ABSTRACT:
The tool unit is for a rotating cutter head which is operating along the face to be worked on by an excavator or similar machine, with the unit being comprised of a mounting base and an upper tool member. The unit can be secured by welding at the cutter head, and the upper tool member is of knife-like cross section. The cutting edge can be brought into a predetermined operating position. The upper tool member is mounted for rotation in the mounting base of the unit. The mounting of the upper tool member is such that it can rotate or turn about an axis which is inclined or orthogonally disposed at the cutter head with respect to the direction of rotation of the unit. The tool unit is also characterized thereby that the cutting edge of the upper tool can be aligned for operation by way of the attendant cutting forces or forces of reaction.
