Manufactured from M42 high-cobalt steel and finished with a gold oxide coating, this bit delivers extended tool life in tough materials. The 135-degree split point reduces walking and requires no center punch on most surfaces. At 3.39 inches overall length with a 2.047-inch spiral flute, it fits standard jobber-length toolholders. The straight-cylindrical shank seats securely in drill chucks and quick-change adapters. Web thinning reduces thrust load and improves chip evacuation, making it well suited for production drilling and precision hole placement.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized at 5 mm (0.1968 inches) and is rated heavy duty per NAS 907 Type J specification, placing it in the 0.1500 to 0.2000 inch drill diameter range. It is well suited for drilling aluminum and other non-ferrous metals, as well as general-purpose applications in steel and stainless where cobalt grade tooling is required. Machinists, tool-and-die workers, fabricators, and maintenance technicians working in shops, field, or plant environments rely on this series for consistent results in repetitive drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for increased heat and wear resistance over standard HSS bits\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts on contact without center punching and reduces thrust\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating provides lubricity and corrosion resistance during operation\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves chip flow and lowers cutting force\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix evacuates chips efficiently\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for standard drill chucks and quick-change systems accepting a straight-cylindrical shank in the 0.1969-inch shank diameter range. Primary workpiece material listed by manufacturer is aluminum; the M42 cobalt grade also supports drilling in harder ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight-cylindrical shank fully into the drill chuck before operation and verify runout before beginning a drilling cycle. Power down the machine and follow lockout\/tagout procedures before changing bits or adjusting toolholders. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life, noting this bit does not support coolant-through delivery. Ensure workpiece is clamped securely to prevent movement and avoid tip breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5 mm (0.1968 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt Steel\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 Helix\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: 3.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.047 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: 0.1969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3386 inches (34 mm)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eSpecification\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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: C70097\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697615405362,"sku":"C70097","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_693e2aa1-e82f-44c9-96e4-cec4e55058db.jpg?v=1788353457","url":"https:\/\/voomisupply.com\/products\/cleveland-c70097-5mm-cobalt-jobber-drill-bit-135-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
