Multiple internal coolant holes

Unique flute geometryHigh rigidity substrate

The multiple internal through coolant system is used for improved welding resistance.The spiral arrangement of the coolant holes enables a wide range of machining applications.Especially suitable for machining difficult-to-cut materials, offering stable machining.

Flute geometry with excellent chip disposal properties for high efficiency machining. Carbide substrate with

excellent fracture resistanceallows longer tool life.

Excellent heat resistance gives long tool life even when machining difficult-to-cut materials.

1) If the depth of cut is shallow, the revolution and feed rate can be increased.2) The irregular helix flute end mill has a large effect on controlling vibration when compared to standard end mills. However, if the rigidity of

the machine or the workpiece installation is very low, then vibration can occur. In this case, please reduce the revolution and feed rate proportionately, or set a lower depth of cut.

3) For shoulder milling, climb cutting is recommended.
