4. What are the advantages of a variable speed angle grinder?
The main advantage of a variable speed angle grinder, particularly for wood applications, is the ability to slow down the wheel or blade.

6. What are the disadvantages of an angle grinder?
Angle grinders can be potentially dangerous power tools. They can cause severe cuts due to kickbacks. There is also a risk of discs shattering or disintegrating, which can produce fragments that may cause injury, especially to the eyes or other parts of the body. Proper safety precautions and protective gear, such as goggles and gloves, should always be used when operating an angle grinder.
7. What is the best RPM for a grinder?
The ideal RPM for a grinder depends on various factors, and there is no one-size-fits-all answer. However, in general, if the RPM is less than 300, there will be no production and fineness.
