Abstract
The invention relates to an ultrasonic vibration transducer (1) for ultrasonic drilling in building material such as concrete, stone, brick or plaster. The invention proposes constructing the ultrasonic vibration transducer (1) as a tube-like hollow body which becomes narrower in the direction of its front end (2) and providing it with an exchangeable core (14). As a result of the hollow shape, a high degree of vibration amplification is achieved; by virtue of the exchangeable core (14), the ultrasonic vibration transducer (1) can be adapted to suit different tools (13).
