ANTI-VIBRATION COUNTERSINKS 90° 3 FLUTES
in HSS-E HRC 65 5% Cobalt + TiN 2300HV.

From Ø 6.3 to Ø 31.0 to perform 90° countersinks from M3 to M16 on almost all materials.
The ANTI-VIBRATION countersinks 90° with 3 flutes are suitable for performing both deburring and countersinking. Among other uses, they are particularly suitable for making seats for screw heads.
The ANTI-VIBRATION countersinks with three cutting edges HSS-E 5% COBALT, are made exclusively according to the international standard DIN 335. They are obtained by starting from HSS M35 cobalt steel bars, which gives them exceptional wear resistance.
If used with an adequate lubricant, three-edge countersinks have a long life.

The AlTiCN coating makes them particularly suitable for intensive high-performance machining

MADE WITH ASYMMETRIC CUTTING GEOMETRY, they reduce the axial force compared to traditional countersinks, with a consequent reduction in tool vibrations and a better countersinking finish.
