    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.

    摘要： A rotatable cutting tool has an elongate cutting tool body, which has an axial rearward end and an axial forward end, which has a socket therein. A hard cutting member affixes to the cutting tool body within the socket. The hard cutting member has an axial forward end with a superhard axial forward portion, which has a maximum transverse dimension. The hard cutting member further has a hard axial rearward portion, which has a maximum transverse dimension. The ratio of the maximum transverse dimension of the superhard axial forward portion to the maximum transverse dimension of the hard axial rearward portion ranges between about.35 and about.45.
