SNGG 120404 NS9530 indexable insert for turning — Tungaloy

SNGG120404-01 NS9530 is an ISO-standardised turning indexable insert intended for precision finishing in steel turning applications

• NS9530 finishing cermet grade for steel
• Sharp edge for superior surface finish
• ISO SNGG 120404, square 12 mm format
• 0.4 mm corner radius for fine profiling

Exceptional finishing with reduced cutting forces

This insert combines an uncoated cermet composition with a finishing geometry engineered for low cutting loads. The finishing grade NS9530 produces a sharp cutting edge that reduces ploughing and minimises burr formation, which in turn improves throughput by cutting down secondary finishing. For operations with continuous cuts and small depths of cut, this characteristic yields a high surface finish and consistent part quality while keeping cutting forces low. The material behaviour of cermet is explained by its ceramic-rich microstructure: it sustains a keen edge at finishing speeds and resists built-up edge formation on steel, so less rework is required and cycle reliability is enhanced.

ISO compatibility for fast integration and predictable set-up

As an ISO-design insert, compatibility with toolholders is defined by form, clearance angle, tolerance class, fastening method, size and thickness. The SNGG format and its square 12 mm footprint permit straightforward mounting in standard external holders or boring bars; the insert features a cylindrical hole for secure clamping and a defined 0° clearance geometry for accurate tool orientation. This standardisation reduces set-up time and simplifies inventory management across machines. Selecting the correct chipbreaker and insert grade for the workpiece and stability of the set-up ensures reliable chip control and stable cutting conditions, thereby increasing machine utilisation and reducing process variability.

Predictable tool life and process benefits from controlled geometry

The moderate corner radius 0.4 mm supports fine profiling and consistent corner form while reducing the risk of corner chipping in finishing passes. For steel turning, the grade delivers repeatable wear behaviour and good surface integrity when used at recommended feeds and speeds. The insert’s square form and 90° included angle make it well suited to both external and internal turning tasks where tight tolerances and good surface quality are required. Together these features lead to a predictable tool life, fewer tool changes and improved overall process efficiency — advantages that support lean production goals and stable part output.

FAQ

What materials is this insert intended for?
The NS9530 grade is designed primarily for finishing operations in steel; the SNGG120404-01 insert offers a sharp edge and low cutting forces for reliable steel turning.

Can this insert be used for both external and internal turning?
Yes, the square format and 90° included angle make the insert suitable for external and internal turning when mounted in the correct holder.

How does the 0.4 mm corner radius affect part quality?
A 0.4 mm corner radius gives a refined profile and improves surface integrity in finishing passes while reducing the risk of minor chipping under stable cutting conditions.

Is the insert compatible with standard ISO holders?
The insert follows ISO dimensions; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness — confirm holder specifications before mounting.

Does the grade require a coated surface treatment?
This offering is an uncoated cermet finishing grade (NS9530) optimised for sharp-edge performance in finishing, where coatings are typically not required.
