7.Regulating the number of rotations and hammering (Fig. 3)

This hammer drill is equipped with a built-in electronic control circuit that can adjust and regulate the number of rotations and times of hammering. This hammer drill can be used by adjusting the dial, depending upon the contents of operation, such as boring holes into fragile materials, chipping, centering, etc.

The scale ‘1’ of the dial is designed for a minimum speed with the number of 180 rotations per minute and 1,400 times of blow per minute. The scale ‘5’ is designed for a maximum speed with the number of 360 rotations per minute and 2,800 times of blow per minute.
