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

This Canadian-made 1/4" carbide end mill features four flutes and a 0.030" corner radius for increased cutting-edge strength and smooth transitions between floors and walls. Its ALL4 coating delivers excellent resistance to heat, abrasion and wear when machining high-temperature alloys and stainless steel.

Added Edge Strength for Demanding Materials

The 0.030" corner radius reinforces the cutting edge to help reduce chipping and extend tool life under demanding cutting conditions. Four-flute geometry supports stable material removal and a smooth finish, while the stub-length construction improves rigidity during profiling, pocketing and shoulder milling.
