摘要： A tool for setting self-cutting undercut anchors (6) in boreholes (B) in a receiving material (G) includes anchors (6) formed of an axially extending anchor rod (7) with a conically shaped surface at a leading end of the rod widening in the setting direction, and an axially extending rotatable sleeve (9) laterally enclosing the anchor rod and which is axially displaceable against the conically shaped surface for effecting radially outward spreading of cutting tabs located at the leading end of the sleeve. The cutting tabs form an undercut (U) in the inner surface of the borehole (B) as the sleeve is rotated. The tool has a rotatable propelling part (2) for the sleeve (9) of the undercut anchor (6) and a trailing end (3) of the propelling part is arranged for insertion into a chuck of a rotary hammer drill. The propelling part (2) cooperates with a support element (4) arranged to be supported by the surface of the receiving material (G) in which the borehole (B) is formed. The support element (4) has a receptacle (5) for the trailing end of the anchor rod in which the anchor rod can be axially fixed. The propelling part (2) can be displaced axially relative to the support element.

摘要： An axially extending expansion anchor or dowel has an anchor body (2) with a first end region to be inserted first into a borehole (B) in a receiving material (G) and a trailing second end region in which a load can be applied. The first end region has an axially extending expansion region with at least two expanding tangs (7) separated from one another by axially extending slots. The first end region has a opening (11) into which an expanding body (12) is displaceable axially for radial expansion of the tangs (17). The axially extending opening (11) has an inner axially extending surface (10) closer to the axis of the anchor body and formed by a guide pin (9) of the anchor body (2) and an outer axially extending surface formed by the inner surface of the tangs (7). The expanding body (12) is basically sleeve-like shaped and has an inner surface which bears against the inner surface (10) of the opening (11). The outer surface of the expanding body (12) is, at least in part, wedge shaped. In the radially outwardly expanded state of the tangs (7), the expanding body (11) lies substantially flat against the inner and outer surfaces of the opening (11).
