NEWS 2019 – 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. Continue reading

INTERCHANGEABLE SYSTEM

BACK SPOTFACING SYSTEM

ALBERO DI GUIDA PER FRESE IN TRAZIONE

GROUP 6-9-14-20-30-40
in carburized and hardened steel
The arbors specially devised for our back-spotfacing cutters are made in Case Hardened steel HRC 60.
All arbors have a threaded hole at the end of the taper to allow the locking of the arbor to the machine by means of a drawbar.
Alternatively, they can be used with the tang end and locked to the machine with the positioning slot if available.
The MT 3-4-5 have a locking slot to DIN 1806 whilst the MT 1-2 have no locking slot. Continue reading
