CCGT09T308 NS9530 Tungaloy indexable insert for turning — uncoated cermet, 0.8 mm radius

CCGT09T308 is an ISO‑standard rhombic indexable insert engineered for finishing operations in turning, offering a sharp cutting edge and a geometry optimised for continuous cuts and fine surface finishes

• ISO‑normed rhombic turning insert 09T308
• Uncoated cermet grade NS9530 for finishing
• 0.8 mm corner radius for fine surface finish
• Cylindrical hole with single‑side countersink

High‑precision finishing with lower cutting forces

The combination of the NS9530 cermet grade and the rhombic geometry provides a sharp cutting edge that reduces cutting forces and improves surface quality during finishing passes. The small 0.8 mm corner radius permits fine detail and tight tolerance control while the 7° clearance contributes to a stable shear zone and reduced rubbing. For manufacturers seeking consistent, high‑quality turned surfaces, this insert reduces the need for subsequent finishing operations and supports efficient cycle times.

Reliable fitment and repeatable clamping for productivity

As an ISO‑standard indexable insert, compatibility with holders is determined by shape, clearance angle, tolerance class, fastening, size and thickness; this ensures predictable positioning and straightforward integration into existing tooling systems. The cylindrical hole with single‑side countersink (40°–60°) provides secure location and positive clamping, which translates to repeatable component accuracy and fewer scrap parts. Choosing the correct holder and torque for the clamping screw completes a system that is reliable under continuous turning.

Application guidance and process benefits for steel finishing

This grade is a dedicated finishing sort for steel: it is designed for continuous cuts and small depths of cut where a superior surface finish is the priority. The single‑sided chipbreaker supports controlled chip flow for stable machining of steels under typical finishing feeds. In practice, that means fewer passes to achieve the required Ra value, predictable tool life for planning, and improved process economy. For engineers evaluating tooling options, this insert is a measured choice where surface integrity and dimensional consistency matter.

FAQ

What steels is this insert suitable for?
The CCGT09T308 NS9530 Tungaloy insert is optimised as a finishing grade for steels, offering a sharp edge and low cutting forces suited to continuous finishing cuts.

How does the NS9530 cermet grade affect surface finish?
NS9530 is designed for high surface quality: the cermet composition and sharp cutting edge of the insert produce finer finishes and reduced need for secondary operations.

Which holders fit this insert?
Fitment depends on ISO‑standard geometry: holders matching the rhombic form, size 09, thickness 3.97 mm, and the 7° clearance will be compatible; ensure correct tolerance class and clamping method.

What is the purpose of the countersunk hole?
The cylindrical hole with a single‑side countersink provides secure location and positive clamp engagement, improving repeatability and reducing assembly variability during tool changes.

Is this insert suitable for interrupted cuts?
The CCGT09T308 is primarily a finishing grade optimised for continuous cuts; for heavy interrupted cutting, a more robust grade or chipbreaker may be preferable.
