Built from M42 high-speed cobalt steel, it carries a gold oxide coating that improves lubricity and heat resistance during high-speed operation. The bit measures 2.8 mm in diameter (0.1102 inches) with an overall length of 2.4 inches and a flute length of 1.299 inches. A 135-degree split point reduces walking on entry and lowers thrust force, making it well suited for hard or work-hardened materials. The straight-cylindrical shank seats securely in standard drill chucks. This bit meets NAS 907 Type J standards and is graded heavy duty.\u003c\/p\u003e\u003cp\u003eThe C70222 is intended for use in metalworking environments where aluminum and similar non-ferrous or light alloy materials are the primary workpiece. Its regular spiral flute geometry promotes efficient chip evacuation in these materials. The two-flute configuration keeps the cutting geometry simple and easy to resharpen. Typical users include maintenance technicians, HVAC sheet-metal fabricators, plumbers drilling through framing and fixtures, and electricians boring pilot holes through metal enclosures and junction boxes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates center-punch marking on most metals\u003c\/li\u003e\n\u003cli\u003eGold oxide coating provides added lubricity and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for reduced cutting torque\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for consistent dimensional quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber-length drill bit compatible with any standard drill chuck accepting a 0.1102-inch straight-cylindrical shank, suitable for benchtop drill presses, hand drills, and CNC drilling operations in the 0.1000- to 0.1500-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, maintenance technicians, or trade professionals using a standard drill press or hand drill. Secure the shank fully in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and use cutting fluid when drilling ferrous materials to extend bit life and manage heat buildup. Do not exceed the rated speed range for the material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.8 mm (0.1102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.299 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1 inches (28 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1102 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\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\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2213\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: C70222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716290937138,"sku":"C70222","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_9cdcb415-28c0-4b12-98b8-217d97bc24e7.jpg?v=1788524051","url":"https:\/\/voomisupply.com\/products\/cleveland-c70222-jobber-drill-bit-2-8mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
