1. An arrangement for automatic working data set-up particular to each type of tool bit for driving implements adapted to various types of exchangeable tool bits, said arrangement comprising;

  • (A) data markings formed on said tool bits indicative of each type of tool bit, said data markings being arranged on a shank of each tool bit in the region serving for retention and actuating connection with the driving implement and distributed around a circumference of said tool bit;

    (B) a marking read-out device built into a tool bit receptacle of the driving implement rigidly mounted to a housing of the implement, said read-out device being aligned with the data markings when the tool bit is inserted into the driving implement, said marking read-out device generating an electric signal corresponding to a sequence of the data markings on the circumference of the shank, when there, is relative motion between the tool bit and the housing; and

    (C) an electronic evaluation arrangement for receiving the electric signal, said electronic evaluation arrangement generating appropriate adjustment orders for adjusting a drive unit of the driving implement for appropriate working parameters of the tool bit.
