ABSTRACT:
Metal working tools or tool holders having a body with flat-faced surface containing insert pockets with at least two indexable inserts in each pocket are described. A tapered wedge block is positioned between each pair of inserts to wedge the inserts against the walls of the insert pocket and to separate the pair of inserts from each other. The pair of inserts have parallel cutting edges facing the leading wall. In one preferred embodiment, a pair of indexable cutter inserts are positioned in each pocket of a plural pocket face mill body. The inserts are positioned in leading and trailing positions with an intermediate wedge block to provide parallel cutting surfaces in the same direction.
