CCMT120408 NS9530 – ISO indexable turning insert for finishing, Tungaloy

The CCMT120408 NS9530 is an ISO‑standard indexable turning insert engineered for finishing cuts in steel, offering a sharp edge and a low‑force geometry for continuous cuts and superior surface finish.

• ISO‑standard CCMT form for broad holder compatibility
• Uncoated cermet NS9530 for superior surface finish
• Sharp cutting edge for low cutting forces
• Cylindrical hole + 40°–60° countersink for secure clamping

Precision finishing that reduces rework and improves part quality

The CCMT geometry combined with the NS9530 uncoated cermet grade focuses on delivering a high surface finish with minimal secondary operations. The cermet cutting material provides a sharp cutting edge that reduces ploughing and rubbing at the tool–workpiece interface, which in turn lowers the required cutting forces. For finishing processes and continuous cuts, this enables reduced vibration and more stable chip flow, translating into tighter tolerances and fewer scrapped components. The inherent wear characteristics of the grade are balanced to sustain surface quality across extended runs.

Geometry and mounting for reliable repeatability in production

The insert’s rhombic CCMT form with an 80° approach angle, 7° clearance, and a 0.8 mm nose radius is suited to fine finishing and small depth‑of‑cut operations. The 12 mm inscribed circle and 4.76 mm thickness ensure mechanical stability when paired with appropriate ISO‑compliant holders. The central cylindrical hole with a 40°–60° countersink provides secure clamping and repeatable positioning in the pocket, while the single‑sided chipbreaker controls chip shape for smooth evacuation. These features together reduce set‑up variation and support consistent part runs on conventional and CNC lathes.

Application guidance and process advantages for turning steel

Designed primarily as a finishing grade for steel, this insert performs best under continuous cutting conditions with modest feed rates and shallow cuts, where quality and surface integrity are priorities. The low cutting forces characteristic helps when machining long or slender parts, reducing deflection and improving dimensional accuracy. Selection of a rigid holder and correct seat geometry will maximise the benefit of the cermet edge and chipbreaker. When integrated into a stable machining cell, the insert contributes to higher productivity through fewer machine stops for rework and improved first‑pass yield.

FAQ

What materials is this insert intended for?

The CCMT120408 NS9530 is specified as a finishing grade for steel and is optimised to deliver superior surface quality on continuous finishing cuts.

Is the insert compatible with common ISO holders?

Yes; the rhombic CCMT form and ISO designation mean compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness.

What are the key geometry values to check when setting up the insert?

Important values include the 0.8 mm corner radius, 7° clearance angle, 4.76 mm thickness and the 12 mm inscribed circle to ensure correct seating and process stability.

How does the uncoated cermet grade affect machining performance?

The NS9530 cermet provides a sharp edge and low cutting forces, promoting a better surface finish and reduced tendency to work‑harden the machined surface during finishing operations.
