The hammer drill that we want to talk about in this article is professional equipment and is perhaps best suited for small construction teams.
As standard, the retail hammer comes in a case with an additional handle, drilling depth gauge, and a pack of lubricant.
It's about the puncher Makita HR4001C.
This tool has an impressive power for such a handheld power tool: as much as 1100 watts. The puncher is powered by a standard 220 V power supply. The tool has a fairly long cord - 5 meters, although most likely you will need an extension cord anyway.
The perforator is equipped with a standard SDS max chuck, which provides a quick replacement of the drill or crown.
The rotary hammer has three operating modes: chiselling, hammer drilling and standard drilling. That is, it is a full-fledged puncher for both construction and dismantling works of any complexity.
By the way, the tool has only one speed, but it is quite enough.
The Makita HR4001C's RPM and impact numbers are quite low, but the impact power makes up for everything. At a maximum speed of 480 rpm and a number of blows of 2750 beats / minute, the impact energy is 9.5 J. This is enough to split brickwork and even monolithic concrete.
It is possible to install not only drills on the perforator, but also crowns with a diameter of more than 100 mm, which is even suitable for laying sewer and ventilation pipes. Crowns are very useful when laying electrical wiring (when installing socket boxes), laying pipes through walls and partitions, including those made of durable stone materials. Yes, and in the process of carpentry, you may need to make a perfectly round hole in plywood or board.
True, this may require an adapter chuck, since most wood drilling crowns come with shanks and need to be installed in a chuck with sectors and not an SDS max chuck.
As additional advantages of this rotary hammer, it is worth noting the presence of electronic speed control and a carbon brush wear indicator.
Of course, not every person and the construction team can afford to buy this hammer drill, but if you still take it, it will pay back its cost in full.
If we consider the appearance of this perforator, then it differs from the classic scheme of household perforators. The engine in this model is located vertically and the removal of hot air from the engine is downwards. This is very convenient when drilling walls, as dust does not fly into the eyes with the air flow.
