Disk cutter

A disk cutter comprising:

• 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 said base integrally therewith so that a gullet is defined between adjacent ones of said tip supports;
• and
• a plurality of sets of tip inserts respectively fixed to said tip supports;
• each of said plurality of sets of tip inserts comprising at least one pair of inclined tip inserts and one plain tip insert;
• said pair of inclined tip inserts having oppositely inclined flanks with the same transverse clearance angle and oppositely inclined rakes with the same transverse rake angle;
• each of said inclined tip inserts having an inclined cutting edge such that a leading corner in respect of rotation of said base is lower in level than a trailing corner;
• the amount of sideward projection of said leading corner from the surface of said corresponding tip support being set larger by a given amount than that of said trailing corner.
