What is the variable endmill?

Unlike even shape, variable endmill is designed to reduce vibration during machining by arranging the edge unequally.
Variable endmill is divided into irregular lead angle and irregular helix angle Variable angle means the lower cutting edge of endmill and angle between edges are arranged differently.
Irregular helix angle means the helix angle of the external cutting edge is arranged differently compared to the next helix angle.
The KORLOY’s products that applied variable are Z Endmill and V Endmill.
