CNMG 120408 NS9530 Tungaloy indexable turning insert for finishing operations

The CNMG120408 NS9530 indexable turning insert is designed for finishing steel operations, combining a sharp cutting edge with low cutting forces for improved surface quality and consistent results.

• Cermet grade NS9530 for fine surface finish
• Sharp cutting edge for low cutting forces
• Double-sided chipbreaker for continuous cuts
• ISO CNMG 120408 form with cylindrical hole

Consistent fine surface finish from a cermet finishing grade

The uncoated cermet grade NS9530 is formulated for finishing applications on steel, offering a sharp cutting edge that reduces cutting forces and minimises built-up edge. In practice, this yields a finer surface texture and reduces secondary finishing requirements. The combination of the sharp edge and the low-vibration cutting behaviour of the plate is especially beneficial when machining continuous cuts or taking small depths of cut, where surface integrity and dimensional stability are critical.

Reliable process with ISO-compliant geometry and secure clamping

The rhombic CNMG form in the ISO CNMG120408 format provides a well-established geometry for both external and internal turning. The plate’s 80° cutting angle and 0° relief support predictable tool engagement, while the cylindrical hole allows secure locating and repeatable clamping in standard CNMG holders. As a double-sided insert, it delivers economical use of the cutting edges and smooth indexability, supporting stable production runs and quick tool changeovers.

Chip control and system integration for productive turning

A double-sided chipbreaker matched to the uncoated cermet improves chip formation during continuous cutting, lowering the risk of recutting and easing swarf handling. The insert’s 0.8 mm corner radius contributes to robustness in finishing passes without compromising surface appearance. Integration into a complete tool system — ISO insert, compatible external holder or boring bar, support shim and clamping set — ensures correct seating and simple spare part management, supporting high machine uptime and predictable component quality.

FAQ

Is this insert suitable for finishing steel? Yes. The CNMG120408 in NS9530 is a finishing-grade, uncoated cermet insert specifically intended for steel finishing, delivering a sharp cutting edge and reduced cutting forces.

Can the plate be indexed to use all cutting edges? Yes. The CNMG form is double-sided and indexable; the design allows rotation to the next edge for economical edge usage and extended tool life.

Which tool holders are compatible with this ISO plate? Compatibility is determined by ISO CNMG form, hole style and thickness; the CNMG120408 fits standard CNMG holders and rails when the holder matches form, relief and tolerance class.

What chip control can be expected with this grade? The double-sided chipbreaker has been chosen for continuous cuts and produces controlled chip formation in finishing conditions, improving process stability.

Is the insert supplied with mounting hardware? The product is the indexable insert itself; holders, shims and clamping sets are part of the overall tool system and should be sourced separately to match CNMG120408 specifications.
