Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit is engineered for heavy-duty drilling applications where heat and wear resistance are critical. It features a 135-degree split point for fast penetration and reduced walking on entry. The overall length is 3.5 inches, with a 2-5\/16-inch spiral flute and a straight cylindrical shank. Machinists, maintenance technicians, and metalworking professionals install this bit in drill presses and handheld power drills alike.\u003c\/p\u003e\u003cp\u003eThis bit is rated for use in aluminum as the primary workpiece material and is well suited to production and maintenance drilling in both shop and field environments. The regular spiral flute and web-thinned, tapered web design promote efficient chip evacuation and reduce thrust load during drilling. It conforms to NAS 907 Type J standards, making it appropriate for aerospace and precision manufacturing environments where dimensional accuracy and material compliance are required. Series 2213 identifies this as a standard Cleveland heavy-duty cobalt jobber line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for extended tool life in abrasive and heat-generating applications\u003c\/li\u003e\n\u003cli\u003eGold oxide coating reduces friction and provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web improves chip flow and reduces heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute with 2-5\/16-inch flute length\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for use in controlled manufacturing environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application jobber drill bit for use in standard straight-shank drill chucks; primary workpiece material rated for aluminum per manufacturer specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and maintenance technicians using standard drill presses, CNC drilling equipment, or handheld power drills with compatible straight-shank chucks. Secure the shank fully in the chuck before operation and verify drill speed is appropriate for the workpiece material and bit diameter. Do not exceed the rated capacity of the drilling equipment. Inspect the cutting edges and point geometry before each use and replace if chipping or wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute Length\u003c\/strong\u003e: 2-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1890 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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: C70145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694683717938,"sku":"C70145","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_c1bc9e97-9881-42cb-ac21-b5620fdb4330.jpg?v=1788327157","url":"https:\/\/voomisupply.com\/products\/cleveland-c70145-cobalt-jobber-drill-bit-no-12-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
