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. l 71 90 112 d1 / Order No d2 Pmin Gmax l1 / Order No r (Order Code character) (D) (F) (O) 3 / (1) 5 0.5 2.9 8 (1) 10 (2) 0.3 ● ● ● 4 / (2) 7 0.8 3.9 8 (1) 13 (3) 0.3 ● ● ● 5 / (3) 8.5 1 4.9 13 (3) 19 (4) 0.5 ● ● ● 6 / (4) 10 1.6 5.9 13 (3) 19 (4) 0.5 ● ● ● 8 / (5) 12 2 7.9 19 (4) 25 (5) 0.7 ● ● ● 10 / (6) 14.5 3.5 9.9 19 (4) 25 (5) 0.7 ● ● ● 13 / (7) 20 4.5 12.9 19 (4) 25 (5) 1 ● ● ● 16 / (8) 22 6 15.9 19 (4) 25 (5) 1 ● ● ● 2220.
