Built from cobalt high-speed steel in material grade M6K, this bit carries a WXL finish and features a spiral flute with a fast spiral type for efficient chip evacuation. The straight-cylindrical shank measures 0.3937 inches in diameter, matching the bit diameter for straightforward chuck mounting. A 120-degree standard point angle provides stable entry on a range of workpiece materials. Professional machinists and metalworking tradespeople install this bit in drill presses, CNC machining centers, and manual milling setups where extended reach is required.\u003c\/p\u003e\n\u003cp\u003eThe OSG 8623300 Series 1750 extra length drill bit is suited for production and maintenance machining environments where deep-hole drilling in metals is routine. The extended flute length of approximately 9.055 inches allows drilling operations that would otherwise require step drilling or specialized equipment. Right-hand cutting direction is standard for conventional drill press and machining center spindles. The R-thinned web and tapered web configuration reduce thrust force at the cutting tip, which is especially valuable during deep-hole entry into steel, stainless, and other ferrous alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt M6K material grade for elevated heat and wear resistance in ferrous metals\u003c\/li\u003e\n  \u003cli\u003eWXL finish reduces friction and extends tool life in high-performance drilling operations\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute promotes aggressive chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eR-thinned, tapered web reduces cutting thrust and improves drill entry stability\u003c\/li\u003e\n  \u003cli\u003eExtra overall length of approximately 11.811 inches reaches depths impossible with standard jobber bits\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.000 to -0.022 mm for precise hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for applications requiring a 0.3937-inch (10 mm) diameter extra length drill bit with a straight-cylindrical shank compatible with standard drill chucks and collet systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank fully in a drill chuck or collet rated for the spindle speed being used, and verify the bit runs true before engaging the workpiece. De-energize and lock out the machine before changing tooling per standard OSHA lockout\/tagout procedures. Coolant-through is not supported on this bit, so apply external cutting fluid appropriate for the workpiece material to manage heat during deep-hole drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 300.00 mm (approximately 11.811 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 230.00 mm (approximately 9.055 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\u003eTool Material\u003c\/strong\u003e: Cobalt High-Speed Steel\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\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\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 8623300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749588468018,"sku":"8623300","price":425.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c299f4040d85119fce02e3f3e36ad38_71e48ea3-4793-4440-8e32-d176b171bcc2.jpg?v=1788908019","url":"https:\/\/voomisupply.com\/products\/osg-8623300-extra-length-cobalt-drill-bit-0-3937-in","provider":"Voomi Supply","version":"1.0","type":"link"}
