I purchased the PE-25180 model puncher from Energomash in 2010, I still use it, it has never let me down, for all this long period of time. The rotary hammer is distinguished by its power, 1850 W, it weighs about 6 kg, is rather heavy, but believe me, due to its power, it performs the work instantly and without any difficulty.
According to the technical characteristics, I can note that it can be attributed to more professional equipment. The impact energy is 5.0 J, the idle speed is 750 rpm, it works very fast, the voltage is 230 V at 50 Hz. The largest diameter when drilling in concrete is 36 mm. The maximum number of beats per minute is about 3000, there is also a depth limiter, a handle with a fairly soft grip.The set includes 5 nozzles SDS, peak, drill, chisel. From these positions it is immediately clear that the device is powerful, and it copes with all tasks perfectly, and its quality has been checked over the years of my operation!
