Abstract: A rotary chipping head assembly having a rotatable head member provided with a peripheral V-shaped seat having planar walls extending parallel to the axis of rotation of the head member and which fittedly receives a chipping knife the root section of which has flat faces which engage the flat walls of the V-shaped seat. A clamp secured to the head member bears against the root section to maintain the knife in the seat. One of the flat faces of the root section of the knife has a parallel sided key way extending perpendicular to the axis of rotation of the head which receives the head of a bolt, the shank of which rotatably fits in a bore opening out of the confronting wall of the V-shaped seat. The bolt head, which serves as a key to prevent lateral displacement of the chipping knife, is in the form of a regular polygon having an even number of side faces and has its geometric center offset from the axis of the shank so as to enable lateral adjustment of the chipping knife.
