SNMG120404 NS9530 indexable turning insert — uncoated cermet, finishing grade (Tungaloy)

A SNMG120404 NS9530 indexable insert designed for high-quality finishing in turning applications, offering a sharp cutting edge and optimised chip control.

• Uncoated cermet finishing grade NS9530
• Sharp cutting edge for superior surface quality
• 0.4 mm corner radius for precision profiles
• Double-sided chipbreaker for consistent chips
• ISO SNMG120404 format with cylindrical hole

Delivering repeatable precision and superior surface finish

The NS9530 grade is an uncoated cermet developed for finishing steel, combining a ceramic-rich matrix with a metallic binder to keep a sharp cutting edge under continuous cutting conditions. This material mix results in low cutting forces and excellent edge retention, which directly translates into finer surface textures and reduced need for secondary finishing. For machining processes with small depths of cut and steady feed, the insert supports consistent part quality and minimises micro-variations on turned surfaces.

Stable chip control and secure clamping for predictable cycles

Chip control is achieved through the double-sided chipbreaker geometry and the insert’s square form with a cylindrical hole, ensuring reliable evacuation of chips during continuous turning. Compatibility with holders follows ISO conventions: the fit depends on form, relief angle, tolerance class, fastening method, size and thickness. The ISO SNMG120404 format facilitates quick replacement in standard SNMG external holders and boring bars, supporting short changeover times and predictable machining cycles.

Geometry tuned for finishing and flexibility in application

The insert’s 0.4 mm corner radius and 0° relief angle support delicate profile work and minimise cutting edge deflection, which is beneficial for producing tight tolerances and consistent form on external and internal contours. The square form (12 mm size) and a plate thickness of 4.76 mm provide a stable seating in the toolholder; the double-sided construction allows indexability, extending tool life before disposal. Select the appropriate chipbreaker and grade based on workpiece rigidity and the specific steel grade to maximise performance.

Process efficiency, repeatability and tool management

Using an uncoated cermet finishing grade reduces vibration sensitivity from lower cutting forces and often extends intervals between tool changes, improving uptime and throughput. The insert is part of a straightforward system set—indexable insert, matching external holder or boring bar, support shim/clamping kit and replacement screws—so stock and logistics remain manageable. Together, these factors contribute to cost-effective finishing, reliable batch-to-batch repeatability and a more efficient production flow.

FAQ

What materials is the SNMG120404 NS9530 suited for?
The SNMG120404 NS9530 Tungaloy insert is a finishing grade optimised for steel; the uncoated cermet composition excels in continuous cuts and small depths of cut typical for fine turning of steel components.

Which toolholders are compatible with this insert?
Compatibility follows the ISO SNMG120404 standard; holders must match the insert form, relief angle, tolerance class, fastening method, size and thickness—this ensures the SNMG120404 NS9530 insert seats securely in standard SNMG external holders.

Is the insert reversible and how many cutting edges are available?
The insert features a square form with a double-sided chipbreaker, allowing indexing of multiple edges; refer to SKU 6944753-Tungaloy or Manufacturer SKU TUN6944753 for the exact configuration and edge count.

How does the NS9530 grade control chips during finishing?
Chip control is achieved via the double-sided chipbreaker geometry combined with the insert’s sharp cutting edge; SNMG120404 NS9530 produces consistent chip flow under continuous feeds, supporting stable cutting and surface quality.

What does the grade designation NS9530 indicate?
NS9530 denotes an uncoated cermet finishing grade from Tungaloy, formulated for excellent edge retention, low cutting forces and high surface finish on steel components; it is intended for finishing operations rather than heavy roughing.
