Built to M42 cobalt high-speed steel material grade, this bit delivers heat resistance and edge retention under high-speed or interrupted cutting conditions. The 135-degree split point reduces walking on entry and lowers thrust force required, making it practical for use on curved or finished surfaces. At 2.4 inches overall length with a 1.299-inch flute length, it fits standard jobber-length chucks and drill presses. A gold oxide finish adds a light corrosion barrier and helps identify cobalt grade at a glance. This bit is installed and used by machinists, pipefitters, HVAC sheet metal technicians, and general maintenance trades.\u003c\/p\u003e\n\u003cp\u003eThe C70074 is sized at 2.7 mm (0.1063 inches) diameter and is rated for drilling aluminum as its primary workpiece material, though the M42 cobalt construction also suits stainless steel, high-nickel alloys, and other work-hardening materials encountered in trade service work. The straight-cylindrical shank seats in standard keyless or keyed chucks without modification. The regular spiral flute geometry clears chips consistently in through-hole and blind-hole applications. Meets NAS 907 Type J specification for dimensional and performance standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for heat resistance and extended tool life in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers entry thrust compared to standard 118-degree geometry\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating provides light corrosion protection and cobalt-grade identification\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for consistent chip clearing in aluminum and ferrous metals\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J specification for dimensional accuracy and heavy-duty grade classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement drill bit for use in standard keyed or keyless drill chucks accepting straight-cylindrical shanks at 0.1063-inch shank diameter. Primary workpiece material rating is aluminum; M42 cobalt grade is also suited to stainless steel and work-hardening alloys. Fits drill presses, hand drills, and magnetic base drills configured for jobber-length tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified maintenance technician should verify chuck capacity and spindle speed (RPM) before use; cobalt bits perform best at reduced speeds with consistent feed pressure compared to standard HSS bits. Secure the shank fully in the chuck and confirm concentricity before cutting. Always wear appropriate eye protection and secure the workpiece before drilling. Inspect the cutting edges for chipping or wear before each use and replace if the split point shows damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.7 mm (0.1063 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1023 inches (28 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1063 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\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 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\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\u003eGrade\u003c\/strong\u003e: Heavy Duty\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\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\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: C70074\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51690937516338,"sku":"C70074","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_0caa2c44-e2c9-44d2-b56b-e1892c007234.jpg?v=1788277834","url":"https:\/\/voomisupply.com\/products\/cleveland-c70074-cobalt-jobber-drill-bit-2-7-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
