摘要

A cutting set (3) propelled by a drive gear (4) through a drift gear has cutter holders that hold cutters. The cutters are provided to the corresponding pinions arranged equidistantly around a transmission comprised of an internal gear (2). The internal gear is arranged such that a central opening is coaxial to an entrance opening (11) leading to a passage in the rack (1). One pinion is arranged on and coaxially with the drift gear.
