Nowadays, few people can see a hand drill. And earlier, about 20 years ago, it was necessary to stubbornly turn the handle and press it with your shoulder into the drill in order to get a hole. Now, it is much more convenient to do it. Now I make both drills and screwdrivers. Using interchangeable attachments, the drill very easily turns into a screwdriver, mixer, grinder. An impact drill can hammer and drill in poor quality concrete or bricks. For high quality concrete, a rotary hammer is recommended. The power of modern impact drills ranges from 460 W to 1100 W. Reverse and rotation speed control is a required attribute. In the repair, you will also need sand with delivery, you can buy it on the website .
Drill drivers are usually used to screw in self-tapping screws and screws. This greatly facilitates the time-consuming and time-consuming process that takes an integral place in every production. The speed regulator is of great importance for the tool. There are from 6 to 22 positions in various modifications. If you set the drill to a low position, you can very accurately control the process and not miss the markings. Also, the rotation of the drill is used to mix paints and glue. For this, there is even an additional attachment specially available. And using a grinding attachment, you can smooth the surface of the material that you are processing.
