Iscar 5622475 Corner Radius End Mill 1/4in 4 Flute Tialn

Product Description

The ISCAR 5622475 is a solid carbide corner radius end mill from the EFFI-S4/S6 series, engineered for both roughing and finishing operations on ferrous and hard materials. The tool features a 1/4 inch mill diameter, a 0.050 inch corner radius, and a TiAlN PVD coating that provides thermal resistance and extends tool life in demanding cuts. With four right-hand flutes in a straight configuration and an extra-long reach geometry, this end mill delivers controlled material removal in deep or hard-to-access pockets. Ultra fine grain carbide construction supports edge stability at elevated cutting speeds.

This end mill is suited for use in CNC machining centers and milling fixtures handling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The extended reach of 0.750 inches makes it appropriate for deep-pocket milling and slotting applications where standard-reach tooling cannot make contact. Single-end configuration and straight cylindrical shank allow direct mounting into collet-style toolholders and precision chucks. It is a practical choice for tool rooms, production shops, and job shops processing difficult workpiece materials.

Key Features

• 0.050 inch corner radius reduces stress concentration and prevents edge chipping on hard materials
• TiAlN PVD coating provides oxidation resistance and supports dry or semi-dry high-speed cutting
• Ultra fine grain solid carbide construction delivers edge rigidity across ferrous and superalloy applications
• Extra-long reach with 0.750 inch reach length allows access to deep pockets and complex part features
• Right-hand cutting and right-hand flute direction for standard CNC milling spindle compatibility
• Suitable for both roughing and finishing passes in a single tool setup

Compatibility

Designed for use with collet toolholders and compatible cylindrical-shank milling toolholders. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H).

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Secure the straight cylindrical shank in a clean, undamaged collet or end mill holder and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates flute wear and corner chipping. Do not exceed the recommended depth of cut or feed rate for the workpiece material and machine spindle power.
