Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit delivers extended tool life when cutting through tough materials including aluminum, steel alloys, and similar workpieces. The 135-degree split point reduces walking on entry and lowers thrust requirements at the start of a cut. At 4.92 inches overall length with a 3.189-inch flute, the C70124 conforms to NAS 907 Type J standards and fits the Series 2213 jobber-length format. It is suited for machinists, millwrights, and maintenance technicians working with hand-held or machine-mounted drill applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is primarily intended for drilling aluminum and ferrous metals in production and maintenance environments. The straight-cylindrical shank accepts standard 3-jaw drill chucks on benchtop drill presses, CNC drilling machines, and hand drills. The regular spiral flute geometry clears chips efficiently in through-hole and blind-hole operations. With a 0.3543-inch shank diameter, it seats securely in standard chuck configurations without special toolholding adapters. The heavy-duty grade designation makes it appropriate for repetitive production drilling where standard HSS bits wear prematurely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance and extended cutting life in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and decreases feed force at the start of each hole\u003c\/li\u003e\n\u003cli\u003eGold oxide finish provides additional surface hardness and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration improves chip evacuation and reduces torque load\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to NAS 907 Type J specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement or production drill bit for use in standard 3-jaw drill chucks accepting a 0.3543-inch straight shank; part of the Cleveland Series 2213 jobber-length line conforming to NAS 907 Type J.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the drill chuck and verify runout before beginning a cut. Always wear appropriate eye protection and secure the workpiece with a vise or clamp before drilling. Follow applicable shop safety procedures and machine manufacturer guidelines for feed rate and speed settings appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9 mm (0.3543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.92 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.189 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.732 inches (44 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3543 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: C70124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697629921586,"sku":"C70124","price":24.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_4ed2348d-0833-4688-8d66-08f4d5afac5f.jpg?v=1788353551","url":"https:\/\/voomisupply.com\/products\/cleveland-c70124-cobalt-jobber-drill-bit-9mm-135","provider":"Voomi Supply","version":"1.0","type":"link"}
