ABSTRACT:
A toolholder has an insert clamp in the form of a lever that urges the top of a cutting insert into the pocket of the toolholder. The lever may be spring biased against the insert and may also be dynamically activated by rotation of the toolholder. Additionally, the lever may be on the form of a cam. A method is described of securing a cutting insert within the pocket using the lever.
