It is manufactured from M42 cobalt high-speed steel and finished with a gold oxide coating that helps reduce friction and extend tool life. The bit features a 135-degree split point for fast penetration and reduced walking on entry. With a straight-cylindrical shank and two spiral flutes in a regular helix pattern, this bit is suited for use in standard drill chucks. It is a heavy-duty grade tool designed for production and maintenance drilling applications.\u003c\/p\u003e\u003cp\u003eThis bit is intended for drilling aluminum and similar non-ferrous and softer materials where a cobalt-grade tool provides increased heat resistance and edge retention over standard high-speed steel. The overall length is 0.75 inches (19.05 mm) with a flute length of 0.125 inches and a shank length of 0.625 inches. It is built to NAS 907 Type J standards, making it appropriate for precision work in aerospace maintenance, manufacturing, and general industrial settings. Machinists, tool-and-die technicians, and maintenance professionals are the primary users of this size range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eGold oxide coating reduces friction and helps extend cutting life\u003c\/li\u003e\n\u003cli\u003e135-degree split point minimizes walking and reduces required feed pressure\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design for improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks without adapters\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for precision tolerance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement or production drill bit for wire gauge 79 applications conforming to NAS 907 Type J standards, with primary workpiece material listed as aluminum.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed in a standard drill chuck sized for a 0.0145-inch straight shank. Machinists and maintenance technicians should secure the shank fully in the chuck before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Coolant-through is not supported on this bit; apply cutting fluid externally when required by the workpiece material. Disconnect and lock out power to any drill press or machine tool before changing bits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 79\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0145 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\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\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\u003eOverall Length\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0145 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: C70212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699900318002,"sku":"C70212","price":124.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_6b539890-9d3d-4e88-82e6-376336743aa1.jpg?v=1788382856","url":"https:\/\/voomisupply.com\/products\/cleveland-c70212-jobber-drill-bit-wire-79-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
