Tips for choosing cutters and scissors ↑
The tool is operated for as long as possible, while purchasing scissors you should look at several parameters:
- Blade. It should be made of stainless steel. Thus it is necessary to pay attention to the sharpening angle. To effectively cut it needs to be about 30 degrees.
- Arm. To work with the tool not to experience constant fatigue and discomfort, you should carefully examine the handle of the selected pair and try them in your hand. Best of all are the hand device with rubber handles.
- Support for the pipe. This element needs to be broad, so that the cutting took place under a right angle. If the pipe is not properly based on the scissors, they are not worth buying.
- Automatic reverse abstraction. If the scissors after compression remain closed, they will be uncomfortable when you need to make the cut in several sections of the pipe. So you need to look for a tool with automatic retraction to starting position.
- Clip. Meet a scissors without locking quite difficult, but the choice still should pay attention to it, as there are models without it.
If you have to cut pipes of small diameter (43 mm), to buy large and powerful tools makes no sense. But if they are operated constantly, the cheap purchase is not worth it.
How to use ↑
Operated shears for plastic pipes quite easily. For cutting of the pipe just need to click several times on the arm. After each push, the blade is lowered to a certain depth, remaining in this position. Below the cut was smooth, you should make every movement smoothly. If cutting with quick movements, the edges may be uneven or the whole slice is «beveled».
Also, the unevenness may appear due to the insufficient length of the blade. It should be longer than the diameter of the pipe. Otherwise, make the perfect cut will be difficult. If you cut off the tube carelessly, after sealing fittings it may begin to leak.
