With a 3\/4 inch mill diameter, 1.625 inch length of cut, and a 0.015 inch corner radius, it delivers both roughing and finishing capability in a single tool. The 4-flute, right-hand spiral geometry combined with an AlTiN (aluminum titanium nitride) PVD coating provides extended tool life and heat resistance at elevated cutting speeds. The Weldon flat shank and short-length configuration promote rigidity and reduce deflection in aggressive cuts. This tool is installed by machinists and tool-and-die professionals operating CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThe 6676524 is suited for work in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its centercutting design allows plunge entry, expanding its application range to slotting, profiling, and pocketing operations. The H1TE series targets high-performance material removal where tool life and surface finish consistency are critical. It is compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.015 inch corner radius reduces edge chipping and extends tool life on hardened and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating delivers oxidation resistance and thermal hardness for high-speed dry or semi-dry machining\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and slip resistance in high-torque applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral with normal pitch supports balanced chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade material provides fine grain structure for improved edge strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRated for roughing and finishing in a single tool across steel, stainless, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with EM-CV Form AD and EM IN-HSK Form A toolholding systems.

Confirm shank seating depth and Weldon flat alignment before tightening set screws. Inspect collet or chuck for wear before use, as excessive runout accelerates edge wear on carbide tooling.
