TNMG 160408 NS520 – Turning insert by Tungaloy for finishing and light machining

TNMG160408 NS520 is an ISO-format triangular indexable insert designed for external and internal turning where surface quality and dimensional accuracy are paramount

• ISO TNMG160408 triangular insert
• Cermet NS520 for fine finishing
• Double-sided chipbreaker for chip control
• Cylindrical-hole design for secure clamping

Precision finishing for demanding turning operations

The NS520 grade is a cermet or coated cermet formulation optimised for finishing to light machining of steel, prioritising surface finish and dimensional accuracy. This composition delivers a combination of hardness and wear resistance that reduces built-up edge and promotes uniform flank wear, so repeatable part quality is achievable across batches. Thanks to the ISO-standard geometry, integration into established tool systems is straightforward and predictable.

Stable chip control and consistent clamping for productivity

A double-sided chipbreaker pattern supports controlled chip formation in a variety of cutting conditions, reducing the risk of long, entangling swarf and improving process stability. The insert’s cylindrical hole and precise seat dimensions enable secure fastening in compatible holders; compatibility is determined by form, relief angle, tolerance class, clamping and plate thickness. The triangular profile also offers three indexing edges per insert, which contributes to efficient use and lower tooling cost per edge.

Clear specifications to simplify tool selection and setup

ISO designation and measurable parameters make selection and setup transparent: the insert matches holders rated for TNMG-style plates and key dimensions such as 16 mm inscribed circle, 4.76 mm thickness and 0° relief are fixed for reliable seating and cutting geometry. The 0.8 mm corner radius supports fine finishing passes while maintaining edge strength. These defined specifications reduce guesswork when configuring toolholders and machining programmes, helping to keep cycle times consistent.
