Purpose and functions
The instrument received its name from the Latin word "perforo", which translates as "punch".The principle of the perforator consists in strong and rapid impacts, which are applied to the surface being treated. The device is used for making holes in concrete, reinforced concrete and brick during construction or repair work.
In addition, some models can be used as a simple drill for various materials or as a small jackhammer for cutting niches, chipping tiles, channeling walls in a wall and so on. In terms of functionality, they are one-, two-, and three-mode. The single-mode device performs only one function - it provides rotation and impact.
Dual-mode punchers combine the first function and the ability to do rotation without impact or impact without rotation. The three-mode tool is the most functional and has the functions of rotation without impact, with impact and chiselling. Determining which is the best perforator from these three types, you should focus on the scope of its application. After all, the best tool is the one that is most suitable for the required work.
Tip! If the financial opportunity allows, it is better to choose the most functional tool, because it can be used for a wider range of work.
Technical data
The main technical data of the puncher includes the following characteristics: engine power, drilling diameter, weight, impact frequency, impact energy.
The power of the perforator motor ranges from 250 to 1500 watts. The most popular are tools with a power of 500-800 watts. This capacity is quite enough for a variety of works in everyday life. The impact energy is one of the most important indicators of the apparatus. On the strength of impact depends on what strength it will be possible to destroy the material. Another important indicator is the drilling diameter. It depends on the nozzle. The crown allows you to make holes three times more than using a drill.
Note! The diameter of the drilling depends largely on the type of punch.
The speed of rotation of the cartridge for all tools is approximately the same and does not exceed 1000 rpm. The lighter the device, the faster the rotation speed. So, light perforators can reach speeds of 1000 rpm. Heavy ones have a speed of about 100-200 rpm. The frequency of impacts also depends on the class of the perforator. Another characteristic is the weight of the instrument, which directly affects the operator's ability to work for a long time. Weight is from 2 to 12 kilograms.
Which perforator is better - we determine by weight
The classification of perforators is determined by the type of drive, mass and power, purpose and type of cartridge. By type of drive they are divided into electrical, pneumatic and petrol. The best of them is considered an electric tool, so it is the most common. The batteries are very mobile and do not tie the operator to a specific place. However, pneumatic perforators are used at sites with increased fire danger.
On purpose, the perforators are divided into amateur( household) and professional. To household tools are light models, and medium and heavy are considered already a professional tool. Now consider what kind of perforators are, depending on the weight:
- Lungs are instruments weighing up to 4 kilograms and power of 400-700 watts. About 80% of the devices belong to this class;
- Middle class - their weight is in the range of 5 to 8 kilograms. The power already reaches 1200 Watts, which makes it in demand among professional workers;
- Heavy class - the weight of such punchers starts from 8 kilograms, and power - within 1500 watts. This unit is used exclusively for professional work.
Note! The best perforators are the middle class, as they are capable of both performing professional tasks and being used in domestic repairs.
