The Roughneck Ground Breaking bar is ideal to be used in locations & jobs where a normal crowbar is not sufficient or a pick not accurate enough. This heavy-duty bar is made up of an inner solid crowbar with a chisel tip drop forged heat treated & hardened. A weight slides up & down the central bar & exerts blows on the target material. It is ideal for breaking up hard ground rocks concrete slabs asphalt etc. For extra impact the end stopper can be removed to allow the weight to drop from a greater height.
