摘要：<p>A base piece for detachable fixture in a retaining mounting on the cutting appliance, where the chisel is fitted, crosses over into the chisel head via a shaft. The head has a lateral notch for accommodation of a plate-shaped hard metal blade. The base surface (35) of the cut (28, 29) in the head encloses an angle of less than 90 deg. with the lateral face (37) adjacent to the head's (6, 7) longitudinal axis (16) e.g. between 30 deg. and 60 deg., and pref. 45 deg. This ensures that blades are not separated from the chisel head even under considerable stress, and the chisel is more durable.</p>
