ABSTRACT:
A device for effecting a seal against an underlying surface (5) in conjunction with drilling a hole therein, comprising an inverted cup-shaped member (9,11) whose rim (23) is intended to sealingly abut the underlying surface around the site of the hole (3) to be drilled, and the bottom (11) of which remote from the underlying surface is provided with a hole (27) through which a drill (1) is able to pass in at least substantially sealing fashion in conjunction with a drilling operation. The inverted cup-shaped member includes a tubular, annular element (9), which constitutes a cup-wall element, and a plate-like cover member (11) which forms the bottom. The cover member (11) is removable and therewith exchangeable, and can be mounted on the annular element in an at least substantially sealing fashion in a number of mutually different rotational positions, and is provided with an excentric hole (27) for the drill (1). The annular element (9) is provided with a laterally extending arm element (13) which presents at its distal end a support (33) intended for co-action with the underlying surface (5). A suction attachment means (15) is arranged on the arm element (13) between the annular element and the support intended for co-action with the underlying surface, so as to enable the device to be fastened to the underlying surface with the annular element and the aforesaid support in abutment therewith. A fluid-supply connection (13,39) and/or a suction connection (51) is arranged to supply a fluid to the interior (29) of the annular element or to remove fluid and drill cuttings by suction from the interior of the annular element.
