Abstract
A cutting plate for a ball-head finish miller has a support body of hard metal centered on an axis and having a pair of oppositely directed and symmetrically oriented faces each formed with a respective substantially circularly segmental recess of a predetermined depth. A pair of substantially identical and substantially circularly segmental cutting inserts are each secured to a respective one of the faces in the respective recess and each have a respective cutting layer forming a cutting edge. The inserts and their edges are symmetrical with respect to the axis and are each of a thickness substantially less than the depth of the respective recess so that each forms a chip cavity on the respective face.
