Built from M6K-grade cobalt with a WXL finish, it delivers increased heat and wear resistance compared to standard HSS tooling. The bit measures 0.2031 inches (13\/64 inch shank) in diameter with a 120-degree standard point angle and a fast spiral flute configuration. It is suited for machinists, maintenance technicians, and fabrication professionals who need extended reach and reliable performance in ferrous and stainless applications. The 2-flute spiral design with R-thinned, tapered web reduces thrust and improves chip evacuation on deep-hole operations.\u003c\/p\u003e\n\u003cp\u003eThe OSG 17520111 is intended for precision drilling in metalworking environments including production machining, tool rooms, and MRO applications. The extra overall length of 7.087 inches (180 mm) with a 4.724-inch (120 mm) flute length makes it appropriate for reaching recessed features or drilling through thick stock where standard-length bits fall short. Right-hand cutting direction is standard for conventional drill press, CNC, and hand-held operations. This bit does not include coolant-through capability, so external coolant or cutting fluid application is recommended for extended cuts in hard materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM6K cobalt construction provides superior heat resistance over standard HSS for drilling hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eWXL finish reduces friction and extends tool life in demanding applications\u003c\/li\u003e\n  \u003cli\u003e120-degree standard point angle suits a wide range of metalworking applications\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute with R-thinned tapered web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eExtra overall length of 7.087 inches (180 mm) enables deep-reach and extended-clearance drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use extra length drill bit for standard drill chucks and collet systems accepting a 13\/64 inch straight-cylindrical shank in Series 1750 tooling configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling professional. Secure the shank fully in the chuck or collet and verify runout before beginning any drilling operation. Always power down and de-energize the machine spindle before changing tooling. Apply appropriate cutting fluid externally, as this bit does not support coolant-through delivery, and follow facility safety protocols for chip management and eye protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 13\/64 inch (straight-cylindrical)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.087 inches (180 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.724 inches (120 mm)\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 (M6K grade)\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 (Fast)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\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\u003eWeight\u003c\/strong\u003e: 0.15 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17520111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730803097906,"sku":"17520111","price":120.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c299f4040d85119fce02e3f3e36ad38_735aad00-5a64-4b15-8a53-803acb651ca0.jpg?v=1788723108","url":"https:\/\/voomisupply.com\/products\/osg-17520111-extra-length-cobalt-drill-bit-0-2031-in","provider":"Voomi Supply","version":"1.0","type":"link"}
