For those who know how to do at least some of the home construction and repair work on their own, a home tool kit is a must. In our opinion, every self-respecting owner should have a minimum of tools, because even if you hire specialists for repairs or construction, at least sometimes situations arise when you need a hammer or an electric drill for small jobs, but if you do everything yourself, then a set of tools should be big enough.
One of the most important and useful home tools is a hammer drill. If a large amount of work is not planned, a medium or small puncher from a small price category is suitable. With it, you can easily drill a plate of metal or holes for fasteners in the wall. Even if the walls are made of durable concrete, if you drill with a small puncher with a drill with a diameter of 6 mm, then you can do it enough
easy, although you will have to take breaks, because due to the small engine power, the tool will quickly heat up.
One such hammer for home use is KOLNER KRH 520 H.
This hammer drill is powered by a standard 220 V power supply. It has a cable length of only 2.7 meters, so in most cases you will have to use an extension cord or carry it when working.
The motor power of this rotary hammer is relatively small 520 watts. However, this is enough for the maximum speed to reach 850 rpm and the number of strokes of 3900 beats/minute.
By the way, the hammer drill has two modes of operation: conventional drilling and drilling with impact.
Crushing functions in household hammers are very rare, especially in cheap ones. The KOLNER KRH 520 H rotary hammer has a standard SDS+ chuck.
Also, this tool has a number of convenient functions that are very useful when carrying out work. So there is a reverse function that will help if the drill is stuck in the wall. By switching the rotation of the drill in the opposite direction, you can easily pull it out.
The design provides for a safety clutch that will protect the mechanism from breakage in the event of a jamming of the drill.
The drilling depth limiter, unlike most other hammer drills, is made of metal and not plastic.
This perforator has a fairly small weight - 2.7 kg.
On sale you will find the KOLNER KRH rotary hammer in a convenient plastic case. It is very convenient for both carrying and storing the instrument.
The perforator kit also includes: an additional handle, a drilling depth limiter, and carbon brushes.
