TPMR110308 NS9530 ISO turning insert, cermet, 60° – Tungaloy

The TPMR110308 NS9530 is an ISO-format triangular turning insert engineered for fine finishing in external and internal turning, offering a sharp uncoated cermet edge for continuous cuts.

• Cermet grade NS9530 for fine finishing
• 60° triangular geometry for versatile turning
• Sharp cutting edge with low cutting forces
• 0.8 mm corner radius for consistent finish

High-quality surface finish with low cutting forces

The uncoated cermet grade NS9530 is designed for finishing passes where a smooth surface and low cutting resistance are priorities. Its sharp cutting edge reduces ploughing and heat generation, which helps to achieve improved surface roughness on steels during light, continuous cuts. By using a finishing-specific grade, the tool minimises rework and supports stable interchangeability between inserts, resulting in predictable results when small depth-of-cut settings are required. The emphasis on edge integrity and low forces supports quieter machining and longer tool life under recommended conditions.

Reliable ISO geometry for straightforward holder compatibility

Built to ISO standards, the insert’s 60° triangular form and 3.18 mm plate thickness ensure compatibility with a wide range of external holders and toolposts when form, clearance angle, tolerance class, clamping and size are matched. The 11° clearance angle and triangular shape facilitate positive seating in standard indexable holders, while the 0.8 mm corner radius provides a balance between edge strength and fine-detail turning. Because compatibility depends on multiple parameters, the standardised geometry simplifies tool inventory and replacement planning for production and maintenance teams.

Application guidance for efficient finishing operations

This insert is optimised for turning of steels in finishing operations and is particularly effective with continuous cutting and small feeds. The single-sided chipbreaker design supports predictable chip formation for light passes; selecting the appropriate chipbreaker and grade for material and stability will maximise productivity. For best results, pair the insert with a rigid clamping system and adjust cutting parameters to maintain low cutting forces and steady surface quality. If machining strategy requires different engagement or interrupted cuts, choose a matching chipbreaker and verify holder compatibility before production.

FAQ

What materials is this insert best suited for?
The NS9530 cermet grade is optimised for finishing on steels; the TPMR110308 insert delivers low cutting forces and a fine surface finish when used for continuous finishing cuts on steel components.

Can the insert be used for internal turning as well as external turning?
Yes, the triangular ISO form and 60° geometry make the insert suitable for both external and internal turning when paired with a compatible holder that matches the insert’s size, thickness and clamping method.

How should the corner radius be selected for finishing operations?
A 0.8 mm corner radius provides a compromise between edge strength and surface quality for finishing; for finer profiles or smaller radii, a different insert geometry with a smaller corner radius may be more appropriate.
