I decided to buy myself a tool for completing repairs in the apartment (hang chandeliers, mirrors, lamps, TV brackets) + help my father in the country (construction is in full swing). I immediately took a set of Makita drills (China) and a German drill for 10, they all fit into concrete equally well. In half a day I hung 2 lamps (drill for 6), 1 chandelier (drill for 6), 2 mirrors (drill for 8), moved the switch (crown for 68), cornice (drill for 6) and TV bracket (drill for 10), more time was spent on measurements and leveling. Drilling speed approximately one 40 sec. for 6 holes with a depth of 7 cm with a drill for 10 (panel house). I recommend it, it lies well in the hand, minimal vibration, the neighbors do not hang themselves, it does not stink at work, it does not heat up, it does not spit oil. It remains to check the electronic reverse in operation.
