Built from M42 cobalt high-speed steel, it delivers the hardness and heat resistance needed when cutting through tough materials including aluminum and other metals. The bit features a 135-degree split point that reduces walking and lowers the thrust required to start a hole. A gold oxide finish provides added lubricity and corrosion resistance. The two-flute spiral design with a web-thinned, tapered web promotes efficient chip evacuation. Machinists, fabricators, and maintenance technicians working with drill presses or hand drills rely on this bit for consistent, accurate hole production.\u003c\/p\u003e\u003cp\u003eThe C70051 is suited for industrial and production environments where standard high-speed steel bits wear prematurely. Its 9.35 mm diameter (0.3680 inch) and 5 inch overall length make it a standard jobber-length tool compatible with most drill chucks and CNC spindles. Primary workpiece material guidance from the manufacturer identifies aluminum as a target material, though the M42 cobalt grade also handles other metals encountered in general metalworking and maintenance work. The straight cylindrical shank fits conventional three-jaw drill chucks without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces skating and lowers required feed force\u003c\/li\u003e\n\u003cli\u003eGold oxide coating adds lubricity and surface protection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web improves chip clearance and reduces torque demand\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.3680 inch diameter fits standard drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit for use in drill presses, hand drills, and CNC machining spindles that accept a straight cylindrical shank in the 0.3500 to 0.4000 inch range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and maintenance technicians following standard machine shop or field drilling procedures. Secure the shank fully in the chuck and verify runout before beginning a cut. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Appropriate cutting fluid or lubricant is recommended to extend tool life when drilling ferrous materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.35 mm (0.3680 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 92.08 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3750 inches (34.92 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3680 inch\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: C70051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695476080946,"sku":"C70051","price":28.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_4c02c10b-a99d-448e-923e-bfdadcf30bf8.jpg?v=1788335495","url":"https:\/\/voomisupply.com\/products\/cleveland-c70051-cobalt-jobber-drill-bit-9-35mm-135","provider":"Voomi Supply","version":"1.0","type":"link"}
