How to choose a puncher?

The puncher is one of the most purchased types of power tools, designed to destroy all kinds of hard objects, for example, stone, concrete, brick. Since the popularity of this tool is quite high, the market offers a variety of options, so buyers have a question: how to choose a punch? Let's deal with this issue.

How to choose a punch: some important points

The main distinguishing feature of this tool from a shock drill is considered to be the duration and trouble-free operation in the process of crushing of solid materials. In this connection, it is first necessary to determine the goals of using a perforator. In the event that you need it exclusively for drilling, then you can purchase a single-mode tool, which is not only cheaper, but also easier. If you need a drilling mode with impact, you can buy a dual-mode tool, with which you can not only drill concrete, wood, steel parts, but also beat off the tile, clean the stone walls. The professional punchers have three modes, which allows you to make openings in the walls and concrete floors, engage in grooving work, peg in the ground rods. But its weight is more than six kilograms.

How to choose a punch: we evaluate technical characteristics

When choosing a puncher, its technical features play an important role. It is important to note that the power of this tool has a direct effect on the speed of its drilling: the higher the speed, the more power the tool has. However, it is necessary to take into account a very important fact: a powerful puncher is usually equipped with a larger drill, which makes it much harder. Often there are instruments whose weight is more than ten kilograms. That's why you need to be prepared for significant energy costs while working with him, and also that he will take away a lot of energy from you. With increasing power, the frequency of impacts and their energy increase. When deciding which punch is best, it is worth paying attention to the technical documentation, in which all relevant information is necessarily indicated.

How to choose a punch: functions

It is important that the device has the ability to turn off / on the impact function, in which case it can be used as a drill. Such a puncher function is secondary, but it can be very useful if you do not have a drill handy. It is important not to forget about checking the presence of the adapter cartridge, with which you can install drill bits for the drill. It must move very easily, the fastening of the drill should not be rigid, which will exclude any slip in a strong impact. Almost all rotary hammers have a speed regulator, however, not all are equipped with a maximum speed limiter that allows you to work without disturbances with a trigger that is compressed to the stop. At the same time, the cost of the perforator is significantly increased, but safety is much more important.

The switch of the direction of rotation is also an excellent addition to the limiter, it allows to quickly and losslessly free the drill when jammed. This makes it possible to use a perforator and as a screwdriver. If we talk about how to choose a puncher for the house, then it should be noted that the best models are those equipped with planetary gearboxes with two speeds.

A quality tool must have an insulated casing made of a solid metal sheet. Such materials have excellent heat transfer, allowing to cool the tool effectively. The presence of special inserts between the housing parts allows to reduce the vibration level by 70%, and this is very important for long work. At the moment, the most popular brands among consumers are Makita, Temp and Bosh.

These are common nuances that you should know about before you go for a puncher.
