House master
A comfortable-to-use rotary hammer from the well-known company Stern is designed for small home repairs. Thanks to its low weight of 3 kg, it can be used for long periods of time without hand fatigue. Users note that this "baby" is great for wiring in the house, as they can quickly and effortlessly ditch the channel under the wires.
Working with different types of materials
The power of the perforator is 600 watts. This, of course, is not much, since it is enough for a maximum to work with drills up to 22 mm, but it saves energy significantly. At idle, the machine is capable of 1800 revolutions, which allows you to comfortably work with soft materials such as plaster, tiles and wood. At the same time, the speed controller can change the number of revolutions (speed), thereby adapting to the type of material. To make the hole the desired depth, the device has a drilling limiter. If, during drilling, the drill is stuck in the wall, then the “reverse” function will allow you to easily release it from the hole.
Equipment
A detachable second handle is supplied with the rotary hammer. It can be rotated around the axis by 360 degrees, adjusting for more comfortable work. There are also three drills for working with concrete and a case for storing a rotary hammer. True, some owners note that the case has a rather unpleasant smell. For quick change of drills and drills, the rotary hammer has an SDS chuck, however, due to the strong beating of the working element during operation, it cannot be used for drilling metal surfaces.
