Abstract
A guide rail for use in drilling, cutting and grinding tools has two first and second pairs of guide surfaces (1, 2, 3, 4) arranged opposite one another relative to a first axis of symmetry (S1). Each pair of first and second guide surfaces are V-shaped and are laterally spaced apart and extend in the direction of a central axis of the guide rail. A second axis of symmetry (S2) extends perpendicularly to the first axis of symmetry (S1). An additional third pair of guide surfaces are disposed on opposite sides of the second axis of symmetry (S2) and have a flattened arrowhead-like sloping roof-shaped configuration and extend in the direction of the central axis.
