FAQs

Can angle grinders be used for cutting wood?

Yes, it can be used, but it’s not advisable. It’s better to use tools specifically designed to cut wood.

How to consider RPM for grinder and disc?

Always make sure the rpm of the disc or wheel is more than the rpm of the angle grinder. We cannot use a cutting wheel that is designed for 10000 rpm on a grinder with rpm 12000.
Always follow and consider manufacturer rmp values.

What operations can be performed using an angle grinder?

Cutting, cleaning, buffing, sanding, grinding, and in some cases carving can also be done.

What is angle grinder kickback?

Angle grinder kickback is when the disc got stuck or jams in the workpiece. It happens when the disc type or speed is not correct for the workpiece you are working on. Try to adjust the speed and type of disc and we can overcome this issue.

Can angle grinders be used for cutting stainless steel?

Yes, it can be used for cutting stainless steel and grinding SS. Make sure to use a disc specially designed for ss. While grinding high surface finished SS black marks will appear on it due to heat which then had to be removed using SS cleaner or fine sandpaper

What to look for before buying an angle grinder?

It depends on your usage and the type of workpiece you want to work on but the common features to look for in any grinder are below

  • Wattage
  • Speed (RPM)
  • Brush or Brushless
  • Power source (110 or 220)
  • Safety Feature
  • Shape and ergonomics

Things to Remember

Always choose a disk of Higher rpm than the grinder
Always use the angle grinder with a handle and safety guard.
always wear complete PPE while operating an angle grinder
It’s highly recommended to use a grinder with a dead man switch (also depends upon usage)
If you feel the motor is getting extremely hot then stop the activity and let it cool.
don’t push too hard while cutting or grinding.

Conclusion:

it depends upon our usage and type of work to choose a perfect grinder for us. If you want a grinder for general DIY home use then even a small power low rpm grinder will help with less cost but if you want to buy a grinder for heavy work for example you want to buy a grinder for a steel fabrication workshop then its better if we go for heavy-duty high rpm and power grinders with considerable warranty and affordable price range. It is advisable to go after brushless grinders for heavy work as they have a long life before breakdown.
