Built from M42 cobalt high-speed steel and finished with a gold oxide coating, it delivers heat and wear resistance suited to demanding materials. The 135-degree split point reduces walking on entry and requires no center punch on most surfaces. With an overall length of 3.625 inches and a 2-7\/16-inch flute length, this bit fits standard drill chucks and magnetic drills used by machinists, maintenance techs, and production floor professionals.\u003c\/p\u003e\n\u003cp\u003eThis bit is well suited to drilling aluminum, non-ferrous metals, stainless steel, and high-strength alloys where a standard HSS bit would wear prematurely. The regular spiral flute and tapered web configuration promote efficient chip evacuation in through-hole and blind-hole operations. It conforms to NAS 907 Type J standards, making it appropriate for aerospace-grade and precision manufacturing environments. The straight-cylindrical shank seats cleanly in 3-jaw chucks and quick-change chuck systems without slippage under normal feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction provides superior heat resistance over standard M2 HSS bits\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and eliminates center-punch requirement on most metals\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and extends cutting edge life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip flow and reduces torque demand\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type J compliant for use in aerospace and precision manufacturing specifications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.1935 inches diameter fits standard 3-jaw and quick-change chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber-length drill bit for wire size 10 applications per NAS 907 Type J specification, compatible with any standard drill press, hand drill, or CNC drilling setup accepting a 0.1935-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and metalworking technicians using standard drill presses, CNC machining centers, or hand-held power drills. Ensure the chuck is fully tightened and the workpiece is securely fixtured before drilling to prevent bit deflection or breakage. Use appropriate cutting fluid or coolant for the workpiece material to maximize bit life, particularly when drilling stainless steel or high-strength alloys. Inspect the cutting edges before use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1935 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\u003eMaterial Grade\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\u003eOverall Length\u003c\/strong\u003e: 3.625 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\u003eShank Diameter\u003c\/strong\u003e: 0.1935 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003ePoint Type\u003c\/strong\u003e: Split Point, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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: 0.3 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: C70143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51711752962354,"sku":"C70143","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_3c8c3dcf-ed9b-491c-9290-2009a4255d04.jpg?v=1788479210","url":"https:\/\/voomisupply.com\/products\/cleveland-c70143-jobber-length-drill-bit-wire-10-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
