Description

PTJNR/L Turning Tool Holder with Internal Coolant, External Turning 93°

This PTJNR/L clamping holder with internal cooling has been specifically designed for demanding external turning operations under serial production conditions. With a setting angle of 93°, the holder offers optimal cutting edge positioning for machining steel and cast materials – suitable for both roughing and fine finishing operations. The integrated internal cooling system ensures pinpoint coolant delivery directly to the cutting edge. This not only enables effective chip removal, but also significantly reduces thermal loads on both tool and workpiece – a clear advantage at high cutting speeds and prolonged cutting times.

Thanks to the advanced clamping mechanism (P-clamping), indexable inserts can be changed quickly and reliably. The tool holder body is made of high-alloy tool steel and undergoes a specialized quenching and hardening process that significantly increases wear resistance and protects the tool from microscopic cracking. This clamping holder stands for maximum process stability, minimized setup times, and high manufacturing efficiency – an indispensable tool for modern CNC turning operations.

Scope of delivery: 1 PTJNR/L holder (without insert) including accessories. Note: The illustration shows the right-hand version (PTJNR).

Drehhalter mit Innenkühlung bleibt stabil

Außendrehhalter 93° mit Kühlmittelkanal. Gerade bei Edelstahl zeigt sich der Nutzen spürbar, Schneide bleibt kühler. Bei Reparaturdrehen in zähen Werkstoffen eine gute Wahl. Bei uns in der Fertigung regelmäßig eingesetzt bei Edelstahl-Aufträgen, die Standzeit der Platten bleibt konstant gut und rechtfertigt den Aufpreis gegenüber einfachen Haltern.

Außendrehhalter mit Innenkühlung top

Der 93°-Außendrehhalter mit Innenkühlung macht auf einer Mazak QT-200 in 1.2312 Werkzeugrohlingen einen sehr sauberen Job. Die Kühlung kommt präzise zur Schneide und die Klemmung hält auch bei forscheren Zustellungen stabil. Gute Investition.

Klemmhalter mit Innenkühlung bewährt

Der Außendrehhalter mit integrierter Kühlmittelzufuhr bringt bei zähen Werkstoffen deutlich bessere Oberflächen, die Wendeplatten halten auch bei hohen Zustellungen stabil in Position.

Funktioniert im Einsatz

Hab den Drehhalter jetzt seit ein paar Wochen. Sauberer Schnitt, sauberes Schnittbild. Standzeit geht für den Einsatz völlig in Ordnung. Für den Preis kann man nicht meckern, Luft nach oben bleibt trotzdem.

Klemmhalter 93 Grad mit innerer Kühlung

Der Klemmhalter mit innerer Kühlung liefert Kühlmittel direkt an die Schneide, Plattenstandzeit wird spürbar länger. Für Dauereinsatz echt ein Vorteil, auch bei wechselnden Materialien bleibt die Bearbeitung ruhig und die Werkzeugkosten gehen pro Teil runter.

Die Innenkühlung bringt einen spürbaren Vorteil, Platten halten deutlich länger. Klemmung ist fest und der Drehmeißel läuft ruhig durch.

Innengekühlter Drehhalter überzeugt klar

Die innere Kühlung macht einen echten Unterschied, die Platten bleiben kühler und die Standzeit verlängert sich merkbar. Hab ihn auf der Haas ST-20 in 1.4301 eingesetzt, sehr zufrieden.
