A device and method for reaming a flight gap of a drill flight of a drilling tool includes a base carriage displaceably mounted along a mast of a drilling apparatus. A reaming element engages the flight gap so soil adhering to the rotating drilling tool is scraped off by the reaming element. A support arm holding the reaming element is movably mounted between a retracted position where the reaming element is spaced apart from the drilling tool and a reaming position where the reaming element engages the flight gap. The support arm pivots about a pivot axle parallel to a longitudinal drilling axis of the drilling tool. The support arm is additionally mounted on the base carriage parallel to the longitudinal drilling axis of the drilling tool to be deflectable from a basic position, and is resiliently held in the basic position by means of a bias spring.
