ABSTRACT:
For use with an indexable metal cutting tool, an improved holder assembly is disclosed which functions to maintain the position of an indexable insert during operation of the tool. More particularly, a holder assembly is described which includes a support member, connected to the cutter body of the tool, which includes a platform and a threaded aperture disposed normal to the plane of the platform. The latter includes a plurality of keys extending from the plane of the platform. A planar indexable insert having an aperture disposed normal to the planar surfaces thereof is disposed in abutting relationship with the platform of the support member, such that the apertures therein are in register. In addition, the planar surface of the indexable insert which is in abutting relationship with the platform includes receiving grooves which are adapted to be interengaged with the keys of the support member. The indexable insert is maintained in abutting relationship with the platform by a screw which extends through the registered apertures and is threadably engaged in said support member. The interengagement between the keys and the grooves of the support member and insert function to restrict unwanted rotational movement of the insert about the axis of the screw during use of the cutter.
