PTFNRL External Turning Tool Holder for TNMG Inserts

The PTFNRL external turning tool holder is engineered to meet the requirements of OEM manufacturers who demand consistency, durability, and repeatable machining results. Designed as a dedicated TNMG insert tool holder, it supports negative triangular inserts and is optimized for facing-oriented cutting applications.

This turning tool holder adopts a proven lever type clamping mechanism that securely locks the insert while allowing fast and reliable insert replacement. The 90° approach angle enables accurate face turning and square shoulder machining, ensuring controlled cutting forces and excellent dimensional accuracy on end faces.

Manufactured from high-strength alloy steel and subjected to controlled heat treatment processes, the PTFNRL tool holder delivers high rigidity and long service life under continuous production conditions. Precision-machined insert seats and contact surfaces ensure stable insert positioning and repeatable indexing, which are critical for automated machining lines and batch manufacturing.

As a standard external turning tool holder within the PTFNR series, the PTFNRL design complies with ISO specifications and is compatible with a wide range of TNMG negative triangular inserts from global suppliers. This standardized design helps OEM customers simplify tooling selection, reduce inventory complexity, and maintain consistent machining performance across multiple machines.
