Built to M42 high-speed steel cobalt grade, this bit features a 135-degree split point that reduces walking and allows faster penetration without a center punch. The gold oxide coating provides added lubricity and heat resistance during high-speed drilling. With a 1.3 mm diameter (0.0512 inches) and a 1.5-inch overall length, the C70060 is suited for close-tolerance work where dimensional accuracy is critical. It carries a two-flute spiral configuration with a web-thinned, tapered web for improved chip evacuation and reduced thrust load at the cutting edge.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in aluminum as its primary workpiece material but performs in a range of non-ferrous and light ferrous applications common in HVAC fabrication, sheet metal work, and mechanical service environments. The straight-cylindrical shank fits standard drill chucks without adapters. Series 2213 construction meets NAS 907 Type J specification, making it appropriate for shops and field service operations that require traceable standards compliance. The right-hand spiral cut and regular spiral type are standard for conventional drill press and hand-drill applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance over standard HSS bits\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eGold oxide coating adds lubricity and extends tool life in high-speed applications\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web improves chip flow and reduces heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design supports efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for traceable, standards-compliant applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in aluminum as the primary workpiece material per Series 2213 specification.

Use appropriate cutting fluid or lubricant when drilling metal to extend bit life and maintain dimensional tolerance. Cobalt bits are brittle compared to standard HSS — avoid side-loading or flexing during use. Worn or damaged bits should be replaced rather than reground without proper grinding equipment, as split-point geometry requires precision to restore correctly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.3 mm (0.0512 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0510 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 22 mm (0.8662 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\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: -0.0005 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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 0.1 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: C70060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697680482610,"sku":"C70060","price":68.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_c31e9d5c-3790-4e6d-b3ea-4fe9f7e49880.jpg?v=1788354077","url":"https:\/\/voomisupply.com\/products\/cleveland-c70060-cobalt-jobber-drill-bit-1-3-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
