Abstract
A toolholder includes a cutting tool mounted to a head attached to a collar at a first end of the toolholder. A shank is located at a second, opposite end of the toolholder. A central cavity extends inwardly from the first end toward the shank. A passive vibration absorber assembly is disposed within the central cavity. The passive vibration absorber assembly includes an absorber body and an absorber cap attached to the absorber body. The absorber body has a first end, a second end opposite the first end, and one or more cavities formed in the second end. The one or more cavities of the absorber body are partially of wholly filled with metal or ceramic particles or powders to provide particle damping for suppressing vibration of the toolholder.
