Abstract
Tool holder has a first section adapted to be connected to a machining center and a tool holding section comprising a bore with a surface defining an inner diameter of the bore. Dispersed around the surface of the bore and at least partially embedded in the surface of the bore is a joining compound having a Young's modulus greater than a Young's modulus of the surface of the bore.

A tool holder for holding a tool having a shank with an outer diameter, the tool holder comprising:
- a first section adapted to be connected to a machining center and a tool holding section comprising a bore having a surface defining an inner diameter of the bore and having dispersed around the surface of the bore and at least partially embedded in the surface of the bore a joining compound having a Young's modulus greater than a Young's modulus of the surface of the bore;
- and
- an applicator fixed temporarily in the bore of the tool holder with the surface of the bore in a state of stress from heating the tool holder to expand the bore and allowing the bore to cool onto the applicator which causes a forceful application of the joining compound into the surface of the bore.
A tool holder for holding a tool having a shank with an outer diameter, the tool holder comprising:
- a first section adapted to be connected to a machining center;
- and
- a tool holding section comprising a bore having undergone a temporary change in an inner diameter;
- and
- a joining compound having been applied to a surface of the bore by an applicator while the inner diameter of the bore was temporarily changed and embedded in the bore by pressure between the surface of the bore and the applicator when the bore returned to its initial diameter.
