  • Understanding Chip Formation in High Performance End Mills

    Destiny end mills also form a manageable "6" and "9" shaped chip by traveling down through the gullet to the core diameter of the end mill. However we have developed a rake face geometry that enables the material to curl in the outer rake face as you can see by the red arrow above. By doing this we create much less friction (and HEAT) in the tool which translates to longer tool life.
