CPGT 090302 NS9530 – Turning insert for finishing operations, Tungaloy

The CPGT090302 NS9530 is an ISO‑form rhombic turning insert designed for finishing on steel, delivering low cutting forces and superior surface quality in continuous cuts.

• Finishing uncoated cermet grade NS9530
• Sharp cutting edge for low cutting forces
• ISO rhombic insert 09, 3.18 mm thick
• Single-sided chipbreaker for continuous cuts

Consistent finishing quality through a sharp uncoated cermet grade

The uncoated cermet grade NS9530 is formulated for finishing cuts on steel where a sharp cutting edge and low cutting forces are decisive. The material composition promotes a fine edge and reduced built‑up edge, which together produce a consistently high surface finish even with small depths of cut. For operations that demand repeatable part quality, this finishing grade reduces the need for secondary processes and supports steady throughput with fewer interruptions.

Precise fit and geometry for secure clamping and stable cutting

ISO compliance ensures the insert fits holders that match the rhombic form and the defined tolerances; compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The CPGT090302 features an rhombic 09 form with a corner radius of 0.2 mm, a clearance angle of 11° and a plate thickness of 3.18 mm, ensuring predictable engagement and stiffness in the cut. The insert’s hole—cylindrical with a one‑sided countersink—permits reliable clamping, while the single‑sided chipbreaker promotes controlled chip formation during continuous cutting, improving process stability and tool life. Choosing the correct holder and clamping set accordingly minimises vibration and maximises dimensional accuracy.

Practical application guidance and system considerations for turning

This ISO turning insert is intended for external and internal turning in finishing applications on steel where small feed and depth parameters are used. The combination of a sharp cermet edge and single‑sided chip control makes it especially suited to continuous cuts and precision finishing passes. The typical system comprises the ISO insert, a compatible external holder or boring bar, a shim/clamping set and replacement screws; ensuring all components meet the specified form and tolerance class is essential for safe, repeatable results. For users new to cermet grades, note that these inserts favour stable cutting conditions and benefit from optimised coolant strategies and consistent feed to maintain surface integrity.

FAQ

What materials is this insert designed for?
The insert is supplied in the uncoated NS9530 cermet grade and is intended primarily for finishing operations on steel.

Which holder features are required for secure use?
Compatibility depends on holder form, clearance angle, tolerance class, fastening, size and thickness; the insert’s cylindrical hole with countersink requires a matching clamp and screw arrangement.

Is this insert suitable for internal and external turning?
Yes, the ISO rhombic form and chip control make it suitable for both external and internal finishing passes under stable cutting conditions.

How does the single-sided chipbreaker affect machining?
The single‑sided chipbreaker is designed to control chip formation during continuous cuts, reducing the risk of entanglement and improving process reliability.

Can this insert be used for interrupted cuts?
The NS9530 finishing grade is optimised for continuous cutting and small depths of cut; interrupted cuts may reduce tool life and surface quality compared with stable continuous conditions.
