Microdrill VHM Drilling Tools Design: - shaft-integrated power chamber up to a drill Ø of 2.95 mm - sufficient coolant supply even at lower pressure VHM coated 6×D 140° ICS UNI - three times greater oil volume at the same pressure - increased drilling speed - longer tool life Cutting data - efficient chip removal - special spiral shape for optimal chip transport 10 - cooling, lubrication and carrying away of the chips Note: Set pilot hole with 102401, 102403 or 102416, resp. l2 d1 (k5) d2 (h6) 102425 MIKRON TOOL, CrazyDrill Cool, 6 × D, with internal cooling 102427 MIKRON TOOL, CrazyDrill Cool, 6 × D, eXedur RIP, with internal cooling d1 l1 l2 d2 d1 l1 l2 d2 Type 102425 102427 Type 102425 102427 mm mm mm mm mm mm mm mm 0075 0.75 51.5 6.8 3 1 0290 2.90 68.5 26.1 4 1 0080 0.80 51.5 7.2 3 1 0295 2.95 68.5 26.6 4 1 0085 0.85 51.5 7.7 3 1 0300 3.00 73.0 27.0 6 1 0090 0.90 51.5 8.1 3 1 0305 3.05 73.0 27.5 6 1 0095 0.95 51.5 8.6 3 1 0310 3.10 73.0 27.9 6 1 0100 1.00 55.0 9.0 4 1 0315 3.15 73.0 28.4 6 1 0105 1.05 55.0 9.5 4 1 0320 3.20 73.0 28.8 6 1 0110 1.10 55.0 9.9 4 1 0325 3.25 73.0 29.3 6 1 0115 1.15 55.0 10.4 4 1 0330 3.30 75.5 29.7 6 1 0120 1.20 55.0 10.8 4 1 0335 3.35 75.5 30.2 6 1 0125 1.25 55.0 11.3 4 1 0340 3.40 75.5 30.6 6 1 0130 1.30 57.0 11.7 4 1 0345 3.45 75.5 31.1 6 1 0135 1.35 57.0 12.2 4 1 0350 3.50 75.5 31.5 6 1 0140 1.40 57.0 12.6 4 1 0355 3.55 75.5 32.0 6 1 0145 1.45 57.0 13.1 4 1 0360 3.60 77.5 32.4 6 1 0150 1.50 57.0 13.5 4 1 0365 3.65 77.5 32.9 6 1 0155 1.55 59.0 14.0 4 1 0370 3.70 77.5 33.3 6 1 0160 1.60 59.0 14.4 4 1 0375 3.75 77.5 33.8 6 1 0165 1.65 59.0 14.9 4 1 0380 3.80 77.5 34.2 6 1 0170 1.70 59.0 15.3 4 1 0385 3.85 79.0 34.7 6 1 0175 1.75 59.0 15.8 4 1 0390 3.90 79.0 35.1 6 1 0180 1.80 61.0 16.2 4 1 0395 3.95 79.0 35.6 6 1 0185 1.85 61.0 16.7 4 1 0400 4.00 79.0 36.0 6 1 0190 1.90 61.0 17.1 4 1 0410 4.10 80.5 35.3 6 1 0195 1.95 61.0 17.6 4 1 0420 4.20 80.5 36.1 6 1 0200 2.00 63.0 18.0 4 1 0430 4.30 80.5 36.1 6 1 0205 2.05 63.0 18.5 4 1 0440 4.40 80.5 37.0 6 1 0210 2.10 63.0 18.9 4 1 0450 4.50 80.5 37.8 6 1 0215 2.15 63.0 19.4 4 1 0460 4.60 80.5 38.6 6 1 0220 2.20 63.0 19.8 4 1 0470 4.70 84.5 39.5 6 1 0225 2.25 63.0 20.3 4 1 0480 4.80 84.5 40.3 6 1 0230 2.30 65.0 20.7 4 1 0490 4.90 84.5 41.2 6 1 0235 2.35 65.0 21.2 4 1 0500 5.00 84.5 42.0 6 1 0240 2.40 65.0 21.6 4 1 0510 5.10 84.5 40.8 6 1 0245 2.45 65.0 22.1 4 1 0520 5.20 84.5 41.6 6 1 0250 2.50 65.0 22.5 4 1 0530 5.30 84.5 42.4 6 1 0255 2.55 65.0 22.7 4 1 0540 5.40 88.0 45.4 6 1 0260 2.60 66.5 23.4 4 1 0550 5.50 88.0 46.2 6 1 0265 2.65 66.5 23.9 4 1 0560 5.60 88.0 47.0 6 1 0270 2.70 66.5 24.3 4 1 0570 5.70 88.0 45.6 6 1 0275 2.75 68.5 24.8 4 1 0580 5.80 88.0 46.4 6 1 0280 2.80 68.5 25.2 4 1 0590 5.90 88.0 47.2 6 1 0285 2.85 68.5 25.7 4 1 0600 6.00 88.0 48.0 6 1 www.precitool.de 10/49
