Though the Impact Driver is lightweight and compact in size, it does not sacrifice performance with its brushless motor that delivers up to 1,825 in-lb of torque and 3,250 rpm for driving large-diameter screws. The impact driver is backed by a 3-year, limited warranty so you can buy with confidence.
