Built from M42 cobalt high-speed steel and finished with a TiAlN coating, it delivers heat resistance and edge retention in tough materials. The 135-degree split point reduces walking and lowers thrust force at the start of a cut. The parabolic flute profile clears chips efficiently during deep-hole drilling. At 2.75 inches overall length with a 1.625-inch flute length, this is a standard jobber-length format suitable for hand-held and machine-mounted drilling operations performed by machinists and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for cutting cast iron and stainless steel in both production and maintenance environments. The straight-cylindrical shank accepts standard drill chucks without adapters. The Series 2075A is engineered for applications where conventional HSS bits lose their edge prematurely due to heat buildup or abrasive workpiece materials. It fits drill presses, CNC machining centers, and hand drills configured for straight-shank tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for high red-hardness in abrasive and stainless materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life by reducing heat transfer into the cutting edge\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for reduced thrust and self-centering entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation in deep cuts\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade drill bit for standard straight-shank drill chucks in wire gauge size 31 applications.
