The present invention relates to a stone processing chisel. More specifically, the stone processing chisel is installed in an air conditioner injecting a compressed air and is pressurized by injection of the compressed air and strikes and processes a stone. The stone processing chisel has an insertion rod having an insertion groove in a lower portion thereof to enable the insertion groove to be inserted into a coupling protrusion part of the air conditioner. A strike head striking the stone is formed in an upper portion of the insertion rod and is formed to be coupled with and separated from the insertion rod to be replaced. The stone processing chisel prevents the strike head and the insertion rod from being separated by vibration due to the striking when the strike head and the insertion rod are coupled to each other. |
