Adhering element e.g. adhering pad, for adhering at subsurface, has cover which partially covers base, where base and cover are connected with each other to form collecting pocket for chipping material formed at subsurface during drilling

摘要

The element (10) has a base (12) and a cover (20) partially covering the base, where the base and the cover are connected with each other, so as to form a collecting pocket (26) for a chipping material (62) formed at a subsurface (100) during drilling. A rear surface (16) of the base is turned away from the subsurface, which has one adhering surface. The element is made of paper or plastic foil. An adhesive surface is formed in the surrounding portion of a throughhole (30) on a front surface (14) of the base.
