Built from M6K-grade cobalt high-speed steel, this bit carries a WXL finish that extends tool life in abrasive and hard materials. The 120-degree point angle delivers clean entry geometry suited to steel, stainless, cast iron, and similar ferrous alloys. With an overall length of 6.1 inches and a 2-flute spiral flute design with fast spiral, the bit provides efficient chip evacuation in deep-hole applications. The R-thinned web reduces thrust load at entry, making it practical for manual and CNC-assisted drilling operations.\u003c\/p\u003e\u003cp\u003eThis extra-length drill bit is designed for metalworking applications where extended reach is required — including drilling through thick stock, structural sections, fabrication fixtures, and deep cross-holes. The straight cylindrical shank with a 7\/32-inch diameter fits standard drill chucks without adapters. The 3.94-inch flute length accommodates deep passes without requiring frequent bit extraction to clear chips. Machinists, tool-and-die techs, and industrial maintenance professionals working in metal fabrication, MRO, and general manufacturing are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM6K cobalt high-speed steel construction for heat and wear resistance in hard metals\u003c\/li\u003e\n\u003cli\u003eWXL finish extends cutting edge life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle for accurate self-starting entry on ferrous stock\u003c\/li\u003e\n\u003cli\u003eFast spiral flute geometry promotes chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eR-thinned, tapered web reduces push force and minimizes workpiece walking\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 OSG Series 1750 extra-length drill bit for use in standard drill chucks accepting a 7\/32-inch straight cylindrical shank, compatible with drill presses, CNC machining centers, and hand-held drilling equipment configured for right-hand rotation.\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 operations. Secure the shank fully in the drill chuck and verify runout before cutting. Always wear appropriate eye protection and secure the workpiece before drilling. Consult machine tool manufacturer guidelines for recommended feeds and speeds when drilling cobalt-rated tool steel into the target material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.1 inches (155 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.94 inches (100 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\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\u003eTool Material\u003c\/strong\u003e: Cobalt (M6K High Performance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: WXL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 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: 0.15 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: 17507711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731014189362,"sku":"17507711","price":112.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7b69afcc13b402a19fbe7ffce0809cc.jpg?v=1788725877","url":"https:\/\/voomisupply.com\/products\/osg-17507711-extra-length-cobalt-drill-bit-0-2188-in","provider":"Voomi Supply","version":"1.0","type":"link"}
