I can’t add a whole lot to Rich’s comments, his pointing out that hand held tools are powered with universal motors and table saws use induction motors is the crux of the situation.

Induction motors are standardized by NEMA. The HP rating is determined by the long term temperature rise running on full load. With a relitively flat speed torque curve, an induction motor can deliver considerably more power than the nameplate rating for short periods of time. Some manufacturers like to call this “peak power”, however it has no meaning as far as NEMA is concerned.

Universal motors are not standardized. Manufacturers can pretty much tell you anything. Many of these motors are rated in amps, which gives you very little indication of HP.
