Abstract
A support apparatus for a hand guided drill tool, especially a drill tool having diamond cutting elements, is provided. The support apparatus includes a movable support arm having at its free end a stand off piece for receiving and guiding a drill bit relative to a surface to be drilled. The movable support arm is telescopically movably mounted to a base element which has a travel stop member for engaging the support arm to prevent further extension thereof beyond its fully extended position. A damping element comprised of two plate shaped elastomeric portions is mounted on the support arm to damp the engagement of the support arm by the travel stop member and thereby avoid undesirable damage and collision noises.
