A depth stop is mounted on the casing of a drilling machine and includes a clamping lever with a bore through which an elongated rod extends. The rod acts as the stop. Lugs attached to the casing pivotally support the clamping lever. The lever has a clamping surface which engages the surface of the casing in the clamped position. The clamping surface extends circumferentially of the axis of the bore in the lever and is arranged eccentrically relative to the axis. |
