Built from M42 cobalt steel, this bit delivers superior heat and wear resistance, making it a dependable choice for production drilling in tough materials. It features a 135-degree split point for fast penetration and reduced walking without a center punch, and a gold oxide coating that further improves surface hardness and lubricity. The wire gauge size is No. 9, with a decimal diameter of 0.196 inches, and the overall length is 3-5\/8 inches. Installation and use are appropriate for machining shops, fabrication environments, and field trade professionals working with metal substrates.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for aluminum as a primary workpiece material and is well-suited for general-purpose metal drilling where a cobalt-grade, heavy-duty bit is required. The spiral flute design evacuates chips efficiently in through-hole and blind-hole drilling scenarios. The straight-cylindrical shank with a diameter of 0.196 inches seats directly into standard drill chucks found on drill presses, hand drills, and CNC equipment. The bit conforms to NAS 907 Type J specification, which is a common aerospace and industrial procurement standard for jobber-length drills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for extended tool life in abrasive and high-heat drilling conditions\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and eliminates the need for center punching\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating improves lubricity and surface hardness\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with web-thinned, tapered web for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length drill bit for use with standard drill chucks accepting a 0.196-inch straight-cylindrical shank.

Secure the straight shank fully in the chuck and verify concentricity before drilling under load. Use appropriate cutting fluid or coolant when drilling steel or other ferrous materials to extend tool life, noting that this bit does not support coolant-through delivery. Inspect the cutting edges for wear or chipping before each use, and replace when the split point shows signs of dulling to maintain hole-size accuracy within the stated tolerance of -0.0007 to 0.0000 inches.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1960 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\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\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\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-7\/16 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: 0.1960 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\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\u003eCoolant Through\u003c\/strong\u003e: No\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\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: C70142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51723402936626,"sku":"C70142","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_7d29b6fd-ee60-4525-ac6a-86b722180503.jpg?v=1788604477","url":"https:\/\/voomisupply.com\/products\/cleveland-c70142-cobalt-jobber-drill-bit-no-9-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
