Watt Angle Grinder Adjustable Speed

When working with metals, even in small workshops, a reliable power tool is required. Choosing an angle grinder with a soft start is not difficult, given that there are many models from different manufacturers on the market. There are general principles that should be followed when searching for a suitable device.

Features of the device. Differences between models

angle grinder (angle grinder) appeared in the middle of the XX century and quickly became an important tool for manual processing of metals. Its advantages:

  • Versatility: the tool allows you to cut, strip and polish.
  • Increased processing speed compared to hand tools and machine tools. this applies to small amounts of work.
  • Ease of maintenance. no need to set up an angle grinder, and its maintenance consists in periodic cleaning, dust blowing.
  • The small size allows you to transfer the angle grinder to the working room.

But there are also negative points:

  • Large parts and structures are difficult to handle.
  • A 220 Volt network is required. However, a cordless angle grinder is available.
  • Failure to observe safety precautions can result in personal injury.

The angle grinder is an electric motor that transmits torque through the gearbox to the main shaft with locking nuts. Circles are clamped in them: cutting, cleaning, polishing.

It is recommended to purchase models with a soft start. this option increases the life of the motor. After pressing the button, the engine does not immediately reach its operating speed, but with a slight delay. that is, it is spinning smoothly.

Adjusting the speed of the electric motor expands the scope of application of the angle grinder. the tool can be used for grinding and polishing surfaces. These operations are carried out at reduced speed.

Choosing a soft start angle grinder: highlights

Before buying a power tool, it is recommended to clearly determine what amount of work will be performed with its help:

  • Daily use for several hours a day.
  • Periodic work: several times a week for 2-3 hours.
  • The tool is needed for home use. as needed.

In the first case, you should pay attention to the models for professional use: these are powerful (more than 2-2.5 kW) and ergonomic angle grinders with soft start, speed control. But the cost of such grinders will be high.

For periodic operation, it is enough to purchase a machine of medium power. about 2 kW. If the work will be performed with thin or soft metals and alloys, then 1.5 kW will be enough.

For use at home, in the garage or in the country, it is better to get a small angle grinder 900-1000 watts. This is enough for most work: car repair or the creation of small metal structures.

Before buying a power tool, it is recommended that you pay attention to important things.

  • Cord Length. Power cables that are too short will make the job uncomfortable. Even if you have a portable extension cord at hand.
  • Handle. for long-term work it is better to choose an angle grinder with a vibration-absorbing handle. This will reduce fatigue during work.
  • Type of model (for right-handed or left-handed people). a number of manufacturers produce an angle grinder that can be convenient just for left-handers. with a non-standard position of the handles.
  • Attachment of protection. the casing is fastened either with bolts to the case or on latches, which allows you to quickly change its position. A hard mount will force you to unscrew and tighten the screws each time.
  • Type of brushes. carbon elements can pass through the case, then they are changed without removing the plastic parts from the angle grinder in 2 minutes. If the brushes are inside the angle grinder, you have to disassemble the tool.
  • Clamping nut. there are ordinary ones, which are wrapped with a pin wrench, and there are quick-clamping nuts. they are twisted by hand.

You should also pay attention to whether there is a service center of the manufacturer near the place of residence. This is important if you are buying a professional tool, it may eventually require replacement parts.

Possible term of occurrence

On a power tool for professional use. 18-20 months.

On expensive models: 24-30 months.

On professional models. after 2-2.5 years.

With proper maintenance and careful handling, the angle grinder will last much longer. The table shows the statistics of the service workshops.

How to service an angle grinder

The rules will maximize the life of the angle grinder.

Before operation, you need:

  1. Inspect tool: for damage to cable and housing. Bare wires will cause electric shocks or short circuits in the network. Due to cracks in the case, the angle grinder may fail during operation. Often defects can be eliminated with the help of repair adhesives, “cold welding”.
  2. Before connecting to the network, you must install the drive. After that, scroll it by hand, making sure that it is installed correctly. Installation must be carried out using special keys that are supplied with an angle grinder. Do not tighten the nut strongly. It is recommended to place cardboard gaskets between the disk and the clamping nut. they facilitate removal after work.
  3. Connect the angle grinder plug to the network and try to start it. It is important to ensure that no extraneous noise is heard, and sparks do not pour in their vents.

During operation, it is strongly not recommended to lay the working tool on a workbench or floor. This can cause both injuries and breakdowns of the angle grinder. If the geometry of the circle is badly broken, it is better to replace it. Increased vibration adversely affects the condition of the gearbox parts.

After work you need:

  1. Disconnect the tool from the network.
  2. Carefully remove the circle using the company key.
  3. Blow out vents for dust and chips with compressed air. At home, you can use a vacuum cleaner.

It is recommended that approximately every six months (with intensive use. once a month), disassemble the housing and thoroughly blow through the internal elements. A brush is also used to remove dust.

The angle grinder with soft start and speed control is an indispensable tool for repair, production and construction. Choosing a quality tool has become not so difficult. high competition allows you to purchase a relatively inexpensive and reliable angle grinder.

The main thing to pay attention to:

  • The period for which the manufacturer guarantees the reliability of the angle grinder.

It is important to carefully operate the purchased power tool and to service it in a timely manner.
