CNMG 120408 NS9530 Turning insert — Tungaloy

The CNMG120408 NS9530 is an ISO‑format turning insert designed for finishing operations on steel, offering a sharp cutting edge, low cutting forces and reliable chip control for continuous cuts.

• ISO CNMG 120408 format for universal holders
• Uncoated NS9530 cermet for superior finish
• Double‑sided chipbreaker for consistent chips
• Sharp cutting edge for low cutting forces

Consistent fine finishes for finishing turns

The uncoated NS9530 cermet grade is formulated to deliver a sharp cutting edge that lowers cutting forces and reduces vibration during finishing operations. In practice this means better dimensional control and a measurable improvement in surface integrity when turning steel at small depths of cut. The material's properties favour continuous cutting, making it particularly suitable for long, uninterrupted passes where a high‑quality surface is the primary outcome rather than aggressive material removal.

Secure fit and straightforward integration with ISO holders

The insert's ISO format ensures compatibility with standard CNMG pockets when the holder matches by form, clearance angle, tolerance class, mounting type, size and thickness. Key dimensions such as 12 mm inscribed circle and 4.76 mm thickness combine with a 0° relief angle and an 80° approach geometry to provide predictable seating and repeatable clamping. The 0.8 mm corner radius supports a balance between edge strength and fine finish, while the cylindrical hole ensures positive mechanical location for secure fastening.

Stable chip control and improved process economy

Featuring a double‑sided chipbreaker, the insert promotes reliable chip formation and evacuation under a range of feed rates common in finishing. This leads to fewer interruptions, reduced tool change frequency and improved spindle uptime — all pragmatic advantages in a production environment. The geometry and grade are optimised for steel finishing: lower cutting forces result in reduced power draw and less tool‑holder stress, contributing to overall process stability and a favourable cost‑per‑component ratio.

Practical notes on application and selection

The ISO‑standard plate is intended for turning applications where surface quality and edge definition are priorities. Select the NS9530 finishing grade for steels with continuous cutting characteristics and modest depths of cut; for interrupted cuts or highly abrasive materials, consider alternative grades or edge preparations. Compatibility depends on holder type and clamping system, so verify pocket form and screw style prior to assembly. The plate is rhombic in form and supplied with a cylindrical hole for secure fastening in standard CNMG pockets.

FAQ

What materials is this insert intended for?
The CNMG120408 NS9530 Tungaloy indexable insert is optimised for finishing operations on steel and delivers superior surface quality when used in continuous turning.

How does the NS9530 grade affect surface finish?
The NS9530 cermet grade used in the CNMG120408 insert provides a sharp cutting edge and low cutting forces, which together improve surface integrity and reduce the need for secondary finishing.

Which holder dimensions should be checked before fitting the insert?
Verify the pocket matches the CNMG ISO format, and confirm relief/clearance angle, tolerance class, mounting method, inscribed circle (12 mm) and plate thickness (4.76 mm) to ensure proper seating of the Tungaloy insert (SKU 6707285-Tungaloy).

Is the insert reversible or single‑use?
The rhombic CNMG120408 insert is double‑sided with a double‑sided chipbreaker, allowing rotation to a fresh cutting edge when one side is worn, thereby extending the effective tool life.
