Hole making device capable of reducing a workload of piping cleaning

Provided is a hole making device capable of reducing a workload of piping cleaning. The hole making device (1) comprises: a hole making portion that performs a hole making processing on a workpiece (W); a mounting table (40) having a discharge chamber (43) disposed on the opposite side of the hole making portion relative to a mounting surface where the workpiece (W) is placed and configured to discharge dusts generated during the hole making processing by the hole making portion; a dust collector (20) that collects dusts from the discharge chamber (43); a piping (21A) connected to the dust collector (20) to form a suction path (SP1) for sucking dusts; and a recovery unit (50) that is detachably mounted to the piping (21A) in a manner intervening in the suction path (SP1), and is constructed to allow dusts to accumulate more easily compared to the piping (21A). The hole making device further comprise a pressure sensor that detects the pressure in the discharge chamber; and a control unit that provides a notifi
