Built to NAS 907 Type J standards, it carries an M42 cobalt steel construction with a gold oxide coating that provides heat and wear resistance during high-speed cutting. The 135-degree split point starts on contact without a center punch, reducing walking and setup time. At 2.09 inches overall length with a 1.063-inch flute, this is a compact, heavy-duty bit suited for close-tolerance work. Licensed HVAC, plumbing, electrical, and mechanical trades installers keep these on hand for sheet metal, brackets, and equipment mounting applications.\u003c\/p\u003e\u003cp\u003eThe C70070 is intended for drilling aluminum and other non-ferrous metals as its primary workpiece material, though the M42 cobalt grade also handles harder ferrous materials in general shop and field use. The straight-cylindrical shank fits standard drill chucks without adapters. Its regular spiral and two-flute geometry provide good chip evacuation in through-hole and blind-hole operations. This bit is sold individually and is well suited to service vans, tool cribs, and production setups where precise small-diameter holes are required in metal components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction rated as heavy duty grade for extended tool life in tough materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates the need for center-punching before drilling\u003c\/li\u003e\n\u003cli\u003eGold oxide coating provides lubricity and heat resistance during prolonged cutting cycles\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n\u003cli\u003eNAS 907 Type J specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without special adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber length drill bit suitable for use in standard keyed or keyless drill chucks accepting a 0.0906-inch straight-cylindrical shank.

Secure the workpiece fully before drilling to prevent movement and tool breakage. Always wear appropriate eye protection and follow applicable OSHA and shop safety requirements when operating cutting tools. Do not exceed the recommended RPM range for the material being drilled, and allow adequate chip clearance when drilling deep holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 2.3 mm (0.0906 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0906 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0236 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt (M42)\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: -0.0005 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\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\u003eGrade\u003c\/strong\u003e: Heavy Duty\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\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: C70070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51709712007474,"sku":"C70070","price":58.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_65a37f36-b8e0-4c27-a5da-dca60203c53b.jpg?v=1788459450","url":"https:\/\/voomisupply.com\/products\/cleveland-c70070-jobber-drill-bit-2-3-mm-cobalt-135","provider":"Voomi Supply","version":"1.0","type":"link"}
