CCMT09T302 NS9530 — Turning insert for finishing, 0.2 mm radius, 7° clearance (Tungaloy)

CCMT09T302 NS9530 is an ISO‑standard finishing insert in uncoated cermet, optimised for external and internal turning of steel where low cutting forces and high surface quality are required.

• Finishing grade for steel with sharp cutting edge
• Uncoated cermet for excellent surface finish
• 0.2 mm nose radius for fine detail turning
• 7° clearance and 80° rhombic geometry

Consistent finishing results with low cutting effort

The NS9530 grade is an uncoated cermet developed for finishing operations on steel, delivering a consistently sharp cutting edge and low cutting forces. This combination reduces the tendency for chatter during light passes and produces a tighter surface texture, which can shorten or eliminate downstream polishing. The material behaviour lends itself to continuous cutting, making the insert especially suited to stable set‑ups and short‑cycle precision parts where repeatable surface quality is a priority.

Geometry that supports precision and repeatability

A defined 0.2 mm nose radius and 7° clearance angle provide a balance between fine profile definition and edge strength. The rhombic 80° geometry offers versatility for both external and internal operations while the specified thickness (3.97 mm) and hole style (cylindrical hole with single‑side countersink 40°–60°) ensure secure clamping in standard ISO holders. These geometric choices translate into controlled tool engagement, predictable wear progression and reliable dimensional stability across batches.

Practical application guidance for mills and job shops

Select this finishing insert when aiming for high surface quality on turned steel components with small depths of cut. The NS9530 finishing grade performs best in continuous cuts and when combined with a suitable single‑sided chipbreaker selected to match workpiece material and machining stability. For mixed‑production environments, pairing the insert with a rigid holder and optimised feeds will maintain the sharp edge life and reduce the need for frequent regrinds or index changes.

System compatibility and installation considerations

Being an ISO‑standard turning insert, compatibility with the toolholder is determined by form, clearance angle, tolerance class, fastening method, size and thickness. Typical system build‑up includes the ISO insert, a matching external holder or boring bar, an underlay/shim and a clamp set with replacement screws. Confirm holder seating and screw torque to preserve repeatable clamping forces; correct mounting prevents micro‑movement and supports predictable chip formation and tool life.

FAQ

What materials is this insert recommended for?
The CCMT09T302 NS9530 insert is recommended for turning steel, with the NS9530 grade optimised as a finishing sort for continuous cuts and small depths of cut.

How does the 0.2 mm nose radius affect surface finish?
A 0.2 mm nose radius provides fine profile definition and contributes to an improved surface texture when the CCMT09T302 NS9530 is used in finishing passes under stable cutting conditions.

Is this insert compatible with all ISO holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the CCMT09T302 follows ISO standards and requires a matching holder and clamp set for secure mounting.

What chip control does the single‑sided chipbreaker provide?
The single‑sided chipbreaker is designed to assist in controlled chip formation during finishing operations, supporting continuous cutting and predictable edge behaviour with the NS9530 grade.

Which cutting conditions suit this cermet grade best?
NS9530 performs best in continuous cuts with small material removal and is intended for operations prioritising surface quality and low cutting forces rather than heavy interrupted cuts.
