CNMG 090408 NS9530 Tungaloy turning insert — ISO finishing insert, 80° rhombic, uncoated cermet

A CNMG 090408 NS9530 Tungaloy turning insert designed for finishing steel with low cutting forces and excellent surface results

• Uncoated NS9530 cermet finishing grade
• 80° rhombic geometry CNMG insert
• Double-sided chipbreaker design
• Cylindrical hole for secure clamping

Consistent finishing performance for steel components

The CNMG geometry combined with the NS9530 uncoated cermet provides a sharp cutting edge that reduces friction and enables a high surface finish on steel. This grade is optimised for continuous cuts and small depths of cut, so the result is a fine, consistent surface without excessive vibration. The low cutting forces associated with the cermet grade also reduce tool loading and help maintain machine stability during finishing passes, which translates directly into fewer reworks and predictable process outcomes.

Secure clamping and ISO compatibility for easy integration

The insert follows ISO dimensions and the rhombic CNMG090408 form, ensuring compatibility with a wide range of standard turning holders. The cylindrical hole and the plate’s 4.76 mm thickness allow reliable mechanical clamping and straightforward indexing. Compatibility is determined by holder form, clearance angle, tolerance class, fastening method, size and thickness; using the correct matching holder keeps the cutting geometry stable and streamlines tool changes on the shopfloor.

Operational advantages and handling notes

A 0.8 mm nose radius and the double-sided chipbreaker design make this grade particularly suited to finishing operations where surface integrity matters. The combination of cermet edge quality and CNMG geometry reduces burr formation and heat transfer into the workpiece, which benefits dimensional stability. Handling is simple: index the insert as per the holder’s instructions and monitor cutting parameters for continuous-cut conditions to achieve the intended performance and surface quality.

FAQ

Which materials is this insert intended for?
The CNMG 090408 NS9530 Tungaloy insert is a finishing grade developed primarily for steel applications; the uncoated cermet composition yields low cutting forces and an excellent surface finish when used in continuous-cut conditions.

What does the CNMG geometry mean for surface quality?
The 80° rhombic CNMG geometry with a 0.8 mm nose radius provides a stable cutting edge and reduced edge loading, which together improve surface integrity and make the insert well suited to fine finishing passes.

Is the insert indexable and reversible?
Yes — the insert is double-sided with a chipbreaker on both cutting edges and features a cylindrical hole for secure clamping, permitting indexing to the second cutting edge for extended usage.

Which holders are compatible with this insert?
Compatibility requires an ISO CNMG holder matching the insert’s form, clearance angle, tolerance class, fastening and thickness; using the correct holder ensures the expected performance from the CNMG 090408 NS9530 Tungaloy insert (SKU TUN6966089).

For which cutting conditions is this grade recommended?
The NS9530 finishing grade is recommended for continuous cutting and small depths of cut where a fine surface finish and low cutting forces are priorities.
