CCMT 09T308 NS9530 ISO rhombic turning insert for finishing by Tungaloy

CCMT09T308 NS9530 is an ISO rhombic turning insert optimised for finishing operations on steel with a sharp cutting edge and one-sided chipbreaker.

• Uncoated cermet NS9530 finishing grade
• Sharp cutting edge for high surface quality
• One-sided chipbreaker for continuous cuts
• ISO-compatible rhombic 09 insert

Consistent finishing performance on steel components

The uncoated cermet grade NS9530 is formulated as a dedicated finishing material for steel, delivering a sharp cutting edge that reduces cutting forces and promotes a finer surface finish. As a finishing grade, it excels in continuous cuts and small depths of cut, where low tool pressure and minimal built-up edge are decisive. Cermet materials balance hardness and toughness: the cemented carbide substrate ensures wear resistance while the ceramic phase supports edge stability, making this insert well suited to parts requiring tight surface specifications and repeatable results.

Secure fit and ISO system compatibility

Compatibility in indexable tooling depends on shape, clearance angle, tolerance class, clamping method, size and thickness. This rhombic CCMT 09T308 geometry offers a standard 09 size with a 3.97 mm plate thickness and a 7° clearance that match common ISO holders. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for positive clamping and reliable repeatability. Because the fit is determined by these precise dimensions, the insert integrates readily into established tool systems, reducing set-up time and ensuring stable cutting conditions.

Practical cutting guidance and process benefits

A nose radius of 0.8 mm provides a balance between strength and fine edge definition, helping to achieve consistent part geometry and gloss. The one-sided chipbreaker is optimised for finishing chip control: it directs chips reliably during continuous turning, lowering the risk of surface damage. For best results, combine this insert with a rigid toolholder and moderate feed rates appropriate to finishing passes; heavy interrupted cuts or excessive depths of cut will reduce life and surface quality. The insert's properties lead to measurable process advantages such as reduced rework, predictable tool life and improved component aesthetics.

FAQ

What materials is this insert best suited for?
The CCMT09T308 NS9530 insert is optimised for finishing on steel; the uncoated cermet grade is designed to produce low cutting forces and high surface quality on continuous turning operations.

How is the insert secured in the toolholder?
This rhombic insert uses a cylindrical hole with a one-sided countersink (40°–60°) for positive clamping; compatibility depends on matching holder form, size and clamping system.

What cutting conditions suit this finishing grade?
Use small depths of cut and moderate feeds for finishing passes; the NS9530 grade performs best in continuous cuts where a sharp edge and stable cutting give the desired surface finish.

Can this insert be used for internal and external turning?
Yes, the geometry and chipbreaker make the insert suitable for both external and internal turning tasks, provided the toolholder and setup offer sufficient rigidity.

Which toolholder sizes accept this insert?
The insert conforms to ISO dimensions for CCMT 09 geometry; select holders rated for 09 inserts with matching clearance and clamping specifications to ensure correct fit and repeatability.
