Abstract
A toolholder includes a support having an insert seat for receiving a cutting insert. The cutting insert is brought into engagement with a workpiece to remove a chip of metal from the workpiece. The toolholder includes fluid chip-breaking means for directing a stream of high velocity fluid at the chip being removed from the workpiece to break the chip into small segments. The direction of the fluid stream can be adjusted so that a single tool can be used perform a variety of cuts while optimizing the effectiveness of the fluid chip-breaking stream for each cut.
