CCMT 09T304 NS9530 Tungaloy turning insert — ISO CCMT finishing grade for turning

A CCMT09T304 NS9530 ISO turning insert engineered for finishing steel with a sharp cutting edge, low cutting forces and excellent surface quality.

• Uncoated cermet NS9530 for superior surface finish
• 0.4 mm corner radius for precise machining
• ISO rhombic CCMT form with 7° clearance angle
• Cylindrical hole with 40°–60° countersink for fastening

Precision finishing where surface quality matters

The combination of uncoated cermet NS9530 and the ISO CCMT geometry delivers a finishing solution optimised for steels that require a sharp cutting edge and low cutting forces. The fine grade is designed for continuous cuts and small depths of cut, enabling a consistent high surface finish while limiting tool-induced vibration. In practical terms, users can expect improved first-pass results in external and internal turning operations where finish and dimensional accuracy are priorities.

Reliable fit and secure clamping for consistent performance

Compatibility of the insert with the toolholder is determined by geometry, tolerance class, fastener style, size and thickness. The rhombic plate form, 7° clearance angle and cylindrical hole with single-sided countersink (40°–60°) ensure repeatable seating and straightforward clamping. The plate thickness of 3.97 mm and size 09 conform to ISO specifications, making replacement and inventory management straightforward for ISO-compliant tool systems.

Operational benefits in routine turning tasks

A 0.4 mm corner radius provides a balance between edge strength and the ability to achieve fine surface finishes on steel components. The single-sided chipbreaker supports controlled chip formation in finishing cuts, reducing the risk of surface defects and secondary operations. The reduced cutting forces associated with this grade also help to minimise induced chatter on smaller overhangs, contributing to more efficient cycle times and lower scrap rates in stable machining setups.

Practical selection and system considerations

Choose a matching chipbreaker and holder according to workpiece material, machining stability and depth of cut; the single-sided chipbreaker suits finishing passes on steel. The typical system comprises the ISO turning insert, a compatible external holder or boring bar, a backing/clamping set and replacement screws. For bespoke applications or uncertainty on holder compatibility, guidance is available to ensure the insert and tooling system are optimised for the desired finish and productivity.

FAQ

What materials is this insert suitable for?
The insert is specified as a finishing grade for steel; the NS9530 uncoated cermet is optimised for producing high surface quality in continuous cutting conditions.

Which ISO designation and size does it use?
This cutting insert is ISO designated CCMT09T304 (size 09) and follows the ISO rhombic CCMT form factor for compatibility with standard holders.

What fastening style is required for the insert?
The plate features a cylindrical hole with a single-sided countersink (40°–60°) and is clamped in holders designed for CCMT plates with matching hole and tolerance classes.

Is the insert appropriate for internal as well as external turning?
Yes; the geometry and grade are suitable for both external and internal finishing passes when paired with the correct boring bar or holder and appropriate machining parameters.

How does the NS9530 grade affect cutting behaviour?
The NS9530 cermet grade provides a sharp cutting edge, low cutting forces and strong surface finish performance, particularly advantageous for finishing cuts and small depths of cut.
