\u003eThe C70085 is well suited for drilling aluminum and similar non-ferrous metals, though its M42 cobalt construction also handles mild steel and stainless in production and maintenance settings. The 3.8 mm diameter (0.1496 inches decimal equivalent) fits common metric hole callouts in sheet metal, tubing, and structural components encountered in mechanical, plumbing, and electrical rough-in work. The two-flute spiral design with regular spiral type provides good chip evacuation in through-hole drilling. Web-thinned construction with a tapered web reduces thrust requirements, making it practical for handheld drill use on the job site as well as bench drill press work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for extended tool life in abrasive and work-hardening materials\u003c\/li\u003e\n\u003cli\u003eGold oxide coating improves lubricity and heat resistance during cutting\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design eases entry and reduces heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw chucks without adapters\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber length drill bit for use in standard drill chucks, drill presses, and handheld power drills accepting straight-cylindrical shanks in the 0.1496-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only with the drill unplugged or the power source locked out per standard shop safety practice. Secure the workpiece firmly before drilling to prevent rotation or movement. Use cutting fluid or coolant when drilling steel to extend bit life, noting that this bit does not support coolant-through delivery. Inspect the split point for chipping before each use and replace bits that show edge damage to maintain hole quality and prevent bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.8 mm (0.1496 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.693 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2599 inches (32 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1496 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eMaterial\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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\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\u003eWeight\u003c\/strong\u003e: 0.2 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: C70085\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51723362468146,"sku":"C70085","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_3d3bd405-02a3-4f0c-97af-58a52a92b5c2.jpg?v=1788603920","url":"https:\/\/voomisupply.com\/products\/cleveland-c70085-cobalt-jobber-drill-bit-3-8-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
