Perforators are widely used in construction work, both by professionals and apartment owners themselves. Often people do not distinguish the punch from the usual hammer drill, so the question of choosing a tool becomes quite vague. Before choosing a punch, you need to understand a few basic points. One of them is the difference between a perforator and a drill. The second is the specifics of the work and the classification of the instrument. In the article we will tell you how to choose a good punch for work.
Types Punchers have their own classification, therefore, it is necessary to understand it.
Classification by weight:
Thus, depending on the included functions, the widest range of works is available to perforators:
As already mentioned, many people simply do not see the difference between a percussion drill and a perforator, and this sometimes cause of fatal errors. The difference lies in the principle of action of the tools. In a conventional drill, the effect produced depends strongly on the force of pressure of the master on the tool. It is not necessary to press on the puncher, it can lead to breakage. The perforator contains an integrated pneumatic or electromagnetic mechanism, which produces an impact force.
Working with a punch requires a force that is three times less than when using a hammer drill.
In order to choose the right punch, you need to know its difference from the drill and use it for its intended purpose.
Operation When working with a perforator, you must follow certain rules.
Both the drill and the punch can function as each other. However, working with a hammer drill, as with a drill, is inconvenient. At the same time, the drill, carrying out the work of the punch, wears out. Therefore, the choice depends on the material with which to work.
If you have to work with all the listed materials equally often, then it is better to have both tools. This will greatly facilitate the process and keep the units in good condition.
You need to choose a punch based on the complexity and nature works In this case, do not forget about the components to the tool. So, you need to take a set of drills in advance. Often when buying a unit, you can find that the basic set of drills is already in the package. This is quite enough for the work of an average complexity at home. However, for more complex work, especially if we are talking about a professional tool, you will have to select components individually.
Drills are more expensive than drills. This is due to the fact that they are subject to increased requirements.
In order for the punch to work as a drill, you need to purchase a special adapter. When buying, you need to ask if it is included. Sometimes manufacturers include such parts in the kit.
Spare brushes must be purchased if the work is done daily. This is very important for craftsmen who use the tool for a long time.
One extra set of brushes will do for homework. Often they are already in the package. Before you choose a punch for the house, you need to see if there are brushes in the kit. This will save.
Specifications The punch has a number of characteristics that are very significant when choosing a tool.
Advantages Often, many beginners are surprised: why do we need a punch if you can buy a drill for work? It is cheaper, components for it also cost an order of magnitude less, and it is also compact and familiar. However, not all so simple. There are some subtleties that you need to know before choosing.
The puncher is really quite an expensive device. It belongs to the profinstrument. But its cost justifies itself. First of all, it is worth mentioning the quality and durability of a good perforator. Another undoubted plus is the speed of drilling.
The drill will not be able to provide such high speed performance, because its hammering function is just an addition to the main drilling one.
The hammer drill works excellently on concrete, plaster and soft materials. A special cartridge ensures reliable operation of the device, while no effort is required from the master. If you need to make a quality repair, then there can not do without a punch. Of course, ideally, the master should have a puncher and a drill.
