Rotary and impact drill with dust extraction system - has suction members and uses electric drive motor cooling air in dust exhaust system

摘要

The electrically driven heavy duty rotary and impact drill is fitted with a dust extraction system, with its members designed as add-on portions. In line with the tool holder and drive spindle is supported a dust collector chamber connected by a flexible tube to a dust reservoir chamber. This reservoir is a rectangular box with a removable bag inside, which slides onto the lower part of the body, and is locked by a lever. The dust exhaust system is combined with the cooling air supply for the drive motor. Mounted inside the reservoir are auxiliary hinged flaps. The drill is fitted with a thermal protective device. The reservoir has guide portions which slide into recesses on the body of the drill, and includes sealing strips.
