The brushless EC-TEC motor requires no maintenance and makes it so robust and powerful. With extraordinarily high impact energy, the BHC 18 drills powerfully into concrete, stone and masonry. The integrated vibration damping prevents the impact energy from being transferred to your hands. For dust-free working with the drilling dust nozzle, the Bluetooth® battery pack conveniently starts a connected CLEANTEC mobile dust extractor automatically when switching on the tool.
