Weighing only 3.1 kg, the TE 3-M rotary hammer drill is a lightweight tool used for medium-duty drilling work in concrete and masonry. A corded tool in classic pistol-grip design, the rotary hammer drill also features a chiselling function, thus making it an all-rounder. Moreover, a dust-collection device was developed specifically for this model, which protects the user from the drilling dust generated, especially when working overhead, as well as a quick-release chuck, enabling a quick exchange of drill bits.
