Convex cutting edges give the tool its extremely high rigidity and ensure an optimal chip fracture. The flute profile is optimised for hard machining and evacuates the swarf safely from the hole. The Guhring hard drill is available as standard tool with straight shank to DIN 6535 HA in the diameter range from 2.6 to 14.1 mm. d1 d2 l1 l2 l3 mm 2.600 6.000 62.00 20.00 36.00 3.000 6.000 62.00 20.00 36.00 3.400 6.000 62.00 20.00 36.00 4.000 6.000 66.00 24.00 36.00 4.300 6.000 66.00 24.00 36.00 5.000 6.000 66.00 28.00 36.00 5.100 6.000 66.00 28.00 36.00 5.600 6.000 66.00 28.00 36.00 6.000 6.000 66.00 28.00 36.00 6.900 8.000 79.00 34.00 36.00 7.100 8.000 79.00 34.00 36.00 8.000 8.000 79.00 41.00 36.00 8.600 10.000 89.00 47.00 40.00 9.100 10.000 89.00 47.00 40.00 10.000 10.000 89.00 47.00 40.00 10.400 12.000 102.00 55.00 45.00 10.600 12.000 102.00 55.00 45.00 11.100 12.000 102.00 55.00 45.00 12.000 12.000 102.00 55.00 45.00 14.100 16.000 115.00 65.00 48.00 Cutting rates at 3 x D with Guhring no. 1946 Hardness Cutting speed vc Feed rate HRC 40...48 HRC 48 62 40 m/min 30 m/min f (mm/rev): f (mm/rev): drill 0 in mm 2.6 0.032 0.025 3.4 0.040 0.032 4.3 0.050 0.040 5.1 0.050 0.040 5.6 0.050 0.040 6.9 0.070 0.055 7.1 0.070 0.055 8.6 0.090 0.070 9.1 0.090 0.070 10.4 0.110 0.090 10.5 0.110 0.090 11.0 0.120 0.100 14.1 0.120 0.100 GUHRING 677 Hardened steel
