These electric hammers feature a strong and sturdy high quality construction, and are available in multiple wattages. The use of this tool will make easy work of breaking through materials such as brick, concrete and granite.  The demo hammer uses electricity to mechanically power internal pistons, which work together to create the motion of the drill bit. When the trigger is activated, the repeated motion of the drill bit in conjunction with the pressure applied by the user enables the tool to break through hard materials.  The demo hammer is an alternative power tool to a jackhammer rental, and is ideal for industrial and demolition projects for breaking through materials such as brick, concrete, and granite and in general for environments where an air compressor is unavailable.
