CNMG 120404 NS9530 turning insert — rhombic 80° cermet finishing insert — Tungaloy

CNMG 120404 NS9530 is a rhombic, ISO-format turning insert designed for finishing operations on steel where a sharp cutting edge and excellent surface quality are required.

• Cermet finishing grade NS9530
• Rhombic geometry, 80° included angle
• 0° rake and sharp cutting edge
• Double-sided chipbreaker with cylindrical hole

High-precision finishing with a cermet edge

The uncoated cermet grade NS9530 is developed for finishing cuts on steel, offering a combination of a stable cutting edge and low cutting forces. In practical terms this means improved dimensional precision and a finer surface finish on continuous turning passes. Cermet consists of ceramic particles bonded with metal, which gives a wear‑resistant, sharp edge suited to small depths of cut and steady feed rates. The result is reduced rework and longer stable surface quality compared with conventional grades in similar applications.

Easy integration into ISO turning systems for reliable process setup

The insert follows ISO geometry standards so compatibility with holders depends on form, relief angle, tolerance class, fastening, size and thickness rather than proprietary fittings. The rhombic geometry with an 80° included angle and a 0° rake provides predictable cutting engagement for external and internal turning. Key dimensions such as size 12, thickness 4.76 mm and a corner radius of 0.4 mm make selection and fixture straightforward, while the cylindrical hole and double-sided chipbreaker support secure clamping and two usable edges per index. These attributes simplify tool‑making logistics and reduce setup time in production.

Recommended use and practical benefits in production

This grade is a dedicated finishing insert for turning operations, particularly when smooth surfaces and tight tolerances are required in serial production. Select the double-sided chipbreaker and the NS9530 grade for continuous cutting on steels to benefit from stable chip formation and extended edge life. For mixed or interrupted cuts, evaluate holder stability and adapt cutting parameters: sharper edges favour reduced cutting forces but require steady machine and workpiece support. Choosing this insert supports process reliability and consistent part quality, helping to keep downstream finishing and inspection needs to a minimum.

FAQ

Is this insert suitable for finishing steel components?
The CNMG 120404 NS9530 insert is specified as a finishing grade for steel; the uncoated NS9530 cermet provides a sharp edge and low cutting forces ideal for continuous finishing passes.

How many cutting edges are available per insert?
The insert features a double-sided chipbreaker and a rhombic form, giving two usable edges per index before re‑orientation or replacement is required.

What holder characteristics are important for compatibility?
Compatibility depends on form, relief (rake) angle, tolerance class, fastening method, size and thickness; ensure the holder matches the ISO rhombic shape, 4.76 mm thickness and the cylindrical hole to secure the insert correctly.

Can the insert be used for internal turning?
Yes, the ISO rhombic format and sharp cermet edge suit both external and internal turning applications where finishing and surface quality are priorities.
