Description

PTUNR/L Boring Bar with Internal Coolant, Internal Turning Tool Holder IC

The PTUNR/L internal turning holder with internal coolant supply is the ideal solution for precise and process-reliable internal machining. With a 95° approach angle and robust P-clamping, it provides secure fixation of TN..1604 indexable inserts and minimizes vibration even under demanding cutting conditions. The integrated internal coolant system (IKZ) directs coolant precisely to the cutting edge, reducing heat generation and ensuring efficient chip evacuation. This increases insert tool life and guarantees consistently high surface quality.

The precisely machined insert seat ensures exact repeatability during insert changes and maintains the dimensional accuracy of machined components. Thanks to its stable design and optimized coolant channel geometry, the PTUNR/L boring bar is ideal for use on modern CNC lathes as well as conventional turning centers.

With the PTUNR/L internal turning holder, you invest in a powerful and durable tool that combines precision, process reliability, and efficiency for high-performance internal machining.

Bohrstange für Innendrehen, mit Kühlung

Die interne Kühlung ist bei schwer zerspanbaren Materialien wirklich ein Vorteil, Werkzeug bleibt länger scharf und die Bohrung wird rund. Serienbearbeitung bei uns unproblematisch gelaufen.

Innenstange die Schnellwechsel-Innenstange IK ordentlich

Schnellwechselsystem mit IK innen, Plattensitz und Kühlung passen zusammen. Werkzeug wird bei uns in wechselnden Werkstoffen und Bearbeitungssituationen eingesetzt, die Ergebnisse sind durchgängig sauber und wiederholbar, Werkzeugaufnahme bleibt spielfrei.

Macht einen guten Job

Habe die Bohrstange für Schlichtaufgaben genutzt. Kühlung ist direkt an der Schneide, dadurch entstehen keine langen Problemspäne.

Innenstange mit Quickchange und Kühlung

Kombination aus Schnellwechsel und Innenkühlung. Bei häufigen Werkzeugwechseln und anspruchsvollen Aufträgen die beste Option. Sehr flexibel. Im Werkstattalltag bei wechselnden Aufträgen die flexible Wahl.
