What is an Angle Grinder, and How Does it Work?

The angle grinder is a rotary power tool that means it requires the power to rotate the wheel/disc. The wheel/disc cuts, grinds, and polishes while powered to move. As for size and shape, it is the size and shape of the disc. And the task to accomplish determines the type and size of the disc.

As we know that angle grinder is a power tool, it obviously needs a power source to run. There may be as many as three types of power sources to empower the disc to run. And the power sources include:
