Ceiling panels of our home, I had to bring the roof batten construction at the ceiling. My old, green hammer has just five boreholes passed away in seemingly impenetrable concrete. By my probably unbeatable Makita cordless screwdriver I have already decided with a certain expectation for this hammer drill from Makita. Yesterday, the machine has arrived here and today I have my whopping 300 holes drilled into the concrete ceilings. This hammer drill has not even flinch. I believe that if the machine could smile would have probably done the face of this ridiculous requirement for their circumstances. Without much effort on my part, the machine pulls almost autonomously in the concrete. Good drill but you should be definitely buy it. One does not spans indeed an ass in front of his Ferrari. Ürigens while I screwed the battens, my wife cable slots "braced" with the Makita and they even had fun doing it. Unconditional purchase recommendation !!!
