Puncher is a construction tool, the main purpose of which is punching holes. This gives rise to some confusion. Often it happens that the impact drill is called a "perforator". By definition, in principle, everything is correct, but in fact it turns out that there is a difference. In operation, the drill mainly relies on rotation. The puncher, on the contrary, punches his way through blows. Rotation only takes away the waste material and helps it in forming the holes. The BOSCH Hammer PRT800c Premium perforator consists of a cylinder, piston, striker and so-called "drunk bearing", which converts the circular motions of the engine into reciprocating. Our heroes today are outstanding representatives of their class from a well-known manufacturer of construction equipment.
The first is the Hammer PRT800c Premium perforator for those who like the classics. Small (weight not more than two kilograms), but with a blow power of three Joules. This is the optimal ratio for such a modification. A well-thought-out design, an elastomeric lining and an impact-resistant casing make working with it pleasant and comfortable.
PRT800c Hammer - multi-mode puncher. The switch on the left side of the case translates it into any of the three main operating modes: shock, drilling (this is a blow with drilling) and drilling. There is also a function of unstressed rotation. Electronic speed adjustment and reverse enable to use it as a drill and screwdriver.
PRT800c Hammer - the perforator is durable. The dust protection system significantly increases the working life of the tool. The windings of the engine are much more reliable than conventional ones, because they are double insulated, which means that the tool can work under the most difficult conditions. With such an unpleasant incident as jamming, you will be protected by a safety clutch. The impressive length of the cable allows you to work at a decent distance from the power source.
Another noteworthy tool is the PRT650A Hammer - a lightweight puncher with an engine power of 650 watts. The speed of rotation is up to 100 rpm, the developed impact force is 2.2 Joules. The tool is designed for drilling holes in stone, brick, plaster, concrete and similar materials. Located on the left side of the case, the switch switches the punch between modes of operation. There are only three of them: drilling, drilling and impact. The "Drilling" mode allows you to make a hole of different diameters - from four millimeters and higher. In doing so, you can use drills, peaks, chisels. All these attachments can be used in the "Beat" mode. It is designed to work with tiles, concrete, brick and plaster. In general, PRT650A Hammer - universal puncher. He can drill wood, metal, plastic and similar materials. The instrument is also equipped with double insulation, which ensures the reliability of electrical protection. The cartridge is dustproof, due to which the life of your puncher is very large. Well, and to the non-functional advantages of the instrument can be attributed a convenient plastic case for transportation and storage of tools and a long cord, which gives an excellent freedom of action.
