Metal, the most commonly used material in construction and industrial production. Not surprisingly, metalworking tools are in demand not only among professionals. High-quality cut-off wheels are capable of cutting metal blanks of almost any size. The main thing is to choose the right consumables according to technical and operational characteristics.
What material are the circles designed for
Manufacturers produce a fairly wide variety of products that can handle not only metals, but also concrete, wood, polymers and even glass. But, cutting wheels for metals have gained the greatest popularity. To cope with the task, manufacturers produce not only universal, but also circles designed for narrower tasks:
- steel, including carbide grades;
- grained gray cast iron
- stainless steel has its own physical properties;
- practically all non-ferrous metals with a viscous structure;
- thin metal coated with a layer of zinc.
Important: the use of a wheel with an abrasive layer designed for a certain type of metal will give a better result. Increased speed, minimum wear. It is especially important to keep the working side intact, without chips or damage.
Features of choosing a cutting disc
In addition to physical dimensions, consumables differ from each other in other ways. As a rule, the manufacturer of the tool, angle grinder, himself indicates some of the parameters that must be observed. But, in general, the choice is made according to the following, the most important criteria:
- Physical dimensions, external and internal diameter.
- The thickness of the abrasive layer depends on the diameter of the wheel.
- The material from which the consumable wheel is made.
- The type of nozzle affects the strength of the attachment to the tool.
- Maximum running speed during rotation.
The last indicator is one of the most important. If it is neglected, one may encounter two problems. The wheel will not effectively process a metal workpiece. Able to collapse right during rotation at too high speeds. If buy a cutting wheel 230 mm, following all the recommendations of the power tool manufacturer, it will last long enough. And it will not be a subject of increased danger during operation.
