Built from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS tooling. The 135-degree split point reduces thrust and self-centers on contact, minimizing the need for a center punch. A gold oxide coating provides additional lubricity and corrosion resistance. At 4.5 inches overall length with a 3.1875-inch flute, this bit suits a wide range of production and maintenance drilling tasks. Two spiral flutes with a web-thinned, tapered web configuration promote efficient chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling aluminum and other non-ferrous metals, though M42 cobalt construction also handles harder ferrous alloys, stainless steel, and tough exotic materials. The straight cylindrical shank measures 0.3160 inches in diameter, making it compatible with standard three-jaw drill chucks and collet holders across benchtop drill presses, magnetic drills, and handheld power drills. It is suited for job shop, MRO, aerospace fabrication, and general metalworking environments where consistent hole quality and tool longevity are priorities. The bit meets NAS 907 Type J specification, making it applicable in aerospace and defense manufacturing contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for elevated heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers and reduces feed pressure without a center punch\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating improves lubricity and surface wear resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces torque requirements and aids chip clearing\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, two-flute design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J standard for aerospace and precision machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement or production bit for use with standard drill chucks and collet systems accepting a 0.3160-inch straight cylindrical shank.

Secure the straight shank firmly in the chuck to the full depth of the chuck jaws to prevent slippage under load. Use cutting fluid or coolant appropriate to the workpiece material to extend tool life and improve hole finish. Inspect the cutting edges and split point before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.03 mm (0.3160 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (114.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3160 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt HSS\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: -0.0010 to 0.0000 inches\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: C70045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699774718258,"sku":"C70045","price":22.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_096bc465-1fc3-49ee-b514-e678065ab4a8.jpg?v=1788380764","url":"https:\/\/voomisupply.com\/products\/cleveland-c70045-jobber-drill-bit-8-03mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
