The original worm drive Skilsaw, often called the saw that built America, just got better. At 1 lb. lighter than its predecessor, this saw combines the power and durability you expect from SKIL with jobsite-proven, pre-focused features. On top of our legendary worm drive, you get the best-in-class Dual-Field motor, engineered specifically by SKIL for saws. You've got your hands on the next evolution of the saw famous for cutting truer and lasting longer.
