Abstract

Rotating drill head with a boring bar which is swivel able by small amounts transversely to the rotational axis by fluidic means, with a base, a driven member located opposite the base, a pressure chamber arranged between the base and driven member and having a fluid inlet, and with an expanding lever gearing in a working connection with the driven member and serving for the synchronous and oppositely directed swiveling of a tool carrier and a compensating member which are constructed so as to be geometrically similar and constitute the boring bar.
