The DeWALT L-Shape Demolition Hammer is powered by a 13.5 Amp motor. The hammer delivers 8 joules of impact energy. The hammer is ideal for work on concrete and masonry walls, floor and wall channeling and removing plaster and tile from floors, falls and ceilings. The variable speed dial allows the user to reduce power for better performance in brittle substrate materials. The Active Vibration Control Technology offers less user fatigue and better productivity.
