We have been owning the Soyuzmash PE 950 hammer drill for a couple of years. We took it specially so that “for centuries”, with the hope of the durability of the Russian tool. Our puncher survived repairs in several apartments and country houses (friends take it), and so far it is showing itself on the good side.
In general, the technique is harsh: powerful, vibrates strongly, there are no additional options, including a reverse. Woodwork works without problems. In concrete work, our tool has some nuances.
Recently, repairs were made in two apartments on the ground floor of a panel house built in the 70s - they were built for the Moscow Olympics, so the quality of concrete is at the highest level. Strobil the floor and walls for communications, wiring, walls under the shelves. We noticed that the metal part quickly overheats. Accordingly, the instrument should be given rest. If not allowed to cool, gear crushing may begin. After a long work, it can also begin to sparkle and, if you do not inspect the wear of the brushes (but there is no indicator), the rotor contacts can fly. But if used wisely, this hammer drill will last a long time.
pros
Powerful, reliable, indestructible
Minuses
