    摘要： A separate drilling head has a distal end which contacts the material to be drilled, and a proximal end which is attached to a drive mechanism. The drive mechanism drives the separate drilling head into the material. The separate drilling head is forcelockingly secured in a thin-walled hollow anchor tube, and the separate drilling head includes a hard metal cutter element, and a substantially axially-oriented, axial stop shoulder at the proximal end that passes into a circumferentially closed, outer cone.

    摘要： A curable, two-component mortar composition is described, which is based on a curable epoxide resin, at least one reactive diluent for the epoxide resin, an amine curing agent and one or more inorganic fillers, as well as, optionally, curing catalysts, rheological aids, thixotropizing agents, stabilizers, dispersants, agents to control the reaction rate and wetting agents, the amine curing agent of the curable epoxide resin and the reactive diluent being kept separate from one another to inhibit any reaction, wherein the mortar composition contains a cross-linking reactive diluent, which has functional epoxy groups with an epoxy functionality of at least 2. The mortar composition is used to fasten anchoring means in boreholes.
