Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit delivers extended tool life in demanding production and maintenance environments. It features a 135-degree split point for reduced walking and easier starting without a center punch. The straight-cylindrical shank measures 0.4528 inches in diameter, and the overall length is 5.59 inches. Two spiral flutes with a regular helix and a web-thinned, tapered web configuration promote efficient chip evacuation. Licensed tradespeople and machinists working in fabrication, mechanical contracting, and maintenance use this bit for precise, clean-entry drilling.\u003c\/p\u003e\n\u003cp\u003eThe C70130 is well suited for drilling aluminum and similar non-ferrous and ferrous metals in both shop and field settings. With a flute length of 3.7010 inches and a shank length of 1.8897 inches, it fits standard drill chucks and magnetic base drills used in mechanical and structural applications. The Series 2213 designation indicates a heavy-duty grade consistent with NAS 907 Type J specification requirements, making it appropriate for aerospace-adjacent maintenance and precision fabrication work where dimensional tolerance control is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for heat resistance and extended edge life in hard materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates walking on entry\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating provides lubricity and corrosion resistance during cutting\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip flow and reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty jobber-length drill bit in the 0.4000 to 0.5000 inch diameter range, compatible with standard straight-shank drill chucks and portable or bench-mounted drilling equipment accepting a 0.4528-inch shank.

Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation, ensuring concentricity to avoid runout. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable shop safety protocols and manufacturer cutting-speed recommendations for the workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.5 mm (0.4528 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.7010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8897 inches (48 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4528 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 Point\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: Cobalt (M42 Grade)\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: -0.0010 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\u003eSeries\u003c\/strong\u003e: 2213\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: C70130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716502356274,"sku":"C70130","price":38.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_ab365560-a492-4eb8-bb2a-734fa13b41ac.jpg?v=1788526963","url":"https:\/\/voomisupply.com\/products\/cleveland-c70130-cobalt-jobber-drill-bit-11-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
