Internal Tool Holder - PDUNR/L (93°) with cooling holes
The PDUNR/L internal tool holder with a 93° cutting angle and an internal cooling channel is an outstanding choice for precise profiling tasks. By directing the coolant straight to the cutting edge, it significantly aids chip evacuation and reduces thermal load. Specifically designed for professional turning operations using DN-style inserts, this boring bar provides a stable foundation for achieving high dimensional accuracy during internal machining.

Applications
This internal tool holder is primarily designed for demanding profile turning. It performs exceptionally well when boring tight tolerances or machining complex internal contours where reliable chip removal is crucial.
Its robust construction and integrated cooling system make it highly suitable for modern CNC lathes, supporting efficient production in mechanical engineering and series manufacturing.
Special features
The secure pin lock clamping mechanism ensures that the insert remains firmly in place. This facilitates quick insert changes and maintains high stability throughout the process.
With its internal cooling channel, the coolant reaches the hottest part of the cutting zone directly. This feature protects the cutting edge and promotes a smooth workflow, particularly when machining deep bores.
