Shims indicated * are not included with the toolholder. To change insert thickness, please purchase it separately. When using inserts whose corner-R(RE) is greater than 1.6 mm, additional modifications to the shim are necessary in order to prevent workpiece and shim from interfering each other. The insert with WF chipbreaker is not applicable for DDHN type toolholder. Wrench (FT-15) is sold separately.
