• Increased metal removal in less machining time
• Front to back helix increase for high shearing action in multiple materials.
• Chatter free machining with exceptional harmonics.
• Increased feed and speed rates with exceptional wear ability.
• For chatterless machinging of ferrous materials in slotting, profiling, or pocketing operations
• There are several styles or designs for this tool that are sufficient in many different materials.
• Design has the broadest range and performs the best in a majority of materials.
• The helix changes along the flutes which give the mill increased stability during the cutting action.
• Substantial increases in speeds can be achieved with this design which should produce more parts faster with equal to better wear ability.
