A mechanical breaker or chipping hammer used to demolish concrete, rock, or heavy slag. The nickname comes from the rapid, repeating strike action of the chisel bit, which resembles a bird pecking at wood. Operators mount large versions on excavators and use handheld versions for detail demolition.
