TNGA 160408 NS520 — Turning insert (triangular, 60°) by Tungaloy

A TNGA 160408 NS520 insert designed for finishing and light turning of steel in multidirectional turning systems

• Cermet grade NS520 for fine surface finish
• Triangular insert with 60° cutting angle
• 0.8 mm corner radius for profile stability
• Compatible with AddMultiTurn multidirectional systems

Consistent finishing and dimensional control

The NS520 cermet grade is engineered for finishing to light machining of steel, prioritising surface finish and dimensional accuracy. Due to the fine microstructure of the cutting material, the insert produces a uniform wear pattern that helps maintain tolerances across long runs. This results in fewer rework cycles and more predictable component quality when high geometrical precision is required.

Multidirectional productivity for fewer setup changes

Built for the AddMultiTurn model series, the triangular form and 60° cutting geometry allow the insert to perform longitudinal turning, facing and profile operations without frequent tool changes. The multidirectional turning concept reduces idle time and increases machine utilisation, enabling a more streamlined production flow. Integration into a compatible holder and clamping system ensures secure positioning and repeatable cutting performance.

Geometry and clamping that support stable machining

A 0.8 mm radius at the cutting edge balances profile definition with edge strength, making the insert well suited to finishing contours and light profiling. The 4.76 mm thickness contributes to insert rigidity, while the cylindrical hole enables reliable clamping in common holder designs. The listed 0° clearance angle and triangular shape provide predictable contact conditions, helping to reduce vibration and maintain surface quality under standard finishing feeds.

Material design and practical application notes

The insert is manufactured from cemented carbide with a cermet / coated cermet specification in grade NS520, which combines wear resistance and improved surface results compared with conventional grades. The design intentionally includes no chipbreaker, aligning it with finishing tasks where chip control is less aggressive and surface integrity is paramount. When applied in finishing and light turning of steel, the insert delivers even wear, consistent part finish and reproducible dimensional results.
