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

This Canadian-made 1/4" carbide end mill features four flutes and a substantial 0.060" corner radius for increased cutting-edge strength 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.

Reinforced Cutting Edges for Tough Materials

The 0.060" corner radius significantly strengthens the cutting edge, helping reduce chipping during demanding machining operations. Four-flute geometry provides excellent stability and a smooth finish, while the stub-length construction improves rigidity during profiling, pocketing and shoulder milling.
