TNMG 160408 NS520 turning insert — cermet finishing, 0° clearance (Tungaloy)

The TNMG160408 NS520 turning insert is an ISO‑standard, triangular indexable plate for finishing to light turning of steel, engineered for superior surface quality and reliable dimensional stability.

• ISO‑standard triangular insert
• Cermet grade NS520 for finishing
• 0.8 mm corner radius for fine edges
• Double‑sided chipbreaker with cylindrical hole

Consistent finishing and repeatable accuracy

The grade NS520 is designed for finishing to light turning of steel, prioritising surface finish and dimensional accuracy. As a cermet‑based cutting material, it promotes uniform wear behaviour which reduces scatter in part tolerances and lowers rework rates. The result is more predictable process outcomes and improved throughput when fine surface integrity is required.

Geometry engineered for stable turning cycles

The triangular plate with a 60° included angle and 0.8 mm corner radius enables a fine cutting edge suited to finishing passes. The 0° clearance and double‑sided chipbreaker support controlled chip formation and allow two effective cutting edges per insert, optimising tool utilisation. The central cylindrical hole provides secure clamping; together these features maintain stable cutting conditions and reduce vibration during light finishing operations.

System compatibility and simple selection

Supplied as part of the ISO‑turning insert family, compatibility with holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The insert thickness of 4.76 mm and nominal size 16 mm follow ISO conventions, facilitating selection of matching external holders or boring bars. Select the chipbreaker and the NS520 grade in line with workpiece stability and the required surface specification for best results.

Operational advantages and application guidance

Using a cermet finishing insert reduces the number of passes needed to reach target roughness, which can shorten cycle times in high‑mix production. The combination of cermet chemistry and optimised chip control supports consistent edge life under finishing conditions. For parts where tight dimensions and a high‑quality surface are priorities, this insert is a reliable option; for uncertain holder fits or atypical materials, consult application data or technical advice to confirm the correct chipbreaker and clamping arrangement.
