    Tool Holding Machine uses an MT5 taper rotating head so an MT5 Arbor is required to mount knives on.
    Because Circular knives vary significantly as to diameter, bore, bevel angle, and general configuration, Knife holding flanges are quoted at request. Generally Clamping Flanges run from $200 to $800.
    Customers who are currently grinding circular knives on another machine, commonly find that they can use the clamping devices they already own.
