TPGT110204 NS520 Tungaloy turning insert — ISO triangular insert for finishing in turning

TPGT110204 NS520 Tungaloy turning insert is an ISO‑normed triangular insert designed for finishing to light turning of steel, optimised for surface quality and dimensional stability

• Cermet grade NS520 for high surface quality
• ISO triangular geometry with central hole and countersink
• 0.4 mm corner radius for fine finishing
• One‑sided chipbreaker for controlled chip formation

Achieve superior surface quality with a specialised cermet grade

The NS520 cermet composition is developed for finishing and light machining of steel, where surface integrity and dimensional accuracy are paramount. The fine, wear‑resistant cutting edge reduces built‑up edge and ensures more uniform flank wear, which directly improves component tolerance and reduces rework. For shops aiming to deliver consistent finishes on turned parts, the combination of the cermet substrate and the optimised edge preparation yields longer intervals between tool changes and more predictable process windows.

ISO geometry and secure clamping reduce setup risk

The ISO triangular form (TPGT) with a 60° included angle and a central hole with cylindrical bore plus one‑sided countersink means the insert seats reliably in ISO holders and boring bars. The defined 11° clearance ensures the correct tool‑to‑workpiece contact angle for finishing cuts, while the 2.38 mm plate thickness contributes to stable clamping. These established standards simplify tooling selection and lower the risk of mismatched assemblies, allowing quick changeovers and repeatable positioning across machines and operators.

Controlled chip flow and improved process stability

A single‑sided chipbreaker tailored to light cutting conditions promotes consistent chip segmentation and evacuation, which reduces vibration and heat concentration at the cutting edge. Stable chip control leads to better surface finish and longer edge life, and it supports higher feed rates without sacrificing part quality. Manufacturers seeking efficient, reproducible turning operations will benefit from the reliable chip formation and the consequent reduction in machine downtime and part inspection rejects.

FAQ

What workpieces is this insert best suited for?
The TPGT110204 NS520 insert is optimised for finishing and light turning of steel, where surface quality and dimensional accuracy are required.

How does the NS520 grade improve edge life?
The NS520 cermet composition reduces adhesive wear and provides a stable cutting edge, resulting in more uniform wear and longer usable edge life during finishing operations.

Is the insert compatible with standard ISO holders?
Yes; the TPGT geometry with central hole and countersink is designed for compatibility with standard ISO triangular holders and appropriate clamping sets.

Which feature ensures fine surface finishes?
A combination of the 0.4 mm corner radius, the cermet cutting material, and the tailored chipbreaker delivers the fine finishes expected in finishing cuts.

Can this insert be used for heavier roughing cuts?
The insert is specified for finishing to light machining; for heavy roughing, a grade and geometry designed for higher mechanical loads should be chosen.
