Punch, stepped, rectangular, ~DIN 9861 PUNCH, STEPPED, RECTANGULAR, ~DIN 9861 Material: HSS Order No 2239.3□□□. ASP 2023 Order No 2239.6□□□. Hardness: Shaft 64 ± 2 HRC Head 52 ± 5 HRC Description of FIBRO materials for tool and die components see at the beginning of Chapter E. Execution: Punch head heat compressed. Contact area, shaft and cutting form precision ground. The locating flat is designed parallel with the dimension P = 0°. Note: With kerf ≤ 0.04 mm, FIBRO rounds off sharp edges, if the punch and bush are ordered together. This reduces the fitting time and the risk of an edge break during operation.
