BLUE-TEC coating for a further substantial increase in service life also when machining dry (no/less cooling)  4.3-11.5 mm solid carbide  12.4-31 mm brazed shank For countersinking in materials: • Abrasive and hard steel with a strength of over 1000 N/mm 2 • Grey cast iron over 240 HB • High-alloyed chromium steel such as stainless (V2A / V4A) • Acid resistant steel • Titanium and titanium alloys • All further steel sorts, cast iron, non ferrous metals ... where maximum tool life are desired. Solid carbide countersinks Art. 20 1755 comes with cylindrical shank. This countersink type is used mostly on CNC-machines with shrinking chucks. Shrinking chucks works only with cylindrical shank. Attention: Solid carbide countersinks should be only used on CNC machines. 1441 Cutting data Movie Countersinking per DIN 74 Art. d1  mm d3  mm l1 mm d2  mm Z AF BF o 4.3 1.3 40.0 4.0 3 – – o 5.0 1.5 40.0 4.0 3 M 2.5 – o 5.3 1.5 40.0 4.0 3 – – o 6.0 1.5 45.0 5.0 3 M 3 – I 6.3 1.5 45.0 5.0 3 – M 3 o 7.0 1.8 50.0 6.0 3 M 3.5 – o 7.3 1.8 50.0 6.0 3 – – o 8.0 2.0 50.0 6.0 3 M 4 – I 8.3 2.0 50.0 6.0 3 – M 4 o 9.4 2.2 50.0 6.0 3 – – o 10.0 2.5 50.0 6.0 3 M 5 – I 10.4 2.5 50.0 6.0 3 – M 5 o 11.5 2.8 56.0 8.0 3 M 6 – I 12.4 2.8 56.0 8.0 3 – M 6 Countersinking per DIN 74 Art. d1  mm d3  mm l1 mm d2  mm Z AF BF o 13.4 2.9 56.0 8.0 3 – – o 15.0 3.2 60.0 10.0 3 M 8 – I 16.5 3.2 60.0 10.0 3 – M 8 o 19.0 3.5 63.0 10.0 3 M 10 – I 20.5 3.5 63.0 10.0 3 – M 10 o 23.0 3.8 67.0 10.0 3 M 12 – I 25.0 3.8 67.0 10.0 3 – M 12 o 26.0 3.9 71.0 12.0 3 M 14 – o 28.0 4.0 71.0 12.0 3 – M 14 o 30.0 4.1 71.0 12.0 3 M 16 – I 31.0 4.2 71.0 12.0 3 – M 16 o Prices and time of delivery on request < 1400 N < 900 N > 10% Si 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
