I had already a fairly powerful puncher but heavy and I wanted a lighter and compact drill for drilling and chiselling work. I saw that my mason was already equipped with this type of puncher who gave him any satisfaction. I decided to buy the same and I'm not disappointed by this product. The pros: very light for a puncher and very compact, very well to drill close to a wall or pillar, it sneaks everywhere. The -: not drill into the power cabinet and a fair bit but then it would get in the Bosch range and it is not the same price.
