I attached this thing to my "Saw Boss" which has  "9" amp motor. I buzzed through plywood, 2X4's and an assortment of stuff with little effort. You must remember this blade cuts less material so you are working a lot slower, as in really slow when compared to the other blades. I made excellent clean cuts with no problems at all, but then again the Saw Boss pulls "9" amps so it does not slow down for much. Never used this blade on my cordless so I don't know how that would work, but I would guess as soon as the blade slows down the project gets to be a real tedious.
