Abstract
Disclosed herein is 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 cutting tip inserts respectively fixed to the tip supports. Each of the cutting tip inserts has a pair of rakes inclined from the opposite side surfaces of each tip insert to the center of the thickness of each tip insert so as to define a first V-shaped groove, and a pair of flanks inclined from the opposite side surfaces of each tip insert to the center of the thickness of each tip insert so as to define a second V-shaped groove. The pair of rakes are formed in symmetry with respect to the center of the thickness of each tip insert, and the pair of flanks are also formed in symmetry with respect to the center of the thickness of each tip insert.
