A hammer drill is an electric drill with an impact mechanism. It uses the principle of shock formation such as electro-pneumatic or electromagnetic.
dewalt rotary hammers have proven themselves well in the modern power tool market. Such a construction tool is primarily designed for destructive work, usually with hard materials. Among them are brick, concrete, artificial and natural stone. The functions of a hammer drill are very similar to an electric drill. In this regard, some consumers experience difficulties because they do not understand the difference between these tools. But they are very different from each other.
Want to buy a puncher? Let's first of all understand the structure of the punch and, in principle, its operation.
The working bodies of the punch are a chisel, lance, drill or crown. Due to the specific nuances of the principle of operation of this device, the drills used differ from the usual spiral ones used in the usual drills. The main difference is the slightly modified tail section.
The special fit of the part for cutting is dictated by the need to move the drill in the direction of its own axis throughout the entire time of operation in the impact mode. But ordinary drills can also be used when working with a hammer drill. To install them, you will need replacement cartridges or adapters. Cartridges are much more convenient, and they are most often used. Interchangeable adapters represent a three-jaw chuck that fits on the main chuck of the hammer drill, making the design significantly longer. This causes increased play, as well as radial runout, and more noticeable displacement of the drill from the desired position. Please note that it will not be possible to completely get rid of the radial displacement of the drill in the chuck. This is due to the design of the rock drill. That is why, without using additional adapters and nozzles, you will not be able to "jewelry" work with a small diameter drill. To perform precise manipulations, completely different tools are needed.
