NEWS 2018 – POLLEDRI’S ANTI-VIBRATION COUNTERSINKS

New range of 3-flutes 90° POLLEDRI’S Countersinks with ASYMMETRIC GEOMETRY OF THE CUTTERS
These POLLEDRI’S Countersinks, thanks to their asymmetric cutting geometry that reduces axial force compared to traditional one, guarantee a significant reduction in vibrations, and a consequent better finish of the flaring.
Their rectified angle at 20 ° and at constant value, guarantees the reduction of friction and allows numerous regrinding.
Chip evacuation is significantly improved due to the large distance of the grooves between the three cutting edges.

Available from Diameter 6,3 to Diameter 31,0, in HSS-E 5% Co, HSS-E 5% Co + TiN and 5% Co + TiAlN up to 3500HV, these POLLEDRI ANTIVIBRATING COUNTERSINKS further enrich the wide range of POLLEDRI Countersinks to solve any problems related to countersinking
