Powerful HM dust extraction drill with a diameter of 12.0 mm for SDS-PLUS hammers, ideal for dust-free drilling in concrete. Four cutting edges arranged at a 90-degree angle prevent snagging when hitting reinforcements. Two large extraction holes ensure that no ventilation of the drill holes is necessary. The active drill head cooling allows for clean and health-conscious drilling to protect the user, without burdening the air with drilling dust. The drill is approved by BG-Bau and suitable for all vacuum cleaners with a suction hose diameter of 28 mm.
