TPGT 130308 NS520 turning insert, cermet, 60° – Tungaloy

A TPGT130308 NS520 ISO-standard triangular turning insert designed for finishing to light turning operations on steel components.

• ISO triangular insert with 60° geometry
• NS520 cermet for finishing steel
• 0.8 mm corner radius for fine edge quality

Improved surface finish and dimensional control for finishing operations

The NS520 grade is a cermet developed for finishing to light machining of steel, delivering a fine surface finish and stable, uniform wear. With a focus on dimensional accuracy, the cutting edge maintains its profile over longer runs, reducing rework and part rejection. The rounded 0.8 mm corner radius supports consistent edge strength while producing a fine surface texture, so fewer downstream operations are required. This results in improved process reliability and predictable component quality for series production.

Seamless integration into ISO tooling systems for faster setup

Designed to the ISO plate family, the insert features a 60° triangular geometry and a defined 11° relief angle that match common turning holders. The cylindrical hole with a 40°–60° countersink ensures secure clamping and repeatable seating, reducing setup variation between jobs. Because the insert follows ISO norms for form, tolerance and thickness, it can be integrated into existing toolholders and boring bars without modification, shortening changeover time and increasing machine uptime for job shops and production lines.

Durable carbide substrate and chip control for predictable productivity

Built on a robust carbide substrate with a 3.18 mm plate thickness and a single-sided chipbreaker, this insert balances edge life and chip formation for light finishing cuts. The single-sided pocketing aids controlled chip flow in finishing passes, while the triangular shape and 60° geometry provide reliable corner indexing when reusing unused edges. The overall package supports cost-effective, repeatable turning where surface quality and stable wear are priorities.

FAQ

What materials is the insert suitable for? The NS520 grade insert is intended primarily for finishing to light machining of steel, with the cermet chemistry focusing on surface quality and even wear.

How does the 0.8 mm corner radius affect the cutting result? A 0.8 mm corner radius provides a balance between edge strength and fine surface finish; the geometry supports consistent dimensional accuracy during finishing passes.

Is the insert compatible with existing ISO toolholders? Yes. The ISO-compliant geometry, 11° relief angle and the cylindrical hole with countersink make the insert compatible with standard ISO turning holders that accept triangular plates.

What chip control can be expected with this chipbreaker? The single-sided chipbreaker is tuned for finishing operations; it promotes short, manageable chips and stable flow during light cuts.

How many edges can be indexed on this triangular insert? The triangular form allows multiple usable corners; indexing frequency will depend on cutting conditions and toolpath strategy.
