At 1 lb lighter than its predecessor, this saw combines the power and durability you expect from SKILSAW with jobsite-proven, pro-focused features. On top of our legendary worm drive, you get the best-in-class Dual-Field motor, engineered specifically by SKILSAW for saws. You have got your hands on the next evolution of the saw famous for cutting truer and lasting longer. This model even comes with a Diablo blade, just to make sure your SKILSAW is tough as nails right out of the box.
