Some things you can do with an angle grinder are grind, cut meta, polish metal, sand metal etc.
Angle grinders are very versatile tools and can be used to grind metal and cut tile, stucco and pavers, rout out mortar and also they can sand, polish and sharpen things as well.
A grinder and an angle grinder are similar but an angle grinder is a handheld grinder that is shaped with the head of the tool at a 90 degree angle from the shaft.
A die grinder is a straight grinder and a grinder can also be a bench grinder that you grind metal or sharpen blades, tools etc.
An angle grinder is called an angle grinder because of the way the tool is shaped and because the angle grinder is also used to grind at an angle.
The angle grinder name basically describes how the tool looks which is the head of the tool is at a 90-degree angle from the shaft of the angle grinder.
Angle grinders can be dangerous when not used safely and properly.
Also you must be alert and should wear gloves, safety glasses etc.
I highly recommend wearing gloves when using an angle grinder because one time I did not wear gloves and for some reason the grinding disc shattered and cut my finger a little.
Thankfully it did not cut my finger really bad but after that accident I started wearing gloves when using the angle grinder.
Also never remove the guard on the angle grinder as it's there for safety and to protect you and always set the angle grinder down upside down.
Make sure the angle grinder has shut off first and then set it down.
When not changing the angle grinder discs it's also best to unplug the angle grinder and then plug it back in.
