Description:

Abstract:

The head has a transverse groove in its leading face in which two cutting blade holders with interchangeable cutting blades are clamped by means of a set screw. After loosening of the set screw, the cutting blade holders can be radially and axially adjusted by means of adjusting screws. This enables precise positioning of the cutting blades, to eliminate unequal chip formation, and rough operation due to unequal loading of the blades.
