TNGG 160408 NS520 triangular indexable insert for turning — Tungaloy

The TNGG160408 NS520 is a triangular indexable insert designed for multidirectional turning in the AddMultiTurn system, optimised for finishing to light machining of steel.

• Multidirectional turning capability
• Cermet grade NS520 for fine finishes
• Triangular geometry with 60° cutting angle
• Double-sided chipbreaker for even wear

Delivering consistent surface quality with fewer setups

The AddMultiTurn concept pairs a versatile holder design with interchangeable inserts to enable machining in multiple directions using a single tool system. The combination of this multidirectional setup with a cermet cutting grade reduces the need for frequent tool changes and complex fixturing, which improves process efficiency on batch and single-piece production runs. By integrating the insert into a stable clamping arrangement, the system supports predictable tool life and repeatable component geometry.

Material grade engineered for finishing and dimensional stability

The NS520 grade, a cermet or coated cermet option, is crafted for finishing to light machining of steel and focuses on surface finish and dimensional accuracy. Cermet substrates combine ceramic hardness with metallic toughness, which helps maintain a sharp edge during fine cuts and promotes uniform wear across edges. This results in reliable workpiece tolerances and reduced rework, particularly where an excellent surface texture is essential for subsequent processes.

Geometry that balances edge strength and cutting precision

The triangular insert features a nominal 60° cutting angle and a 0.8 mm radius, giving a compromise between edge robustness and fine-profile capability. The plate is double-sided and includes a double-sided chipbreaker, allowing two indexed edges per face and helping to distribute wear symmetrically. A cylindrical centre hole supports secure clamping in compatible holders, ensuring repeatable seating and stable cutting conditions even under intermittent engagement or profiling passes.

Practical applications and process benefits

Intended primarily for turning operations — including longitudinal, facing and profiling cuts — this insert is suited to shops seeking improved surface integrity with controlled material removal. The design benefits shops that prioritise consistent finishing results, reduced machine downtime, and predictable changeover behaviour. When paired with the AddMultiTurn holder family and a matching clamping system, the insert contributes to fewer tool assemblies, simplified inventory and a smoother production flow.
