1/4" Six-Flute ALL4 Corner-Radius End Mill

This Canadian-made 1/4" carbide end mill combines six-flute geometry with a 0.030" corner radius for productive finishing, reinforced cutting edges and smooth transitions between floors and walls. Its ALL4 coating provides exceptional resistance to heat, abrasion and wear when machining high-temperature alloys and stainless steel.

Strong Cutting Edges with a Smooth Finish

The 0.030" corner radius reinforces the cutting edge to help reduce chipping during demanding machining operations. Six-flute geometry provides additional cutting edges for efficient machining and smooth finishes, while the stub-length construction improves rigidity during profiling, finishing and shoulder milling.
