I bought it when I realized that I would have to finish the repair myself. After the impact drill, this hammer drill is just a song. Drilling any hole takes a few seconds (drills are also makita). The power is quite enough to make holes in the bearing walls with a diameter of 10 mm and a depth of about 7-8 cm in 10-15 seconds. It is likely that the professionals have their own preferences, but so far I am very satisfied.
