The DEWALT 23.4 Lb. SDS max demolition hammer with shocks is designed for professional chipping, demolition and chasing applications with a variety of masonry materials including brick, concrete and stone. This SDS max demo hammer features a heavy-duty 14.0 Amp motor that protects against overload, a soft-start feature that prevents bouncing by slowly building-up to the desired impact rate, and an active vibration control that neutralizes rebound vibration and lowers vibrational impact to the operator. Other features include an SDS max tool holder with rubber dampers for easy insertion and removal of SDS max chisels, a chisel indexing dial for accurately rotating the chisel to any of 12 different positions, and an adjustable side handle that rotates 360-degrees. This heavy-duty hammer also features a non-air pumping beat piece and spring-loaded dust seals to prevent dust from entering the machine while in use.
