description PROBLEM TO BE SOLVED: To provide an apparatus for perforating light-weight cellular concrete which facilitates the discharge of chips of the concrete and entirely eliminates of clogging of the chips on the way. SOLUTION: A cutting tip for perforating a hole in light-weight cellular concrete is provided at the end opened with the inner hole 14 of a cylindrical body 7, and a tube 18 for supplying the air to the vicinity of a cutting tip from the base end 20 of the body 7 is inserted into the body 7. A suction source 32 for sucking the chips of the concrete communicates with the hole 14 of the body 7. A rotatably driving means is coupled to the body 7. Air supply means 33 may communicate with the tube 18.
