Ultrasonic drilling device

Abstract

Ultrasonic drilling device (300) with a sonotrode (310) and with an ultrasonic drilling tool (320), characterized in that a mechanical interface (350) is provided at which the ultrasonic drilling tool (320) can be connected to the sonotrode (310) in a vibration-resistant and detachable manner, wherein the sonotrode (310) has a substantially cylindrical end mass (312) with an integrally formed sonotrode rod (314) which is formed concentrically to a longitudinal central axis (150) of the end mass (312) and is directed axially away from it, wherein a diameter (D E ) the final mass (312) greater than a diameter (D S ) of the sonotrode rod (314), wherein the mechanical interface (350) is arranged in the area of ​​a free end (352) of the sonotrode rod (314) formed receiving section (354) for low-loss transmission of the ultrasonic vibration (120) from the sonotrode (310) to the ultrasonic drilling tool (320).
