Recently purchased this saw and received it from this vendor. Nice saw, bigger than I was expecting. If you are a serious user of a circular saw probably better to look at the 7-1/4" version but for most home owners this will be more than enough saw.
The DEWALT DCS391B 20V MAX 6-1/2" Circular Saw features a powerful 460 MWO, 5250 RPM motor that delivers power and speed to make the most demanding cuts with ease. A high strength and lightweight magnesium shoe provides jobsite durability for long-term cut accuracy, and an optimized rubber overmolded comfort grip delivers optimal balance and control.
