The Best of Both Worlds

• PROMAX 4 Flute Finishing EndMill

• PROMAX 4 Flute Rougher-Finisher

The PRO-4 (Patent Pending) solid carbide hybrid cutter combines the best elements of our Finishing End Mill and our Rougher-Finisher. With 8 geometries on 4 flutes, the PRO-4 presents an entirely unique approach to common problems in high-performance machining.  

Unique Hybrid Geometry

Cutting edge chip-breakers and finishing geometry appear on either the lower or upper half of each flute. In the resulting cutting action, a chip-breaking edge on one half of the tool on one flute is followed by a finishing edge in the same region on the following flute. This geometry accomplished what other geometries attempt through unequal indexing or multiple helixes. 

• Eliminates Chatter & Vibration
