High Performance Variable Index End Mills for Difficult to Machine Materials


The HY-PRO®-CARB VGx is an entire line up of variable geometry end mills designed to extend tool life and increase metal removal rates by decreasing chatter. Unequal flute spacing breaks up harmonic vibration typically created during milling, enabling cutting performance.


Unequal flute spacing

Reduces vibration from harmonic vibration, increasing life and enabling more aggressive milling.

Raised Land Configuration

Provides additional stability when taking deeper depths of cut for more consistent performance during roughing.

TiAIN Coating

Provides stable wear resistance in high temperature milling conditions.

Additional Information

When grinding or regrinding industrial cutting tools, residual grinding dust may occur. This dust may contain chemicals known to the state of California to cause cancer, birth defects, or other reproductive harm.
