A hammer drill is a tool that can be useful in everyday life at any time. Professional rotary hammers copes with drilling holes in a brick, concrete and any other surface by rotational and reciprocating movements. It is due to them that the high efficiency of the device is ensured.
Secrets of choice
For professional purposes, electric rotary hammers are best suited to withstand heavy loads compared to impact drills. At the same time, the well-thought-out design allows you to use professional punchers both as a drill, and as a device for drilling with a shock effect, and as a chipper, if you need to make strobes for wiring or when chipping tiles. So when choosing a professional device, it is still worth starting from their main technical characteristics:
- Forces of impact on the material. This characteristic for the punch is the main, as it depends on where the device can be used. The power of the motors directly affects the strength of the impact. Suppose a power of 3.2 J is enough to process a brick surface, and if work with reinforced concrete or stone is required, more powerful models will be required.
- Tool rotation speed: it affects the frequency of impact. Making holes of large diameter requires a lot of energy, and it can be developed only if the rotation speed is reduced.
- Features of work: professional punchers can work from the accumulator or from a network. It is noteworthy that both options differ in performance. But the battery models are autonomous, so they are the best suited for work where there is no network.
- Presence of operating modes: some punchers can work in several modes - they drill, drill with percussive effect and perform percussion work.
- Engine layouts: it can be located horizontally or vertically, and the first options are more common. The vertical arrangement makes the device itself compact and its design more balanced. The feature of these tools is the ability to withstand severe loads, easy cooling and less vibration that goes to the handle.
For some, certain additional features may be important, for example, protection against overloads or the possibility of electronic speed control. All this should be considered when choosing one or another model. Now we offer an overview of popular brands and models of rotary hammers, of which there are most good reviews.
