with Internal Coolant Channels without Internal Coolant Channels

Interchangeable adapters can carry PENTA inserts with 5 threading corners for the
production of external threading and can be mounted on different holders. These adapters
are available with internal channels for high pressure coolant or without internal coolant
channels. There are many types of holders that are suitable to carry these adapters when
the holders differ in their adaptation and designation. These tools are suitable for various
interchangeable adapters for external threading, external grooving, external parting and
external turning.
