CCMT09T302 NS9530 indexable turning insert — ISO finishing insert for turning, by Tungaloy

The CCMT09T302 NS9530 is an ISO‑standard indexable turning insert engineered for finishing operations on steel, offering a sharp cutting edge and low cutting forces for consistent surface quality.

• Uncoated cermet grade NS9530 for finishing
• 0.2 mm corner radius for fine detail
• ISO‑compatibility with standard holders
• Single‑sided chipbreaker for continuous cuts

Consistent finishing performance with low cutting forces

The uncoated cermet composition NS9530 is tailored for finishing passes on steel, delivering a high-quality surface finish while keeping cutting forces low. Cermet combines ceramic hardness with metal toughness, which reduces built-up edge and improves dimensional stability during continuous cuts. This makes the insert particularly suitable for applications with small depths of cut where surface integrity and tight tolerances are critical. The result is fewer secondary operations and predictable part quality.

Secure fit and geometry that supports precision turning

Designed to the ISO plate specification, the insert’s rhombic shape and 80° lead angle provide a stable seating in compatible holders. The plate includes a cylindrical hole with a single‑side countersink (40°–60°) to ensure correct clamping and repeatable positioning. The 3.97 mm thickness and tolerance‑compliant form aid in vibration dampening during external and internal turning, contributing to consistent chip flow and tool life across production batches.

Optimised chip control for continuous cutting conditions

The single‑sided chipbreaker is matched to the cermet grade and intended for continuous cutting modes, promoting predictable chip evacuation and minimising interruption during long runs. For finishing operations where minimal material removal and smooth chips are desirable, this chipformer reduces the risk of surface damage and eases downstream handling. Where intermittent cuts are expected, selecting an appropriate holder and cutting parameters will maintain the integrity provided by this insert design.

Practical benefits and process considerations for production workflows

Integrating this ISO‑format insert into a machining cell supports quick index changes and straightforward inventory handling. The 0.2 mm corner radius balances edge strength with the ability to produce sharp external contours, while the sharp cutting edge of the cermet grade reduces rubbing and work hardening on steel surfaces. For process planning, match feed rates and spindle speeds to the finishing nature of the grade and verify clamping rigidity to fully exploit the insert’s capabilities.

FAQ

What material applications is this insert optimised for?
The CCMT09T302 NS9530 is optimised for finishing operations on steel; the NS9530 cermet excels in continuous cuts where surface finish and low cutting forces are priorities.

Can the insert be used in standard ISO external turning holders?
Yes, the insert conforms to ISO plate geometry and is compatible with holders that match the form, clearance angle, tolerance class, fastening method, size and thickness.

How does the 0.2 mm corner radius affect component finish?
A 0.2 mm corner radius offers a balance between edge strength and the ability to machine fine details, improving surface integrity while avoiding excessive edge chipping.

Is the NS9530 grade coated or uncoated?
The NS9530 grade supplied for this CCMT09T302 is an uncoated cermet, optimised for sharp cutting edges and superior surface quality during finishing.

What clamping features ensure repeatable positioning of the insert?
The insert includes a cylindrical hole with a single‑side countersink (40°–60°), enabling secure clamping and repeatable seating when used with appropriate underplates and screws.
