Abstract
Material removal tool (100), such as for forming surfaces of valve seats, includes an integral or separable reduced diameter circumferential insert housing (106) including a plurality of inserts (120) bonded thereto. The plurality of inserts (120) include cutting surfaces (122) at different axial and radial positions relative to the axis (112) of the material removal tool (100). Cutting surfaces (122) at different axial and radial positions are arranged at different angles to the axis (112), and at least one cutting surface (122) on at least one insert is at an angle of about 45 degrees relative to the axis (112). Cutting surfaces (122) can be located on one insert-type or different insert-types and can have different combinations of cutting surfaces (122). When arranged circumferentially on the insert housing (106), a N-effective material removal tool (100) is formed. Methods of machining using the N-effective material removal tool (100) is also disclosed.
