Punch, stepped, rectangle with radiused corners, ~DIN 9844
Material:
HSS
Order No 2250.3□□□.
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 piercing die bush are ordered together. This reduces the fitting time and the risk of an edge break during operation.
