Built to Series 1750 standards, it features a 7\/16 inch (0.4375 inch) straight-cylindrical shank, a 120-degree standard point angle, and OSG WXL finish for improved heat resistance and tool life. The 2-flute spiral design with fast spiral geometry promotes efficient chip evacuation during extended-depth cuts. This is a high-performance M6K cobalt grade tool suited for production environments where standard-length drills cannot reach the required depth.\u003c\/p\u003e\u003cp\u003eThis bit is used in metalworking and fabrication applications that require drilling beyond the reach of jobber-length tooling. Typical applications include deep-hole drilling in structural steel, die components, mold bases, and heavy-plate assemblies. The extra overall length of 280 millimeters (approximately 11.02 inches) with a 200-millimeter (approximately 7.87 inch) flute length makes it appropriate for setups on drill presses, CNC machining centers, and manual milling machines where extended reach is required. It is installed and operated by machinists, toolroom technicians, and maintenance professionals working in industrial and manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt M6K material grade for performance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eWXL coating for extended wear resistance and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003eFast spiral flute geometry promotes chip clearing in deep-hole applications\u003c\/li\u003e\n\u003cli\u003eR-Thinned web reduces thrust force and improves point penetration\u003c\/li\u003e\n\u003cli\u003eTapered web configuration maintains rigidity along the full flute length\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, compatible with standard drill press and CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an extra-length replacement or production drill bit for use in standard 7\/16 inch straight-shank drill chucks and collet holders on drill presses, milling machines, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and the chuck or collet is properly cleaned before seating the shank. Confirm the shank is fully engaged in the chuck or collet to the appropriate grip depth before beginning any cut. Use appropriate cutting fluid or coolant for the workpiece material to manage heat, since this bit does not include through-coolant capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 280 mm (approximately 11.02 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 200 mm (approximately 7.87 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M6K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WXL\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: 1750\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17511611\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730453365042,"sku":"17511611","price":494.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c299f4040d85119fce02e3f3e36ad38_46054a96-c1fb-4ca9-a99a-7cf286e44714.jpg?v=1788717705","url":"https:\/\/voomisupply.com\/products\/osg-17511611-extra-length-cobalt-drill-bit-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
