Built from M6K-grade cobalt high-speed steel and finished with OSG WXL coating, this bit delivers extended tool life in hard and abrasive materials. It runs a 120-degree standard point angle with R-thinned web for improved self-centering and reduced thrust at drill entry. The spiral flute geometry is fast-spiral, promoting efficient chip evacuation in deep-hole operations. At 9.248 inches overall length with a 6.457-inch flute length, this bit is well-suited to production and maintenance shops running deep bores in alloy steels, stainless, and similar tough materials.\u003c\/p\u003e\u003cp\u003eThis extra-length drill bit is designed for use in CNC machining centers, drill presses, and handheld power tools requiring a straight-cylindrical shank. It is commonly applied in metalworking environments where standard jobber-length bits lack the reach needed to complete through-holes in thick stock, weldments, or structural sections. Right-hand cutting direction makes it compatible with conventional spindle rotation. Machinists, tool-and-die professionals, and maintenance technicians working in industrial or heavy fabrication settings will find this bit appropriate for high-performance drilling cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM6K cobalt construction for heat and wear resistance in hard metals\u003c\/li\u003e\n\u003cli\u003eWXL coating extends cutting life and reduces built-up edge\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle with R-thinned web for accurate entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eFast-spiral flute promotes efficient chip clearing in deep holes\u003c\/li\u003e\n\u003cli\u003eTapered web configuration and 2-flute design balanced for rigidity and chip flow\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use extra-length drill bit for straight-chuck spindles accepting a 9\/32-inch straight-cylindrical shank across compatible drill presses, machining centers, and handheld drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with metal-cutting tooling. Secure the straight-cylindrical shank fully in the chuck and verify runout before beginning a cut. Power down and de-energize the machine spindle before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection when using cobalt tooling in hard materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2812 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.252 inches (235 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.457 inches (164 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 120 degrees\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, Fast Spiral\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: Standard\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\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: 0.2 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: 17522011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730657804594,"sku":"17522011","price":289.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d00181bec3651777903360dc9d1ac8a3.jpg?v=1788720993","url":"https:\/\/voomisupply.com\/products\/osg-17522011-extra-length-cobalt-drill-bit-0-2812-in","provider":"Voomi Supply","version":"1.0","type":"link"}
