<p>In order to guide the drill on the one hand and remove the developing dust on the other hand when setting plug holes in building walls, a shell (18) is provided which has a sealable margin (17) lying in one plane. A support (21) for the drill is rigidly connected to this shell (18). In addition, the jig contains an air passage (9) which on the one hand is fluidically connected to a suction opening (20) near the support (21) as well as to the shell (18) and which on the other hand leads into a connection for a suction device. <IMAGE></p> |
