Abstract
A tool holder includes a plurality of portions arranged in end-to-end relationship and interconnected by friction weld to form a unitary assembly subjected to a heat treatment. The portions formed of different respective materials have different mass properties and/or different chemical compositions. A front-most one of the portions constitutes a cutter head portion, and a rear-most one of the portions constitutes a mounting portion. The cutter head portion can be in the form of an unfinished blank which is subsequently machined. A third portion, e.g. of aluminum, could be provided to minimize the weight of the tool holder.

A tool holder comprising a plurality of portions arranged in end-to-end relationship and interconnected by friction weld to form a unitary assembly subjected to a heat treatment;
- the portions formed of different respective materials having at least one of:
- different mass properties and different chemical compositions;
- a front-most one of the portions constituting a cutter head portion, and a rear-most one of the portions constituting a mounting portion.
A tool holder comprising a rear mounting portion, a front cutter head portion, and an intermediate portion interconnecting the front and rear portions;
- the front, rear, and intermediate portions formed of different respective materials having different mass properties and/or different chemical compositions, and interconnected in end-to-end fashion along an axis by friction welds to form a unitary assembly.
A method of producing a tool holder, comprising the steps of:
- A) providing a plurality of portions comprised of respective materials having different mass properties and/or different chemical compositions;
- B) placing the plurality of portions in end-to-end relationship along a center axis;
- C) friction welding the plurality of portions together to form a unitary assembly, wherein a rear-most one of the portions constitutes a mounting portion and a front-most one of the portions constitutes a cutterhead;
- and
- D) heat treating the unitary assembly.
