TPGT 16T304 NS520 turning insert – Tungaloy, 60° triangle, 0.4 mm radius

TPGT16T304 NS520 is an ISO‑standard triangular indexable turning insert designed for finishing and light turning of steel, prioritising surface quality and dimensional accuracy.

• ISO‑standard triangular insert
• Cermet NS520 for fine finishing
• 0.4 mm corner radius for accurate edges
• 11° clearance angle for stable cutting

High‑precision finishing with a cermet grade optimised for steel

The insert is produced in the NS520 cermet grade, developed for finishing to light machining of steel where surface quality and repeatable dimensions matter. Cermet materials combine ceramic hardness with metal toughness, reducing built‑up edge and delivering an improved surface when compared with conventional grades in comparable operations. As a result, expect consistent wear behaviour and improved component appearance where dimensional tolerances and surface integrity are critical.

Geometry and mounting that support stable turning

The triangular 60° geometry and a 0.4 mm corner radius give a reliable contact zone and help maintain edge strength during finishing passes. Mounting uses a centre hole with a cylindrical bore plus a single‑side countersink (40°–60°), which, together with a plate thickness of 3.97 mm, ensures positive clamping in compatible holders. Compatibility depends on form, 11° clearance angle, tolerance class, fastening method, size and thickness, so selection of a matching external holder or boring bar is essential for predictable performance.

Practical benefits for shopfloor productivity

Equipped with a one‑sided chipbreaker, the insert assists chip control during external and internal turning, lowering the risk of chip interference in automated setups. The ISO‑normed design simplifies tooling specification and inventory management across a production line. Where repeatable finishing and reduced rework are priorities, this indexable solution supports shorter setup times and a steady process window, helping maintain throughput without sacrificing component quality.
