The BH24 gasoline breaker has been engineered to have increased power and improved performance over previous models. The piston and striker have a reconfigured shape to reduce weight and increase velocity, reducing hand/arm vibration by up to 50%. Powered by a 2-cycle WM 80 engine, it is suited for breaking concrete floors, walls, sidewalks, brickwork, and similar materials. Wacker Corp. 800-770-0957.
