CNMG 090402 NS9530 Tungaloy indexable turning insert (ISO 090402)

The CNMG 090402 NS9530 is an ISO-format indexable turning insert designed for finishing steel; it provides a sharp cutting edge and low cutting forces for continuous turning operations.

• ISO-formatted CNMG 090402 insert
• Uncoated cermet NS9530 for finishing
• Sharp cutting edge for low cutting forces
• 0.2 mm nose radius, rhombic 80° geometry
• Double-sided chipbreaker, with cylindrical hole

Optimised finishing performance with minimal cutting forces

The combination of an uncoated cermet grade and a fine 0.2 mm nose radius makes this insert particularly well suited to finishing passes on steel where surface integrity and dimensional accuracy are critical. The NS9530 grade provides a sharp cutting edge that reduces cutting forces and the tendency for built-up edge during continuous cuts, which in turn lowers spindle load and improves feed stability. For production environments that prioritise surface quality and repeatability, this insert reduces downstream polishing or rework and supports stable cycle times.

ISO compatibility and secure clamping for reliable tool changeovers

Delivered in the ISO 090402 format, the insert fits standard holders when matching is made by form, clearance angle, tolerance class, fastening method, size and thickness. The rhombic 80° geometry and 0° clearance are common in turning holders, simplifying holder selection and inventory management. The central cylindrical hole ensures positive seating and repeatable clamping torque, while the double-sided chipbreaker permits indexation, doubling the available cutting edges per insert and reducing tool change frequency. This standardisation supports predictable set-up times and consistent part quality.

Material, grade and process benefits explained

Built on a carbide substrate with an uncoated cermet cutting material, this insert balances edge sharpness and wear resistance for finishing on steels. The design emphasises low cutting forces and excellent surface finish rather than heavy-duty roughing; it is therefore best selected for small depths of cut and continuous feed conditions. The double-sided configuration provides economical usage of the carbide body, while the precise geometry helps maintain stable chip formation and reduces the risk of vibration in light-turning operations. Using the correct chipbreaker and matching the grade to the workpiece material will extend insert life and secure repeatable results.

Practical application and productivity advantages

For external and internal turning, the insert excels in producing fine surface finishes and tight tolerances on steel components. When combined with a suitably rigid holder and correct clamping, the geometry minimises spring-in and promotes steady cutting. The predictable performance of the ISO-format insert reduces inspection failures and supports higher first-pass yields. Specifying this grade for finishing steps can lower cycle times by decreasing secondary operations and by enhancing tool-change planning through indexable use.

FAQ

What materials is this insert best suited for?
The CNMG 090402 NS9530 insert is formulated as a finishing grade for steel; the uncoated cermet composition delivers a sharp edge and low cutting forces ideal for continuous turning on steel.

How does the double-sided chipbreaker affect productivity?
Using the double-sided chipbreaker allows indexation of the insert, effectively doubling usable edges and reducing the frequency of insert replacements in production.

Is this insert compatible with standard ISO holders?
Yes; the ISO 090402 format, the rhombic 80° geometry and the 0° clearance support compatibility with standard turning holders when form, fastening and tolerance class match.

What cutting conditions are recommended for the NS9530 grade?
The NS9530 uncoated cermet is optimised for finishing passes with small depths of cut and continuous feeds to achieve high surface quality and reduced cutting forces.

Does the insert require a coated variant for abrasive materials?
For more abrasive or interrupted cutting conditions, a coated or differently graded insert should be considered; the listed insert is primarily tailored for fine finishing on steels.
