Built from M42 cobalt high-speed steel with a gold oxide coating, this bit delivers heat resistance and extended tool life when drilling through tough or abrasive materials. The 135-degree split point reduces walking and allows the bit to self-center without a pilot hole. At 2.56 inches overall length with a 1.417-inch flute length, it fits standard jobber-length drill chucks and is suited for hand-held and bench-mounted drilling operations.\u003c\/p\u003e\u003cp\u003eThe C70079 is rated for use on aluminum as its primary workpiece material but is well-suited for a range of non-ferrous and ferrous stock encountered in HVAC fabrication, plumbing rough-in, electrical panel work, and general mechanical trades. The right-hand spiral flute clears chips efficiently during through-hole drilling. The straight-cylindrical shank seats securely in standard keyless or keyed drill chucks without slippage. Meeting NAS 907 Type J standards, this bit is appropriate for production and service environments where dimensional accuracy and repeatable results are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance and durability in demanding drilling applications\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eGold oxide coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute with web-thinned, tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for consistent dimensional quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard jobber-length drill chucks accepting a 0.1260-inch straight-cylindrical shank.

Secure the shank fully in the chuck and confirm zero runout before beginning the cut. Apply appropriate cutting fluid for the workpiece material to preserve coating life and edge sharpness. Inspect the cutting edges for wear after extended use, particularly when drilling hardened or abrasive stock.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.2 mm (0.1260 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.417 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1418 inches (29 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1260 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 Point\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\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\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\u003eGrade\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\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: C70079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51710220271922,"sku":"C70079","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_00a6b9a7-cee5-44e8-964d-8df8bada651b.jpg?v=1788464443","url":"https:\/\/voomisupply.com\/products\/cleveland-c70079-cobalt-drill-bit-3-2mm-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
