Perforator as a type of construction tool
In the process of carrying out construction work, drilling is very often necessary. In such cases, it is necessary to use a perforator, since it is almost impossible to perform such an operation with other tools..
Currently, there is a very wide range of this kind of products on the market for construction tools, therefore, in order to choose the tool that is most suitable for solving certain tasks, you should take into account some of the features of rotary hammers..
Before you buy a hammer drill, you need to take into account that such a tool is divided into three classes: heavy, medium and light. The lungs include perforators, the mass of which does not exceed 3 kilograms, average — up to 5 kilograms. Heavy rock drills are commonly referred to as jackhammers and weigh more than 5 kilograms.
The lightweight rock drills are designed for drilling small diameter holes in concrete. The middle class tool can be freely used to work with reinforced structures. Heavy-duty rock drills are typically used as a simplified version of a conventional jackhammer..
In those cases when a blow without rotation is necessary, the mass of the perforator does not play a big role. At the same time, for drilling, for example, reinforced concrete with a «mesh», you will need a hammer drill of at least a middle class.
As you can see, rock drills are designed to work with hard materials. The most «dangerous» materials are considered to be concrete and brick. Concrete dust that gets into the hammer drill during operation can completely disable the tool..
Therefore, in order to avoid unpleasant situations, one should not neglect the lubrication of the hammer drill, especially since such a procedure is quite simple. Repairing such a tool, in the event of its failure, can be very expensive, since it must be done in a specialized service center..
In the process of using the tool, you should periodically pause during work. This will prevent overheating of the instrument. Also, to increase the service life of the hammer drill, it should be noted that the plastic housing removes heat much slower than metal, therefore, at low speeds, the tool heats up no less than at high speeds..
