High Performance 1/4" Long-Reach TiALN End Mill with .015" Corner Radius

This Canadian-made Skookum End Mill combines a compact 3/8" cutting length with a relieved neck and 4" overall length for accessing deep or obstructed features. Its .015" corner radius reinforces the cutting edges, while the special helix and variable-pitch geometry support stable, high-performance machining.

Extended Reach with Stronger Cutting Edges

The relieved neck provides additional reach below the shank while minimizing unnecessary contact with the workpiece. A .015" corner radius helps reduce corner chipping and produces a smooth internal fillet, while variable-pitch geometry helps control harmonic vibration and chatter during demanding machining operations.
