The set is highly recommended. Although I have only 20 square meters of natural stone and then the thick-bed mortar and pried a little lime sandstone broken masonry, of wear but still nothing to see. All work with the wide flat chisel, although that is specifically not intended for demolition. Impact energy of my machine is equipped with 3.2 Joule not just at the bottom of the rotary hammers. The chisel may not be professional quality, performs for the ambitious handyman of only occasional chiselling, but perfectly adequate. It should be noted only that the broad flat chisel is not curved. This is not as clearly seen in the picture.
