TNMG 160412 NS9530 Tungaloy turning insert — uncoated cermet finishing grade

TNMG160412 NS9530 is a triangular ISO insert designed for external and internal turning, optimised for finishing passes on steel with a sharp cutting edge and precise chip control

• Uncoated cermet grade NS9530
• Sharp cutting edge for fine finishing
• Double-sided chipbreaker design
• ISO triangular insert with 60° included angle

Superior surface finish with reduced cutting forces

The NS9530 grade is an uncoated cermet developed for finishing applications on steel, delivering a consistently fine surface quality and reduced tendency to built-up edge. The composite nature of cermet provides a hard, wear-resistant cutting face while maintaining lower friction than conventional grades; this combination results in lower cutting forces and stable finishing passes. For manufacturers aiming to improve part finish without complex process changes, the geometry and grade support predictable results on continuous cuts and small depths of cut.

Easy integration into ISO turning systems

Designed as an ISO-standard insert, the geometry corresponds to the ISO 160412 family and a 60° included angle, ensuring compatibility with a wide range of external holders and boring bars. The insert includes a cylindrical centre hole for secure screw clamping and a robust seating with standard tolerances, simplifying tool changeover and stock management. Compatibility depends on holder form, clearance, tolerance class, fastening and insert thickness; the standardised format facilitates swift retrofit into existing tooling systems and supports efficient production workflows.

Chip control and dimensional features explained

The double-sided chipbreaker profile promotes controlled chip formation during finishing operations, reducing interruptions and improving process reliability. Key dimensions such as the 4.76 mm plate thickness and 16 mm inscribed circle size offer rigidity for light to moderate finishing cuts, while the 1.2 mm corner radius balances edge strength with the need for fine surface integrity. These measurable attributes allow planners to calculate approach parameters and predict tool behaviour under specified cutting conditions, helping to reduce trial-and-error at setup.

When this finishing grade is the right choice

Select this insert for continuous turning of steel components where a high-quality finish and repeatable results are required. The combination of a sharp cutting edge and the NS9530 composition is particularly suitable for operations with small feeds and shallow depths of cut, where aesthetic finish and dimensional fidelity are priorities. Process engineers seeking to shorten secondary finishing or polishing operations will find the grade advantageous, as it can lower rework rates and contribute to a more economical production flow.

FAQ

What materials is this insert suited for?
The TNMG160412 NS9530 insert is formulated as a finishing grade for steel; the uncoated cermet composition is optimised for low cutting forces and superior surface finish on ferrous materials.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening method and insert thickness; the ISO 160412 designation ensures fitment with standard triangular turning holders designed for TNMG inserts.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm corner radius provides a balance between edge strength and the ability to produce fine surface finishes; it is recommended for small to moderate finishing cuts where dimensional accuracy and surface integrity are important.

Is the insert suitable for both external and internal turning?
Yes. The insert’s geometry and double-sided chipbreaker make it suitable for both external and internal turning applications when matched with an appropriate external holder or boring bar.

What clamping method does the insert require?
The insert features a cylindrical centre hole and is intended for screw clamping with the standard mounting hardware used for ISO turning inserts.
