It carries a 3\/8 inch mill diameter, a 0.03 inch corner radius, and five flutes with a variable index design that reduces harmonic vibration during aggressive cuts. The AlTiCrSiN PVD coating provides thermal resistance and surface hardness suited to high-temperature alloys and hard materials. With a 4 inch overall length and extended reach geometry, this tool fits CNC machining centers and manual mills where rigidity and tool life in difficult materials are priorities. Licensed machinists and toolroom professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The short flute length of 3\/4 inch combined with a 2.125 inch reach length makes it well suited for shoulder milling, slotting, and profiling in materials that demand a high-performance submicron carbide substrate. The straight cylindrical shank with h6 tolerance ensures secure, repeatable clamping in standard collet chucks and shrink-fit toolholders. It is part of the ECI-5-VF series, which is built around a normal pitch, right-hand cutting, right-hand spiral flute configuration for consistent chip evacuation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron grain substrate for toughness in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eAlTiCrSiN PVD coating for elevated thermal and wear resistance\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius protects cutting edges and improves corner strength on part features\u003c\/li\u003e\n\u003cli\u003eExtended reach design at 2.125 inches accommodates deep shoulder and profile operations\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut configuration compatible with standard CNC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore toolholders including collet chucks and shrink-fit holders accepting a 3\/8 inch straight-cylindrical shank with h6 tolerance.
