PTGNR/L External Turning Tool Holder for TNMG Inserts

The PTGNR/L external turning tool holder is engineered for OEM manufacturers who require reliable machining performance, dimensional consistency, and long-term tooling stability. Designed as a dedicated TNMG insert tool holder, it supports negative triangular inserts and is optimized for facing-focused cutting applications.

This turning tool holder utilizes a proven lever type clamping mechanism that securely fixes the insert during continuous cutting while allowing quick and safe insert indexing. The 90° approach angle enables perpendicular tool engagement, ensuring accurate face turning and clean shoulder machining with controlled cutting forces.

Manufactured from high-strength alloy steel and processed through controlled heat treatment, the PTGNR/L tool holder offers excellent rigidity and resistance to deformation under medium to heavy cutting conditions. Precision-machined insert seats and reference surfaces ensure accurate insert positioning and repeatable machining results, which are essential for automated production lines and batch manufacturing.

As a standard external turning tool holder within the PTGNR system, the PTGNR/L design complies with ISO specifications and is compatible with a wide range of TNMG negative triangular inserts from major global insert suppliers. This standardization helps OEM customers streamline tooling selection, reduce inventory complexity, and maintain consistent machining performance across multiple machines.
