Built from M42 cobalt high-speed steel with a gold oxide coating, this bit delivers extended tool life and heat resistance compared to standard HSS tooling. The 135-degree split point geometry reduces walking and allows drilling to start without a center punch. At 0.0390 inches in diameter and 1.625 inches overall length, this heavy-duty bit is suited for tight-tolerance work. It meets NAS 907 Type J standards and is installed by machinists, maintenance technicians, and trade professionals who require consistent hole quality in challenging materials.\u003c\/p\u003e\u003cp\u003eThis bit is designed for right-hand cutting with a regular spiral flute and a straight-cylindrical shank. Its primary application is drilling aluminum, though the M42 cobalt construction also handles stainless steel, high-nickel alloys, and other abrasion-resistant metals. The web-thinned, tapered web configuration reduces thrust requirements and improves chip evacuation. Typical use cases include sheet metal work, fixture fabrication, and production drilling where wire gauge hole sizes are required. This bit is sold individually but carries a minimum order quantity of 12 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eGold oxide coating improves lubricity and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web improves chip evacuation during drilling\u003c\/li\u003e\n\u003cli\u003eNAS 907 Type J compliant for use in aerospace and precision manufacturing environments\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber length replacement drill bit for applications requiring wire gauge size 61 (0.0390 inches) holes, compatible with standard drill chucks accepting straight-cylindrical shanks of 0.0390 inches in diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck. Ensure the chuck and spindle are rated for the shank diameter before use. Use appropriate cutting fluid or lubricant when drilling metals to manage heat buildup, particularly in stainless or high-alloy workpieces. Inspect the cutting edge before each use and replace bits showing signs of chipping or excessive wear to maintain hole tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0390 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\u003eOverall Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0390 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.9375 inches\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\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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\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: C70194\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51714260566322,"sku":"C70194","price":59.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_6ab57513-505e-414c-aa9e-0b3c113a3fd6.jpg?v=1788498433","url":"https:\/\/voomisupply.com\/products\/cleveland-c70194-jobber-drill-bit-size-61-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
