The invention relates to a tool that is intended for cyclo-palloid gear hobbing and includes a head (1) and a plurality of milling inserts (2) protruding from a front side (4) of the same. The milling inserts are mounted - suitably two by two - in chip removal units (3) that are detachably connected to the head. The individual milling insert (2) is clamped by means of a wedge (19) and a screw (20) easy to access, the wedge (19) acting tangentially against the milling insert behind which there is a robust tangential support in the form of a shoulder (56). By said wedge clamping of the milling insert, there is gained that the milling inserts can be mounted and dismounted in a simple way, as well as that each group of wedge+milling insert+tangential support can be located tangentially and thereby efficiently carry the cutting forces acting on the milling insert. In further aspects, the invention relates in addition to an insert holder as such intended for the tool, a chip removal unit in the form of an insert holder equipped with a milling insert, as well as an insert kit. |
