Built from M6K-grade cobalt high-speed steel with a WXL finish, this bit delivers heat and wear resistance that standard HSS bits cannot match in demanding production or maintenance environments. The 3\/8 inch (0.375 inch) diameter and 120-degree standard point angle suit a wide range of metal-cutting applications. With an overall length of approximately 9.45 inches and a flute length of approximately 6.77 inches, it reaches depths that jobber-length bits cannot. A licensed machinist, maintenance technician, or industrial tradesperson will typically install this bit into a drill press, CNC machining center, or heavy-duty hand drill with a compatible chuck.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production drilling, tool-and-die work, maintenance repair operations, and metalworking applications requiring extended reach. The right-hand cutting direction and fast spiral flute type promote efficient chip evacuation in deep-hole passes. The tapered web configuration and R-thinned web reduce entry thrust and help center the bit cleanly without a pilot hole in many setups. It is appropriate for use in ferrous metals and alloys where cobalt grades are specified over standard HSS.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM6K cobalt high-speed steel construction for elevated heat resistance in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003eWXL finish reduces friction and extends tool life compared to uncoated cobalt bits\u003c\/li\u003e\n  \u003cli\u003eExtra length design at approximately 9.45 inches overall enables deep-hole drilling beyond jobber-length reach\u003c\/li\u003e\n  \u003cli\u003e120-degree standard point angle with R-thinned, tapered web for reduced thrust and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute geometry promotes aggressive chip evacuation in deep cuts\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 3\/8 inch shank fits standard drill chucks and collet systems without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, 2-flute configuration compatible with conventional drill press and CNC spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit extra length drill bit for use in standard 3\/8 inch drill chucks, collet holders, and CNC tool holders accepting a straight-cylindrical shank of 0.3750 inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this drill bit should be performed by a qualified machinist or trained tradesperson familiar with metal-cutting tooling. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Secure the shank with the appropriate chuck key or collet torque to the tool holder manufacturer's specification before initiating a cut. When drilling deep holes, retract the bit periodically to clear chips and prevent heat buildup, particularly in stainless or high-alloy materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.45 inches (240 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.77 inches (172 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 High-Speed Steel (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 Spiral\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: 0.375 inches (3\/8 inch)\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 Configuration\u003c\/strong\u003e: Tapered, R-Thinned\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\u003eWeight\u003c\/strong\u003e: 0.2 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: 17510711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749240570162,"sku":"17510711","price":416.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b12d7fa31f419a1f1bd416c2513ef003.jpg?v=1788903500","url":"https:\/\/voomisupply.com\/products\/osg-17510711-extra-length-cobalt-drill-bit-0-375-in","provider":"Voomi Supply","version":"1.0","type":"link"}
