Special geometry with extremely unequal spacing and matching cutting edge preparation. Radially relief ground. Flutes ground from solid. Newly developed special TiAIN coating for long service life. High-precision countersink, produced with tight manufacturing tolerances similar to DIN 335-C. Advantage: Very smooth cutting throughout the entire countersinking operation. Chatter-free running for perfect results and optimum tool service life. Application: High-precision countersinks for production of exact, round 90° counterbores. Very well suited to virtually all materials. Advantage in comparison to HSS countersinks especially in the field of high-tensile steels and because the working life is several times longer. Shank tolerance h6 - suitable for mounting in hydraulic chucks or shrink-fit chucks. 150388 Extremely unequal spacing (cutting edges arranged at unequal intervals) Suitable for/ v( m/min Alu plastics oSQ£L, Alu cast > 10% Si X < 500 N X < 750 N X < 900 N X < 1100 N X <1400 N X <55 HRC X < 60 HRC X <65 HRC IN0X <900N INOX >900N Ti >850 N GG G) CuZn Graphite CRP CRP Uni 6 6 ISO code nri N N P H K N nri 150388 80 80 60 65 60 50 40 10 12 25 20 15 35 70 External 0 150388 smallest countersink 0 for holes from T for countersunk screws DIN 7991 i i tk.uiuii juiiu lui uiut v.uui iituiiiiu i imi 90" L f mm TIAIN mm mm/rev 6,3 106.92 1.5 45 5 M3 0.04 8,3 115.83 2 50 6 M4 0.05 10/4 120.29 2.5 50 6 M5 0.05 12,4 126.23 2.8 56 8 M6 0.06 16,5 154.94 3.2 60 10 M8 0.08 20,5 177.21 3.5 63 10 M10 0.1 25 204.93 3.8 67 10 M12 0.12 31 242.55 4.2 71 12 Ml 6 0.12 219
