TCGT110204 NS520 Tungaloy — ISO turning indexable insert for finishing, triangular 11 mm

TCGT110204 NS520 is an ISO-standard triangular turning insert designed for finishing to light machining of steel, supplied by Tungaloy

• ISO-standard triangular insert, 11 mm inscribed circle
• Cermet grade NS520 for superior surface finish
• 0.4 mm nose radius for accurate profiles
• With hole and 40°–60° countersink for secure fixing

Precision surface quality for finishing and dimensional control

The cermet NS520 grade is tailored for finishing and light machining of steel, delivering a stable wear pattern and excellent surface finish. Cermet combines ceramic hard phases with metallic binders to offer a fine cutting edge that resists abrasive wear while promoting consistent dimensional results. This makes the insert particularly suited to applications where tolerance adherence and component appearance are critical, such as shaft turning and final-pass profiling.

Built for reliable system compatibility and quick indexability

The insert follows ISO geometry and a standard fixing design, so compatibility with matched external holders and boring bars is determined by form, clearance angle, tolerance class, securing method, size and thickness. The triangular shape with a central hole and one-sided countersink (40°–60°) ensures stable clamping and predictable repeatability during index changes. For workshop workflows this reduces downtime and simplifies tool stocking.

Enhanced cutting performance via material and chip control

The cutting material is cermet (coated cermet available), offering a balance between edge retention and thermal stability for low- to medium-speed finishing. The one-sided chipbreaker geometry supports controlled chip formation for light turning operations, helping to avoid built-up edge and to maintain consistent cutting forces. Together, these attributes increase process reliability and contribute to longer intervals between insert changes.

Practical handling and set-up advantages for production environments

With an inscribed circle of 11 mm, a 0.4 mm nose radius and a plate thickness of 2.38 mm, the insert provides fine profile control while remaining robust under common finishing feeds. The 7° clearance angle minimises rubbing on the flank face and helps preserve the cutting edge. Marked ISO designation and the Tungaloy article number allow straightforward identification and reordering, facilitating tool management and inventory control in production settings.

FAQ

What materials is this insert suitable for?
The TCGT110204 NS520 Tungaloy indexable insert is optimised for steel finishing and light machining; the NS520 cermet grade provides consistent wear and good surface quality on common steel alloys.

Which operations suit this insert best?
This insert excels in external and internal turning where high surface finish and dimensional accuracy are required, such as final passes, profiling and fine facing.

How does the ISO designation TCGT110204 translate into geometry?
The ISO code indicates a triangular plate with an 11 mm inscribed circle, a 0.4 mm nose radius and a specific thickness and clearance geometry; the code enables selection of a compatible holder system.

Is the insert compatible with standard clamping systems?
Yes — the ISO-standard form, the central hole with countersink and the specified thickness ensure compatibility with matching external holders and boring bars when the holder matches form, size and tolerance class.

What advantages does the NS520 cermet grade offer over conventional grades?
NS520 cermet focuses on surface finish, dimensional stability and uniform wear; it maintains a sharp edge and reduces the risk of built-up edge during finishing passes, supporting repeatable part quality.
