ABSTRACT:
A block type cutting tool with insert blades of the throw away type, the block having pockets for mounting the inserts and clamps movable into the pockets for locking the inserts in place. Each insert includes a groove formed centrally thereof and running generally parallel to one of the locating surfaces of the pocket for engaging a tip portion of the associated clamp. The groove is wider than the tip so that locking of the clamp first causes the tip to wedge the insert into the pocket, following which the tip engages the lip of the groove to firmly draw the wedged insert against a locating surface. This arrangement more positively holds the insert against displacement when the tool is withdrawn, provides a perceptible stop indicating the clamp is fully locked, and, in cases where radial insert adjustment is provided, helps to guide the insert to prevent cocking.
