Benefits of High Helix Geometry:
High helix end mills are typically defined as possessing a helix greater than 30° (standard).
The helix angle determines the axial (along centerline) and radial (perpendicular to centerline) forces acted upon the mill as it removes material from the workpiece.
As the helix increases, the cutting edge length of engagement is lessened, resulting in an increased axial force component and a decreased radial force component.
Increased axial forces allow more effective chip evacuation and an improved finish on the workpiece.
Decreased radial forces reduce tool deflection and avoid tool breakage.
These features make high helix end mills suited for thin walled parts and other similarly demanding applications.
