Abstract

A suction-extraction attachment for an insertion tool includes a housing, a bearing unit, and a suction-extraction opening. The housing has an end-side opening that is configured to accommodate the insertion tool. The bearing unit is configured to mount the suction-extraction attachment on the insertion tool. The suction-extraction opening is configured to couple the suction-extraction attachment to a suction-extraction device. The end-side opening and the suction-extraction opening form a transporting channel. The suction-extraction attachment is configured to be mounted on the insertion tool via the bearing unit in an axially movable and rotatable manner such that a position of the suction-extraction attachment relative to the insertion tool alters as a drill-hole depth increases.
