CNGG090304 NS9530 Turning Insert — Tungaloy (ISO CNGG 090304, finishing grade)

CNGG090304 NS9530 is a rhombic ISO turning insert designed for finishing operations on steel, offering a sharp cutting edge and a low cutting-force geometry.

• Finishing cermet grade NS9530
• 0.4 mm nose radius for fine surfaces
• 0° clearance angle for true finishing cuts
• Cylindric hole and double-sided economy

Precision finishing with reduced cutting forces

The NS9530 cermet grade delivers a consistently sharp edge that translates into lower cutting forces and superior surface finish during light, continuous cuts. As a finishing insert with a 0.4 mm nose radius and 0° clearance, it is optimised for minimal intrusion into the workpiece while delivering repeatable dimensional accuracy. The uncoated cermet substrate offers excellent edge integrity, which helps to maintain a high-quality finish on steel components with reduced burr formation and less need for secondary operations.

Consistent fit and secure clamping for reliable production

The ISO CNGG geometry and standardised dimensions ensure compatibility with ISO holders when form, clearance angle, tolerance class, fastening and thickness are matched. The plate’s cylindric hole and double-sided design support secure mounting and straightforward indexing, improving uptime and tool utilisation. With a plate thickness of 3.18 mm, the insert balances rigidity and access in confined toolholders, providing stable cutting behaviour even when modest feed rates are applied.

Practical effects on cycle time and part quality

Using an insert specified for finishing yields measurable benefits: better first-pass surface quality and fewer rework steps. For continuous-cut applications and small depths of cut the uncoated cermet chemistry in this insert helps to sustain a sharp edge over longer tool life windows, which can contribute to more predictable tool-change intervals. Select the matching chipbreaker and grade according to the material and machine stability to fully exploit the insert’s strengths in external and internal turning operations; the product is especially suitable where a high-quality surface is the primary objective.

FAQ

What cutting applications is this insert best for?
This insert is optimised for finishing cuts in turning; the NS9530 grade and 0.4 mm nose radius are selected for continuous cuts and small depths of cut on steel.

Can the insert be used for internal turning as well as external turning?
Yes, the rhombic CNGG090304 geometry and slim 3.18 mm thickness allow use in both external and internal turning when the appropriate holder is chosen.

How does the uncoated cermet grade affect performance?
The NS9530 uncoated cermet provides a sharp edge and stable cutting behaviour for high-quality surfaces; it reduces cutting forces in finishing scenarios compared with some coated alternatives.

Is the insert indexable and economical to use?
The insert is double-sided and indexable, offering two usable cutting edges per side and supporting efficient tool cost management in production.

Which holder features must be matched for correct compatibility?
Compatibility depends on matching the insert form, 0° clearance angle, tolerance class, fastening method, size and thickness with the chosen ISO holder.
