摘要

The device has a milling base plate (5) to which profile plates are attached in a specific order, where the profile plates are limited by two locking ring disks. Chisels e.g. flat chisels, are directly assembled in the profile plates. Spacer rings are attached between the profile plates. Grooves (8) of the profile plates enable shifting of the plates when the profile plates reach the disk.
