摘要

A toolholder (10) for use in a metalworking operation, with a body (105) extending along a longitudinal axis (110) and a recess (120) extending within the first end (115) of the body. Adjacent an insert pocket (125) adapted to receive a cutting insert (130) in the recess (120) is at least one wall (135) with a portion having a surface with multiple interruptions (142) to form a chip ejection segment (145). The chip ejection segment (145) may be an integral part of the toolholder body (105) or may be a discrete piece removably attached to the toolholder body. A method of imparting to a toolholder (100) such a chip ejection segment (145) is also disclosed.
