angle grinder (angle grinder) with speed control


Maximum RPM reflects the idle speed of the spindle per minute. Models with higher maximum rpm provide high performance, even with less power. Depending on the model of the angle grinder, the maximum number of revolutions can be from 6,000 to 15,000 rpm. over, for “Bulgarians” of a larger size, with a disc diameter of 230 mm, this figure is lower, and for models with a disc of 115 mm, 125 mm, respectively, higher.

The tool weight parameter when selected determines how much force the user will have to apply to move the device. Ultimately, this means how tired the worker will be when using the grinder.

Weight depends on the dimensions and power of the electric motor of the equipment. the higher the power, the higher the dimensions and weight.

Heavy grinders are more stable when processing flat surfaces, but they are not convenient to use if you need to spend a lot of time with the device “on the fly”.

Low weight determines not only ease of control, but also maneuverability, smoothness, natural holding by the user.

Adjusting the speed of the grinder allows you to optimally adjust it for grinding materials of different density. This is a necessary function for those who have to work not only with wood, but also with plastic and metal surfaces.

Soft start, or a starting current limiting system, allows you to limit the starting current to 16 A. This is necessary in order to connect the grinder to a household power supply without damaging it.

Concrete dust. corrosive abrasive environment for any power tool, therefore an angle grinder is used for cutting, chasing or grinding building materials only if they are equipped with an electric motor with windings in a protected design.

An electronic constant speed control system protects the angle grinder motor from overloading and related breakdowns. The system keeps the speed constant, regardless of the change in load level.

Using an optional vibrating pen helps to reduce vibration when using the tool. The built-in damper dampens vibration vibrations, which makes it much easier to work with the tool, reduces fatigue and, ultimately, protects the user’s health.

A number of angle grinder models presented on our website are equipped with an unintentional start-up protection system. In the course of working with an angle grinder, situations may arise when the tool remains connected to the mains without the knowledge of the operator: emergency shutdown and subsequent sudden turn on of electricity, violation of safety precautions. Such situations are dangerous if the tool is turned on unintentionally, which could result in operator injury and property damage. Anti-unintentional start-up function prevents accidental start-up of the grinder and related problems.

  • Angle grinder power. The power depends on how the angle grinder handles the loads. For long and continuous work, give preference to more powerful devices. Thus, they will not break in the process. But for household tasks, devices with an average power, low-power angle grinders are also suitable. In addition, high-power angle grinders are designed more for professional activities and their cost is much higher.
  • Diameter of the working cutting disc. This indicator will determine the depth of the hole and cut that will be created by the device.
  • Rotation speed of the device. Affects the performance, as well as the speed of the task.
