It drills in speed, like cheap perforators from Interskol, compared visually right before writing this comment, with a drill of 6 in 500 concrete, this boshik was very pleasantly surprised, I took it with a blow, since the Interskol has a short wire and thought a la it would come in handy, but As a result, he gives a light to this interskol, the only thing that the gearbox is heating up, drilled 30 holes with a diameter of 6mm and a depth of 50mm and it was no longer comfortable to hold, let it cool and again into battle (it is the gearbox that heats up, the motor is about 45 degrees)
