CNMG120408 GT9530 Tungaloy turning insert — coated cermet, 0.8 mm nose radius

The CNMG120408 GT9530 is an ISO-format indexable turning insert designed for finishing and light universal turning of steel under stable machining conditions.

• Coated cermet grade GT9530
• 0.8 mm nose radius for fine finishes
• Rhombic ISO CNMG geometry
• Double-sided chipbreaker, with cylindrical hole

Consistent finishing and longer tool life from GT9530

The coated cermet GT9530 grade is engineered for stable finishing operations where surface quality and tool life are priorities. The combination of a wear-resistant coating and a cermet substrate reduces flank wear and supports steady cutting edges during extended passes, which results in fewer insert changes and more predictable cycle times. This makes the component particularly suited to high-quality external and internal turning where a fine surface finish is needed without compromising productivity.

Simple integration into ISO turning systems

Designed to the ISO CNMG geometry, the insert fits standard external holders and boring bars provided form, relief angle, tolerance class, clamping and thickness match. The insert’s rhombic shape and 80° cutting angle provide stable engagement and predictable chip flow; the cylindrical hole supports reliable clamping and accurate indexing. Using an ISO-compliant insert simplifies tooling inventories and reduces set-up time across machines, enabling a smoother production flow with compatible holders and spare parts.

Practical benefits for shop-floor decision-making

The modest 0.8 mm nose radius offers a balance between surface quality and tool strength, making the insert a practical choice for finishing and light general-purpose turning of steel. The 0° relief angle is consistent with typical CNMG applications and maintains cutting geometry for repeatable part dimensions. Because the insert is double-sided with a dedicated chipbreaker pattern, it extends usable edge life while preserving surface integrity — a tangible efficiency argument for batch runs and serial production.

FAQ

What is the primary application for this insert?
The CNMG120408 GT9530 Tungaloy turning insert is intended for turning, particularly finishing and light universal operations on steel where surface quality and longer tool life are required.

Which material is the insert made from and what coating does it have?
The insert is a coated cermet (GT9530) on a carbide substrate, combining wear resistance with improved surface performance for finishing cuts.

How does the 0.8 mm nose radius affect machining results?
A 0.8 mm nose radius promotes finer surface finishes while maintaining sufficient edge strength for stable turning; it is a practical compromise for high-quality external and internal turning.
