Abstract

Abstract A carrying drum has an end face and is adapted to be rotatably mounted and to be rotationaly driven. An inserted-tooth cutter comprises an adapter ring flanged to said end face and provided with at least two retainers, which are axially spaced from each other and from said end face, and with radial through openings between adjacent ones of said retainers and between said retainers and said end face. Said inserted-tooth cutter further comprises at least two axially spaced apart, coaxial toothholders, which are adapted to surround said workpiece and are secured to respective ones of said retainers and carry teeth having radially inwardly facing cutting edges.
