DRILLING DEVICE

To provide a drilling device which enables reduction of a workload of pipe cleaning.SOLUTION: A drilling device (1) includes: an installation base (40) having a drill part which performs drilling to a workpiece (W), and a discharge chamber (43) which is disposed at the opposite side of the drill part with respect to an installation surface on which the workpiece (W) is installed and to which powder dust occurring when drilling is performed by the drill part is discharged; a dust collector (20) which collects powder dust of the discharge chamber (43); a pipe (21A) which is connected to the dust collector (20) and forms a suction path (SP1) for suctioning powder dust; and a recovery device (50) which is detachably attached to the pipe (21A) so as to be disposed in the suction path (SP1) and configured so that powder dust is accumulated more easily than in the pipe (21A).SELECTED DRAWING: Figure 1 【課題】配管清掃の作業負荷を軽減することが可能な穴明け装置を提供すること。【解決手段】穴明け装置（１）は、ワーク（Ｗ）を穴明け加工する穴明け部と、ワーク（Ｗ）を設置する設置面に対して穴明け部の反対側に配置され、穴明け部により穴明け加工された際の粉塵が排出される排出室（４３）とを有する設置台（４０）と、排出室（４３）の粉塵を集塵する集塵機（２０）と、集塵機（２０）に接続され、粉塵を吸引する吸引経路（ＳＰ１）を形成する配管（２１Ａ）と、吸引経路（ＳＰ１）に介在するように配管（２１Ａ）に対して着脱自在であり、配管（２１Ａ）よりも粉塵が滞留し易く構成された回収器（５０）と、を備えた。【選択図】図１
