Punch - what is it?
The modern perforator is an electric tool characterized by impact-rotational action and is designed to create holes in solid materials( concrete, bricks, etc.).In some cases it can be used as a jackhammer. That's why the puncher is one of the most popular tools on the construction market. Drilling, shtroblenie holes in the walls, tile breaking - effectively and in a short time to perform this work will help it.
Inexperienced people often confuse a household puncher and impact drill. In order to avoid errors during the purchase, it is recommended that you first learn the fundamental differences between these tools. Firstly, when a perforator is in operation, the impact force is created by pneumatics or electromechanics, and when working with a drill, it is created by means of a mechanical transmission. Obviously, in the first case, the drilling force will be greater than in the second, respectively, the perforator is more efficient in operation.
Secondly, these tools differ in the design of the drill. The drill chuck does not always guarantee protection from turning the drill and does not increase the impact force at the drilling site too much. A certain "hybrid" of these two tools can be considered a drill with a perforator, which is also quite widely available on sale. So, what to look for in order to choose the best puncher for the house?
How to choose a puncher - we study the characteristics of
If you are not too experienced in acquiring construction tools, and the question of how to choose a punch is quite acute, then it is necessary to pay attention to the following performance characteristics of the product:
- Power.
- Rotational speed of the drill.
- Energy of impact.
- Drilling diameter.
The speed and quality of drilling the required holes directly depend on the power of the product. If your plans include working with excessively hard materials, in which you need to make large holes, then give preference to a more powerful tool. It should be remembered that the higher the power of a puncher, the heavier and more massive, accordingly, it will be more difficult to work with it. As for the rotational speed of the drill, the larger it is, the more convenient it is to use a perforator.
Today, products are on sale, the rotational speed of which is, as a rule, 600-1500 rpm. With a large bore diameter, the rotational speed must be quite high to ensure efficient operation.
When you decide which puncher to choose for your home, pay attention to its impact energy. Its indicator is one of the most important, since it directly demonstrates the capabilities of the instrument. The impact energy determines the maximum drilling diameter of the hole and the efficiency of the material breakage. In some models of perforators, the impact energy can reach 15 J. With regard to the drilling diameter, as the working parameter of a household perforator, then most often the maximum value is indicated by the manufacturers in the instructions to the tool.
Selecting a puncher for a house - choose the degree of functionality of the
Before choosing a puncher for a house, you need to focus on the degree of its functionality. Do not be attracted by too many functions of the tool, they may not be needed at all. You must have a clear idea of the purposes for which it is acquired. So, many models of punchers have a built-in drill hole depth meter. It allows you to determine exactly whether the drill reached the desired depth.
Each perforator can work in this or that mode, for which it is equipped with a special switch. It allows you to select the operating mode of the product, thereby controlling the drilling speed and efficiency. Thus, when drilling a large hole, it is recommended to switch to the slow rotation mode of the drill.
If you need to make a small hole, the speed can be increased by switching to another mode. Convenient and the function of reverse rotation, which allows you to easily pull out a drill, stuck in the material. After that you will be able to resume your work.
