Comparison of vibration impact of an impact drill on the human body under different working conditions

Vibrations in Physical Systems

Currently there is a wide range of different kinds of power tools on the market. In the case of impact drills the major threat to the user’s health are vibration and acoustic impacts. Knowing that the actual drilling conditions may vary significantly from standardized conditions. It is important to determine the actual maximum level of dangerous factors present during drilling. Furthermore, it is also very important to link that factors to the conditions in which they occur. Among many factors affecting the level of vibration of an impact drill, change of the working position, the length of the drill bit and the diameter of the drill bit were verified in this paper. Verification was based on a comparison of vector-weighted mean values of acceleration of vibrations RMS a registered on the handles of the impact drill, while drilling in concrete, under different working conditions.
