Counterbore and pilot are clamped by one screw each, the counterbore is additionally protected against turning by means of a pin. Size 1/20; 2/25 - Plain Weldon shank to DIN 1835 B, with internal coolant supply. Application: For DIN counterbores, as well as with appropriate pilot / counterbore combinations for stepped holes or non-standard counterbores. For stepped through holes pilots are available ex works in 2 lengths so that these holes can be produced without a separate pilot hole drilling operation. 15 6720_1 /20_2/25 Modular counterboring system Coolant transfer hole No./ shank size a 156720 Counterbore range mm Bore 0H7 mm Hole length mm External 0 mm Length a mm Length b mm Modular counterboring system holder 01/10 72.07 5-9 7 12 14 45 - 0/10 62.17 8-16.5 10 18 18 42 - 63.56 8-16.5 10 18 18 42 49.5 1/12 75.83 14-27.5 14 20 24 55 - 1/20 79.79 14-27.5 14 20 24 55 - 1MK2 79.79 14-27.5 14 20 24 55 61 2/25 89.00 24-66 22 28 34.5 75 - 89.00 24-66 22 28 34.5 75 81 89.00 24-66 22 28 34.5 75 81 Parallel shank MT shank HSS Very good machining and ideal chip evacuation due to spiral flutes.
