Built from M6K cobalt high-speed steel and finished with OSG WXL coating, this bit delivers extended tool life in hard and abrasive materials. The 0.315-inch (8.00 mm) diameter and 10.04-inch (255 mm) overall length make it the right choice for deep-hole drilling operations in aerospace, die and mold, and general machining environments. The 120-degree standard point with R-thinned web reduces entry force and improves chip evacuation. A fast spiral flute and right-hand cutting direction round out the performance profile.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production and maintenance machining operations requiring reach beyond what a jobber-length drill can provide. The straight-cylindrical shank seats directly in standard drill chucks and collet holders without adapters. Series 1750 is positioned as a high-performance option for cutting steel, stainless steel, cast iron, and other ferrous materials where cobalt grade tooling is specified. It is used by machinists, tool-and-die makers, and maintenance mechanics working on manual lathes, drill presses, and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM6K cobalt steel construction for heat resistance and edge retention in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eWXL finish reduces friction and extends tool life in high-cycle applications\u003c\/li\u003e\n  \u003cli\u003e120-degree standard point with R-thinned web for reduced entry force and cleaner starts\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute promotes efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds core strength along the full flute length\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style extra-length drill bit for use in standard drill chucks and collet systems accepting a 0.315-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or maintenance mechanics.
