- Fit surfaces d1 and d2 ground
Cutting bushings DIN 9845 (Types A, B) are used, for example, in combination with cutting punches DIN 9861 in punching tools. When selecting the cutting bushing, it is necessary to consider the required cutting gap, which depends on the material to be punched and the material thickness. The diameter d4 is larger than the cutting bore d1 to enable reliable ejection of the punched part. If necessary, cutting bushings can be machined to give them an application-specific geometry.
Guide bushings DIN 9845 (Type C) are used as punch guide bushings. However, they are also suitable for guiding and positioning of guide pins, for example, as alternatives to drill bushings DIN 172/ DIN 179 when the tolerance range should be closer to the nominal dimension. When combined with a location bore with tolerance H7, the outer diameter of the guide bushing with tolerance n6 results in a transition fit.
