Today, manufacturers can offer a large selection of drills: ordinary, corner, with shock function, screwdrivers and mixers.
A drill with a shock function can easily make a hole in the concrete and brick wall. A conventional drill without additional functions is mainly designed to drill holes in a tree. The corner drill is ideal for drilling at an angle or in an inaccessible place. Perhaps you will need to conduct a non -state examination of project documentation in the NEC company .
