Built from M6K-grade cobalt steel with a WXL coating, it handles demanding production and maintenance applications where standard-length bits fall short. The 120-degree point angle suits a wide range of ferrous and non-ferrous materials. With a 200 mm overall length and a 138 mm flute length, this bit provides extended reach into deep-hole applications. A licensed HVAC, industrial maintenance, or mechanical contractor would typically encounter this bit in metal fabrication and equipment repair work. The right-hand spiral flute with fast spiral type evacuates chips efficiently during extended drilling operations.\u003c\/p\u003e\u003cp\u003eThis bit is suited for industrial and commercial drilling applications where deep-hole access is required. The straight-cylindrical shank with a 15\/64-inch diameter fits standard drill chucks without adapters. R-thinned web geometry at the point reduces thrust force and improves entry into harder stock. The Series 1750 designation places this in OSGs high-performance cobalt line, appropriate for use in steel, stainless steel, cast iron, and similar hard metals. Machinists, tool-and-die technicians, and industrial maintenance pros typically specify this bit for production and repair drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM6K cobalt steel construction for heat resistance and extended tool life in hard metals\u003c\/li\u003e\n\u003cli\u003eWXL coating reduces friction and improves wear resistance\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle for versatile material entry\u003c\/li\u003e\n\u003cli\u003eFast spiral flute type promotes efficient chip evacuation in deep holes\u003c\/li\u003e\n\u003cli\u003eR-thinned web reduces drilling thrust and centers the point reliably\u003c\/li\u003e\n\u003cli\u003eExtended 200 mm overall length for deep-hole reach beyond standard bit capacity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use extra length cobalt drill bit compatible with standard straight-cylindrical chuck systems accepting a 15\/64-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and industrial maintenance technicians using standard drill chucks or CNC drilling equipment. Secure the shank fully in the chuck before operation and verify runout before drilling production parts. Use appropriate cutting fluid or coolant for hard metal applications to maximize tool life. Inspect the point and flute condition before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2344 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 200 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 138 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\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: 17521011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752911864114,"sku":"17521011","price":144.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c299f4040d85119fce02e3f3e36ad38_79da87e3-4b8e-46af-9b53-5567a6e5c828.jpg?v=1788931041","url":"https:\/\/voomisupply.com\/products\/osg-17521011-cobalt-extra-length-drill-bit-0-2344-in","provider":"Voomi Supply","version":"1.0","type":"link"}
