Iscar 5622959 Corner Radius End Mill 3/4 in 3 Flute Carbide

Product Description

The ISCAR 5622959 is a solid carbide corner radius end mill designed for high-performance material removal in both roughing and finishing operations. It features a 3/4 inch cutting diameter, a 0.12 inch corner radius, and three helical flutes with a variable helix geometry that reduces chatter and harmonic vibration during aggressive cuts. Part of the ECAI-H3-CF Series, this single-end tool carries a bright, uncoated finish suited to non-ferrous metal applications. It is installed by machinists and CNC operators running production or job-shop work where surface finish and tool life on aluminum, brass, and similar materials are a priority.

This end mill is intended for use in non-ferrous metal machining environments, including aluminum alloys, copper, and brass. The variable helix design and coarse pitch make it well suited for slotting, profiling, and peripheral milling where chatter suppression matters. The extended reach configuration, with a 2.25 inch reach length and 1.2 inch length of cut, accommodates deeper pockets and stepped-wall features without requiring a longer overall assembly. It mounts in a standard straight-bore toolholder accepting a 3/4 inch shank.

Key Features

• Variable helix geometry reduces chatter and improves surface finish on non-ferrous materials
• 0.12 inch corner radius protects the cutting edge and improves corner strength during profiling
• Three right-hand helical flutes with coarse pitch for efficient chip evacuation
• Extended reach design with 2.25 inch reach length suits deep-pocket and stepped-wall features
• Center-cutting capable for plunge entry without a pre-drilled hole
• Fine-grain solid carbide construction with h6 tolerance on both mill and shank diameter

Compatibility

Designed for use with standard straight-bore toolholders accepting a 3/4 inch cylindrical shank. Intended for non-ferrous metal workpiece materials as indicated by primary material code N in the ECAI-H3-CF Series specification.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before inserting or removing the end mill. Mount the shank to the full recommended grip depth in the toolholder and torque the retention system per the toolholder manufacturer specification. Confirm runout with a dial indicator before initiating a cut, as excessive runout accelerates edge wear and defeats the chatter-free geometry of this tool.
