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 hot upset-forged. Shaft and shoulder precision plunge-ground. Key flats parallel with longest size of shape, unless otherwise specified. Note: With kerf ≤ 0.04 mm, FIBRO rounds off sharp edges for shape 1 and shape 2 if the punch and piercing die bushing are ordered together. This reduces the fitting time and the risk of an edge break during operation. 269.
