CPMT 090302 NS9530 — Tungaloy turning indexable insert, uncoated cermet for fine finishing

The CPMT090302 NS9530 is a rhombic ISO turning insert designed for finishing operations on steel, optimised for continuous cuts and small depths of cut.

• Sharp cutting edge for superior surface finish
• Uncoated cermet grade NS9530 for fine finishing
• ISO rhombic 09 shape with 80° cutting angle
• Compatible with ISO turning holders

Precision finishing with low cutting forces

The insert combines an uncoated cermet grade with a sharp cutting edge, delivering low cutting forces and excellent surface quality on steel. Cermet is a ceramic–metal composite that maintains edge sharpness longer than many carbides in finishing passes; this reduces vibration and improves part tolerances. For continuous feeding and small step-over values the result is a measurable improvement in surface roughness and reduced need for secondary operations, making it a cost-effective choice for high-volume finishing.

Clear mounting parameters for reliable toolholding

Compatibility with toolholders follows ISO principles: form, free angle, tolerance class, fastening, size and thickness determine fit. The insert’s 11° relief angle and 80° cutting angle are specified to match standard ISO holders for rhombic plates, while the cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping and repeatable seating. Specifying these parameters avoids misfits and supports fast indexable changeovers, reducing machine downtime and increasing process security.

Application guidance and operational benefits

Designed for external and internal turning, this grade is particularly suited to continuous cuts and finishing passes on steel where surface integrity matters. The 0.2 mm corner radius balances edge strength with fine profile reproduction, and the 3.18 mm plate thickness contributes to operational stability under light to moderate cutting forces. The integrated single-sided chipbreaker assists chip control in predictable cutting regimes, reducing the risk of built-up edge and supporting consistent cycle times.

FAQ

Which materials is this insert intended for?
The CPMT090302 NS9530 is formulated as a finishing grade for steel, offering low cutting forces and a sharp edge suitable for high-quality surface results.

Can the insert be used for internal turning operations?
Yes, the rhombic geometry and secure hole clamping make the insert suitable for both external and internal turning when matched with the correct ISO holder.

Is the grade coated or uncoated, and what are the benefits?
This Tungaloy grade is an uncoated cermet; the advantage is a consistently sharp edge and improved surface finish in finishing applications where coating-related edge build-up is a concern.

How should the toolholder be selected for reliable performance?
Select a holder that matches the ISO form, 11° relief angle, tolerance class, fastening method, size and thickness; correct matching ensures repeatable seating and clamping stability.

What role does the 0.2 mm corner radius play in finishing?
A 0.2 mm radius provides a balance between edge strength and fine profile reproduction, improving surface integrity while limiting tool deflection in light finishing cuts.
