I bought this pneumatic hammer to finally be able to drill holes in my block of flats without connecting always heavy equipment. The drill is super effective through the concrete and you have hardly any strength. The supplied drill bits are not bad, but I have just bought the 19-piece drill set to. The Bosch Uneo was now already companion of two parades and was there thanks to 2 batteries very good service, also in my garage I had the device in use, and even was able to install a garage door. In the garden and in the amateur field of Bosch Uneo providers also extremely useful. But as soon as you have to drill larger holes the device comes to its limits. I wanted to use a side entrance door and came here not far with the drill, since then had still ran the heavy equipment.
Everything a great device if you use it in particular for the small use in private. One can strains one or another large project are also promising but there are clearly limits. With plenty of power that I would buy again at any time All in all a super perennial device.
