TCGT 090204 NS520 Tungaloy turning insert — cermet finishing, 60° triangular

The TCGT090204-01 NS520 is an ISO‑standard triangular turning insert designed for finishing to light machining of steel, optimised for high surface quality and dimensional control.

• Cermet grade NS520 for fine finishing
• ISO‑standard triangular insert, TCGT form
• 0.4 mm corner radius for accurate contours
• Centre hole with 40°–60° countersink

Reliable finishing and consistent dimensional control

The combination of the NS520 material and the triangular TCGT geometry delivers a stable cutting edge for finishing operations. The cermet composition emphasises surface finish and dimensional accuracy, providing even wear and predictable results over repeatable cycles. This makes the insert particularly suited to parts where tolerance and appearance matter, such as turned housings or precision shafts.

Flexible holder compatibility and secure clamping

As an ISO‑standard insert, the geometry and mounting features ensure straightforward integration into compatible external holders and boring bars. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness, which simplifies selection and reduces setup time. The 7° clearance and 2.38 mm thickness help maintain stable clamping and predictable load distribution during turning.

Consistent chip control for improved productivity

Equipped with chipbreaker 01, the insert promotes short, controllable chips during finishing and light machining. The optimised chip formation reduces built‑up edge and contributes to consistent wear, supporting higher process reliability and steady productivity. Choosing a finishing‑grade insert like this one minimises rework and helps maintain cycle‑time targets in batch production.

Application guidance and material suitability

The insert is intended for turning operations on steel in finishing to light machining applications. Its triangular shape and 0.4 mm corner radius are ideal for fine contouring and profile work. The centre hole design—cylindrical hole with a one‑sided countersink (40°–60°)—ensures precise seating in a wide range of ISO holders. Available in cermet or coated cermet variants, the grade focuses on improving surface integrity while delivering steady edge life.

FAQ

What is the primary application for this insert?
The TCGT090204-01 NS520 insert is intended for turning, specifically finishing to light machining of steel, where surface quality and dimensional control are priorities.

Which holders will accept this insert form?
Compatibility depends on the ISO TCGT form and matching holder geometry; the insert’s form, 7° clearance, thickness and fastening type must match the external holder to ensure secure clamping.

What advantages does the NS520 grade provide?
NS520 is a cermet grade from Tungaloy that emphasises improved surface finish, steady edge life and uniform wear, making it suitable for precision finishing operations.

What are the key geometric data to check before ordering?
Check the 60° included angle, 0.4 mm corner radius, 2.38 mm thickness, centre hole with cylindrical hole plus one‑sided countersink (40°–60°), and the TCGT090204-01 designation.

How does the chipbreaker influence machining?
The chipbreaker 01 on this insert promotes short, controllable chips during finishing and light machining, contributing to consistent tool life and reduced risk of built‑up edge.
