Built from Glass Filled Nylon (GFN) and other quality materials, the Mac Tools 1/2" Cordless Impact, No. BWP050, is powered by Dewalt's advanced battery, switch and electronic technology to deliver consistent performance. The battery flexibility allows techs to conveniently interchange batteries within the Mac Tools and Dewalt product families. Featuring the 20V Max battery platform, the BWP050 features a die-cast aluminum housing for reduced weight and maximum durability, and a feather throttle for maximum operational control. The ergonomic handle design provides a forward center of gravity for superior balance and control. Socket change is quick and easy due to the square drive anvil with hog-ring. Other features include an anti-marring bumper to protect the tool and work surfaces, an LED worklight for close quarters work, and a one-handed forward/reverse lever and variable speed switch with electronic brake for maximum control.
