CPMT 120408 NS9530 Tungaloy indexable insert for turning — uncoated cermet, 80° approach angle

CPMT120408 NS9530 Tungaloy indexable insert is designed for finishing operations in turning and parting where low cutting forces and excellent surface quality are required

• Precision finishing with uncoated cermet
• Optimised for continuous cuts and light feeds
• Compatible with TungCut grooving and parting systems
• 11° relief and 0.8 mm radius for fine surface finish

Consistent, high-quality finishing for steel components

The combination of the uncoated cermet NS9530 and a fine 0.8 mm corner radius delivers low cutting forces and a noticeably high surface finish, especially in finishing passes on steel. The material's sharp cutting edge and controlled edge preparation reduce built-up edge and minimise cutting heat, which preserves component tolerances and reduces the need for secondary operations. As a finishing-grade insert it is well suited to continuous cutting conditions and small depths of cut, providing predictable dimensional results and reduced scrap rates.

Stable chip control that shortens setup and cycle time

A single-sided chipbreaker and a geometry tuned for finishing ensure stable chip formation even at low material removal rates. Stable chips improve tool life by avoiding irregular loading and reduce interruptions for chip clearing, supporting higher process reliability and shorter effective cycle times. The resulting consistency in machining feeds directly into improved throughput and easier process parameter replication across shifts and machines.

Seamless integration into the TungCut system family

Designed for use within the TungCut system, the insert fits standard holders, clamp elements and parting tools in the family, enabling quick tool changes and a modular setup. This compatibility supports flexible machining strategies — from external and internal grooving to parting-off and plunge turning — without the need for specialised tool bodies. The system approach simplifies inventory and tool management while maintaining high repeatability during multi-operation production runs.

Geometry and mounting details that aid process planning

Key specifications simplify fixture and process planning: an 80° approach angle, 11° relief angle, rhombic 12 mm size and 4.76 mm thickness for a compact cutting edge, plus a cylindrical hole with one-sided countersink (40°–60°) for secure clamping. These features support reliable seating and repeatable positioning in the toolholder, minimise vibration in light finishing cuts and facilitate consistent edge engagement. The combination of geometry and material characteristics makes this insert particularly effective where fine surface quality and dimensional control are priorities.

FAQ

What materials is this insert intended for?
The CPMT120408 NS9530 Tungaloy indexable insert is a finishing grade optimised for machining steel, offering low cutting forces and a sharp cutting edge suited to continuous cuts.

Is the insert coated or uncoated?
This insert uses an uncoated cermet grade (NS9530), selected for excellent surface quality in finishing operations.

Which toolholders or systems is the insert compatible with?
The insert is designed for the TungCut system family and fits compatible holders, clamp elements and parting tools used for grooving, parting and plunge turning.

What are the key geometric values to consider during setup?
Relevant values include a 12 mm size, 4.76 mm thickness, 0.8 mm corner radius, 11° relief angle and an 80° approach angle; the insert also has a cylindrical hole with a single-sided countersink for secure clamping.

Can the insert be used for internal and external operations?
Yes — the TungCut system application covers both external and internal grooving, parting and cut-off operations where the insert geometry fits the toolholder.
