Drill bush DIN 179 A 1.0718 carbonitrided, HRC

Guide bushings DIN 179 are characterized by the tight dimensional and positional tolerances in connection with the hardened and finely machined surface. As a result, they are suitable for extremely universal use in many applications. Holes with tolerance H7 are recommended for installing the bushings. In connection with the outer diameter of the bushing with a tolerance of n6, use of a transition adapter is recommended. For guide applications, combination with the guide pins GN 771.1 is recommended.
