For independent installation of systems, the presence of a pipe cutter is the main condition. It helps to quickly and accurately cut pipes of a given length. The cuts are smooth and neat, which greatly facilitates the work of plumbers and installers.

To cut such elements, you can use a hacksaw for metal. But the result is of poor quality: there is no cutting accuracy, there are numerous burrs on the end. You have to additionally align the edges, using specialized tools for this purpose. In addition, a hacksaw cannot always be used, as there is a special material that is not suitable for these procedures. Precise 90-degree cuts are achieved by using only a pipe cutter.
When carrying out perpendicular cutting with equipment, the ends of the workpieces are smooth and of high quality. Its performance indicator far exceeds the capabilities of a hacksaw. Devices are widely used in the construction of new facilities, the dismantling of obsolete heating and water supply systems, and the replacement of damaged areas. With their function, they cope "excellently".
It is considered the best tool when working in close proximity to explosive objects or where there is no possibility of connecting to the electrical network.
A review of designs shows that they all have design differences, but they have two principles of operation:
View | Description |
---|---|
Orbital | The movement of the cutting part occurs in a circle. The fixed part wraps around the tool and rotates. Requires a large free space for the operation of the device.The furrow gradually deepens until the end of the cut. Used for cutting special material in installed pipeline. |
Stationary | It is supposed to have a special machine. The device is stationary, and only the part rotates. Copes with significant product diameters. The method is used in the production of a large volume of material. |
The devices differ in the following parameters:
For industrial purposes, devices with a non-mechanical principle of operation are used:
The body of the equipment is made of the following materials:
In order to resist corrosion, individual elements of the body can be coated with a protective layer based on chromium or a special coloring composition (powder). The steel structure is assembled from individual elements, which are also subjected to a procedure such as hardening.This provides significant stability of loaded and rubbing against each other nodes. Chrome-plated components are not afraid of moisture, have a good wear resistance, are resistant to corrosion, and have an excellent appearance. Cutting elements can be steel, tool or made from a special steel grade (alloyed).
The weight and size of the selected device depend on where the tool will be used and what maximum diameter of the elements will have to be cut. Scissors for 42 mm products have an average weight of 300 to 500 grams, their length is from 250 to 350 mm. As for electrical devices, their mass and dimensions depend on the engine and the mechanisms for fixing product fragments.
After reviewing the data given in the product passport, the buyer can identify information regarding the minimum and maximum diameter of structures that the selected unit is able to handle. The pre-installed ratchet mechanism will help to cope with thin copper walls, however, the diameter of the working raw material should not exceed 42 mm. Electric and pneumatic models work with a diameter of up to 1500 mm, roller - 50 - 100 mm, cutting - up to 100 mm.
The best manufacturers produce popular models of the following types:
Tools differ in the principle of operation, and therefore they are divided into the following types:
Everyone has their own criteria for choosing a pipe cutting device. Which one is better to buy depends on many factors. If you review the rating of quality products, you may be surprised at the variety of equipment for copper, aluminum, steel and other types of pipes. What matters is how much the item costs. But, according to buyers, this criterion is not fundamental.
The recommendations of experts boil down to the following: if you carry out professional activities using metal-plastic pipes, then you should buy a pipe cutter - scissors with a ratchet mechanism. Roller models do an excellent job with metal products.
The advice of professionals is as follows: you should not save on such a tool. Budget options cannot be characterized by high service life and quality. What should you pay attention to in order to avoid mistakes when choosing? First of all, special attention should be paid to the raw materials from which the product case is made, as well as to the basic set of device functions. It is advisable to choose a steel case. It is more practical, has high wear resistance. Which firm is better depends on the preferences of the buyer.

The work of a pipe cutter is associated with one important point - to choose the right clamping force for the pipe. Excessive force can lead to the formation of a helix, which is almost impossible to correct. You will have to choose another place for cutting. Rapid rotation of the tool can cause the pipe walls to close.
Masters recommend to properly care for the device:
