PTTNR/L External Turning Tool Holder for TNMG Inserts

The PTTNR/L external turning tool holder is developed for OEM manufacturers who require consistent machining quality, long tool life, and standardized tooling solutions. Designed as a dedicated TNMG insert tool holder, it supports negative triangular inserts and is optimized for precise facing and square shoulder operations.

This turning tool holder employs a proven lever type clamping mechanism that ensures secure insert retention under continuous cutting loads while allowing fast and convenient insert indexing. The 90° approach angle enables true perpendicular entry into the workpiece, making the PTTNR/L tool holder particularly suitable for face turning and accurate shoulder machining.

Manufactured from high-strength alloy steel and processed through controlled heat treatment, the PTTNR/L tool holder offers excellent rigidity and dimensional stability over long production runs. Precision-machined insert seats guarantee accurate insert positioning and repeatable cutting performance, which are essential for automated machining lines and batch production.

As a standard external turning tool holder compatible with ISO specifications, the PTTNR/L design aligns with common tooling systems such as the PTFNR series, allowing OEM customers to standardize insert usage and tooling layouts. It is fully compatible with a wide range of TNMG negative triangular inserts from leading global suppliers.
