Built to M42 cobalt steel grade, this bit delivers heat resistance and edge retention well beyond standard high-speed steel tooling. The 135-degree split point reduces thrust and walking at the start of a cut, eliminating the need for a center punch on most materials. The gold oxide finish provides additional lubricity and corrosion resistance during service. With a 3-5\/8-inch overall length and a 2-7\/16-inch flute length, the C70012 fits standard drill chucks and handles typical through-hole depths in plate and structural stock.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use on aluminum, non-ferrous metals, stainless steel, and other tough alloys that generate elevated cutting heat. It suits CNC machining centers, drill presses, and hand drills used in manufacturing, HVAC fabrication, plumbing rough-in, and general trade work where a durable, precision-ground bit is required. The right-hand spiral flute evacuates chips efficiently to reduce clogging and heat buildup during production runs. Conformance to NAS 907 Type J makes it a recognized specification choice for aerospace and industrial procurement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for superior heat and wear resistance over standard HSS bits\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry thrust and minimizes drill walking without center-punching\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating adds lubricity and corrosion resistance during use and storage\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web design improves chip flow and reduces cutting force\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, right-hand cut with 2 flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J specification for use in controlled industrial and aerospace applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit jobber length drill bit for standard straight-shank drill chucks; the 13\/64-inch straight-cylindrical shank seats in 3\/8-inch or larger keyed and keyless chucks on drill presses, hand drills, and CNC spindles.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by machinists, tool and die tradespeople, or experienced trade professionals familiar with proper cutting speeds and feeds for cobalt tooling. Secure the workpiece firmly before drilling and confirm chuck jaws are fully tightened to prevent bit slippage. Do not run cobalt drill bits at speeds rated only for standard HSS tooling without adjusting feed rate accordingly, as improper speeds accelerate edge wear. Cutting fluid or mist coolant is recommended for extended production use even though this bit is not coolant-through rated.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 13\/64 inches (0.2031 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 13\/64 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\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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\u003eStandard\u003c\/strong\u003e: NAS 907 Type J\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: C70012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51702037152050,"sku":"C70012","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_79bf6e02-5762-4b90-b2be-ffebe4e9380f.jpg?v=1788408496","url":"https:\/\/voomisupply.com\/products\/cleveland-c70012-cobalt-drill-bit-13-64-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
