Abstract
A disk cutter including an annular disk-shaped base adapted to be driven about an axis of rotation; a plurality of tip supports formed along the outer circumference of the base integrally therewith so that a gullet is defined between adjacent ones of the tip supports; and a plurality of hardened cutter inserts respectively fixed to the tip supports. The base is imaginarily divided into a plurality of segments by radially extending lines. The hardened cutter inserts in each segment are arranged symmetrically with respect to a circumferential center line of the segment so that the pitches of the hardened cutter inserts on each side of the circumferential center line are stepwise increased in a direction from the circumferential center line toward the radially extending line on the same side.
