The 20 mm shank is a standard today in the EDM business, all types of shanks with diameter 20 on
the market will fit on our MTS65 mechanical shank holder in addition to our own line of shanks
MTS20. The need to manufacture great numbers of small electrodes, often of low value, gave us the
idea to develop a new line of aluminum shank holder to keep their cost as low as possible so that the
electrode can be left on the holder on which it has been manufactured for later use at minimal cost.
Integral copper shanks with inserted double reference pin are available in different diameters, allowing
the customer to directly machine the electrode obtaining maximum precision and rigidity at the lowest
