ABSTRACT Grooves are formed in an insertion end of a working tool, such as a tool bit, chisel bit, and the like, by pivoting a grooving tool about a pivot axis extending perpendicularly to the axis of the insertion end. By pivoting the grooving tool about the pivot axis, it moves along the axial direction of the insertion end forming the grooves. A plurality of the grooving tools can be ganged together and moved by a single drive unit for simultaneously forming angularly spaced grooves in the insertion end.
