How Much Power does a Circular Saw or Skilsaw use

Circular Saw or Skilsaw: 932 Watts


  • A circular saw, or Skilsaw uses a powerful electric motor to spin a circular blade.
  • Uses a variable speed motor and trigger, so it uses a variable amount of power, up to about 932 watts. There is a note on the side of the saw that it produces a maximum of 2.4 hp. I can't see that happening.
