The BOSCH range includes rotary hammers with a motor power output of 420 to 750 Watts. The higher the power output of the machine, the larger the holes (drilling diameter) you can drill. The specified maximum diameter of your machine in the materials concrete/stone, steel and wood can be found on the packaging or in the catalogue.

However, the power output also influences how quickly you can drill: the more powerful the motor and the higher the single impact energy and the impact rate, the faster you complete your work.(Note: The number of Watts alone cannot be taken as an indicator of faster work, i.e. drilling rate; this depends essentially on the impact energy and power).
