SPGM 120308 NS9530 — Tungaloy turning indexable insert, square 12 mm, cermet finishing grade

The SPGM 120308 NS9530 is an ISO‑standard square insert designed for finishing operations in steel turning, offering a sharp edge and low cutting forces for excellent surface quality

• ISO square insert 12 mm, 3.18 mm thick
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for superior surface finish
• Single-sided chipbreaker, 11° clearance

High-quality finishing through cermet edge control

The uncoated cermet grade NS9530 delivers a consistently sharp cutting edge, optimised for fine finishing of steel components. Its composition supports stable cutting at small depths of cut and during continuous feed conditions, which reduces the risk of built-up edge and improves repeatability. This results in a high surface finish and lower rework rates, helping to keep production runs predictable and efficient. The result is predictable part quality with less manual polishing or secondary operations.

ISO compatibility and secure seat for repeatable machining

Designed to the ISO designation SPGM120308, the insert’s geometry and tolerance ensure compatibility with standard external holders and boring bars when form, relief angle and fastening match. Key dimensions — 12 mm size, 3.18 mm thickness and 0.8 mm corner radius — combine with an 11° clearance to give a stable cutting position and accurate tool projection. The cylindrical locating hole and square format aid repeatable clamping and quick index changes, so setups are faster and concentricity is maintained across tool changes.

Application-focused advantages for turning operations

As a finishing grade, this insert excels in external and internal turning where low cutting forces and fine surface requirements are paramount. The single-sided chipbreaker is tuned for predictable chip formation in continuous cuts; selecting the matching chipformer and holder stability will extend edge life and maintain surface integrity. The insert is particularly suited to steel finishing tasks where minimised vibration and precise geometry deliver measurable time savings and consistent part quality.

FAQ

Which materials is this insert intended for?
The SPGM 120308 NS9530 is formulated as a finishing grade for steel and is recommended where a sharp edge and low cutting forces are required.

Is the insert suitable for both external and internal turning?
Yes, the square ISO geometry and the single-sided chipbreaker make the insert suitable for external and internal turning operations when matched to an appropriate holder.

What are the critical dimensions to check for holder compatibility?
Check the 12 mm size, 3.18 mm thickness, 0.8 mm corner radius and 11° relief; these determine fit and clamping in standard ISO SPGM toolholders.

How does the NS9530 cermet grade affect surface finish?
The uncoated NS9530 cermet provides a sharp, wear‑resistant edge that reduces built-up edge and promotes a superior surface finish in finishing cuts.

Does the insert require a specific chipbreaker orientation?
The insert uses a single-sided chipbreaker; orientation and holder stability should be selected to match the intended feed and depth of cut for consistent chip control.
