EWN 04-152 Boring Heads

Variable tool length adjustment of the tool holder
Higher rigidity, and in turn better cutting performance, can be achieved by keeping tool assemblies as short as possible. EWN centric boring heads feature variable length adjustment of the tool holders which ensures the shortest and most rigid tool assembly.

Fine balanced when tool carrier is set in the center position
Tool holders with adjustable insert holders permit diameter setting on the insert holder. The heavy tool holder remains in the center position and does not create any imbalance. The imbalance created by the insert holder is in most cases insignificant.

Large dial disc for a parallax-free reading
Thanks to the use of a vernier scale, diameter adjustments of 0.001 mm can be executed precisely.
