Built from M42 cobalt high-speed steel, it carries a gold oxide coating that reduces friction and helps extend tool life under demanding conditions. The 135-degree split point reduces walking on entry and requires no center punch on most surfaces. At 5.24 inches overall length with a 3.425-inch flute length, this bit fits standard drill chucks via its straight-cylindrical shank. The web-thinned, tapered web design lowers thrust requirements and improves chip evacuation. Licensed technicians and machinists in metal fabrication, HVAC, plumbing rough-in, and electrical work commonly reach for this grade of bit when drilling into harder stock.\u003c\/p\u003e\u003cp\u003eThe C70126 is suited for drilling aluminum and other non-ferrous and ferrous metals where a heavy-duty cobalt bit is required. The right-hand spiral flute with regular helix provides consistent chip clearance during through-hole and blind-hole drilling. It conforms to NAS 907 Type J standards, making it appropriate for aerospace and industrial MRO environments as well as commercial mechanical contracting work where dimensional precision is critical. A diameter tolerance of -0.0010 to 0.0000 inches ensures holes are held within tight limits for tapped or reamed bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for heavy-duty performance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eGold oxide coating reduces friction and improves heat resistance during cutting\u003c\/li\u003e\n\u003cli\u003e135-degree split point for fast engagement and reduced walking on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers thrust load and promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for consistent chip clearance\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for dimensional and material compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy-duty jobber-length drill bit compatible with standard straight-shank drill chucks accepting a 0.3937-inch diameter shank, suitable for use in handheld drills, drill presses, and magnetic base drills across HVAC, plumbing, electrical, and industrial fabrication applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist, pipefitter, electrician, or HVAC technician using any chuck rated for a 0.3937-inch straight shank. Ensure the chuck is fully tightened and the workpiece is securely clamped before operation. Use appropriate cutting fluid or coolant on harder ferrous materials to maintain edge life; note that coolant-through is not supported by this bit. Inspect the cutting edges for wear before each use and replace when chipping or dulling is observed to maintain hole-diameter tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.425 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.811 inches (46 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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 HSS\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: -0.0010 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: 0.7 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: C70126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698900435250,"sku":"C70126","price":28.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_4d58aa91-e7d7-42f1-8e44-e7d9723ce267.jpg?v=1788369617","url":"https:\/\/voomisupply.com\/products\/cleveland-c70126-jobber-drill-bit-10mm-cobalt-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
