The 0.078-inch diameter bit features a 120-degree split point with OSG proprietary R-Thinning on the web, which reduces thrust force at entry and improves centering without a center punch. A WXL finish coating extends tool life in demanding ferrous applications. The straight-cylindrical shank seats in standard drill chucks without adapters. With a 15xD flute-to-diameter ratio, this bit reaches deep-hole applications that standard jobber-length drills cannot access.\u003c\/p\u003e\u003cp\u003eThis bit is suited for machinists, tool-and-die professionals, and maintenance technicians working in metal fabrication, aerospace, automotive, and general manufacturing environments. The extra flute length makes it appropriate for through-holes in thick stock, stacked plate, or fixtures where reach is a constraint. A right-hand spiral and two-flute configuration provide efficient chip evacuation in most metals including alloy steels, stainless, and cast iron.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material for high-heat and abrasion-resistant drilling in hard metals\u003c\/li\u003e\n\u003cli\u003eWXL finish coating for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e120-degree drill point angle for general-purpose metal entry\u003c\/li\u003e\n\u003cli\u003eProprietary R-Thinned web reduces thrust at entry and aids self-centering\u003c\/li\u003e\n\u003cli\u003e15xD flute length enables deep-reach applications beyond jobber-length capability\u003c\/li\u003e\n\u003cli\u003eSpiral flute with right-hand cutting direction for standard drill press and CNC use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose extra-length cobalt drill bit compatible with standard straight-shank drill chucks on drill presses, CNC machining centers, and handheld power drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool selection and speeds and feeds for cobalt tooling. Secure the straight-cylindrical shank fully in the chuck before operation and verify runout before drilling. Power down and lock out the machine before changing or inspecting the bit. Do not exceed the recommended speeds and feeds for the workpiece material, as cobalt bits are sensitive to overheating without coolant.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.15 inches (80.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.42 inches (36.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WXL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17502411\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736979603762,"sku":"17502411","price":59.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03cc0c9816bd10ce16919c86469ea2f2.jpg?v=1788782623","url":"https:\/\/voomisupply.com\/products\/osg-17502411-extra-length-cobalt-drill-bit-0-078-in","provider":"Voomi Supply","version":"1.0","type":"link"}
