Description

ABSTRACT:
A soil and rock drill adapter intended for coupling a rotatable drill rod to a drill bit, optionally with intermediate percussion drilling means or compressed-air drilling means, is arranged to permit the drill bit to be positioned eccentrically in relation to the longitudinal axis of the drill rod. To this end the adapter comprises two mutually connecting parts arranged one above the other and abutting each other in a plane extending at right angles to the longitudinal axis of the drill rod, and means being provided which enable two adapter parts to be adjusted relative one another between an eccentric position and a centric position relative to said axis.
