It carries a 3\/8 inch cutting diameter with a 0.02 inch corner radius, four helical flutes, and a TiAlN (AlTiN) PVD coating that extends tool life at elevated cutting temperatures. The variable helix and variable index geometry reduce harmonic chatter during aggressive passes, making this tool effective for both roughing and finishing operations in a single setup. Overall length is 3 inches with a 3\/4 inch length of cut. Installed by machinists and CNC operators in general machining and tool-and-die environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations on ferrous metals, stainless grades, cast iron, nickel-based superalloys, titanium alloys, and hardened materials. The short flute length and straight cylindrical shank make it compatible with standard collet chucks, shrink-fit holders, and hydraulic toolholders. It is a single-end design from the ISCAR ECKI-H4R-CF Chatter Free Solid Mill Ti-Turbo series, intended for high-efficiency milling on vertical and horizontal machining centers where vibration control and surface finish are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.02 inch corner radius reduces stress concentration at the cutting edge and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry suppress chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating provides heat resistance and extended tool life on hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide substrate delivers rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction with center-cutting capability for plunge entry\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with h6 tolerance for precise toolholder fit and minimal runout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard collet, shrink-fit, or hydraulic toolholders accepting a 3\/8 inch straight cylindrical shank.
