SNGG 120404 GT9530 turning indexable insert — 0.4 mm radius, 90° geometry (Tungaloy)

SNGG120404-01 GT9530 is an ISO‑standard turning indexable insert engineered for external and internal turning, optimised for stable finishing of steel components.

• Coated cermet GT9530 for durable finishing
• ISO‑standard SNGG 120404 form for wide compatibility
• 0.4 mm corner radius for fine surface quality
• Cylindrical hole and 90° geometry for secure clamping

Higher surface quality with extended tool life

The coated cermet GT9530 grade is aimed at finishing to light‑universal operations on steel where surface integrity and extended tool life are priorities. A cermet is a ceramic‑metal composite that combines high hardness with improved wear resistance; the applied coating enhances resistance to adhesive wear and supports longer tool life under stable cutting conditions. The result is fewer insert changes and more consistent batch quality, which supports efficient production planning and lower operating costs.

Reliable fit and secure clamping for repeatable results

Compatibility is determined by insert form, relief angle, tolerance class, clamping method, size and thickness; the ISO‑standard SNGG 120404 form ensures interchangeability with suitable holders. The insert features a cylindrical hole and a square shape with a 90° insert angle, paired with a 0.4 mm corner radius that assists in achieving fine surface finishes without compromising edge strength. The 4.76 mm thickness and the defined relief angle support secure clamping and repeatable positioning in standard ISO external holders, reducing setup variability and improving process stability.

Selection guidance and machining considerations

For best performance, match the GT9530 grade and the chipbreaker style to workpiece material and machine rigidity; the supplied chipbreaker code 01 is geared towards stable operations where consistent chip formation is required. In practice, this insert is suited to turning of steel under rigid setups, offering good surface finish in finishing passes. If vibration or interrupted cuts are anticipated, selecting alternative chipbreakers or adapting cutting parameters will maintain edge life. For customers needing help with parameter selection, Metav Werkzeuge can advise on optimal cutting data for specific machines and materials.

FAQ

What materials is this insert designed for?
The GT9530 grade is developed primarily for turning steel, offering good surface finish and extended life in stable finishing operations.

Can the insert be used for internal as well as external turning?
Yes, the ISO‑standard SNGG form and the insert geometry permit both external and internal turning when paired with the appropriate holder and stable setup.

How does the 0.4 mm corner radius affect the finish?
A 0.4 mm radius balances edge strength and surface quality: it smooths the transition between passes to improve finish while maintaining adequate robustness for finishing cuts.

What does the coated cermet GT9530 provide compared with conventional grades?
Coated cermet combines high hardness with a wear‑resistant coating, delivering enhanced finish quality and longer tool life in finishing tasks on steel under steady conditions.

Which chipbreaker should be chosen for interrupted cuts?
The supplied chipbreaker 01 is optimised for stable, continuous cuts; for interrupted cutting conditions, alternative chipbreaker geometries or adjusted cutting parameters are recommended to preserve edge integrity.
