CNMG120404 NS9530 CNMG Turning Insert — Tungaloy — Uncoated cermet, 0.4 mm radius

A CNMG120404 NS9530 turning insert designed for finishing operations on steel, offering a sharp cutting edge, low cutting forces and ISO‑compatible rhombic geometry for reliable external and internal turning.

• ISO‑standard rhombic insert, 80° approach angle
• Uncoated cermet NS9530 for fine finishing
• 0.4 mm corner radius for precise edge control

Achieve consistently high surface quality with a finishing grade insert

The uncoated NS9530 cermet grade is formulated for finishing steel where a sharp cutting edge and low cutting forces are decisive. Cermet combines ceramic hardness with metal toughness, which reduces flank wear during continuous cuts and supports a stable process when small depths of cut are specified. This results in a finer surface finish and reduced need for rework, making the insert particularly suitable for components requiring tight dimensional and aesthetic standards.

Simple mounting and ISO interchangeability cut setup time

The insert follows the ISO rhombic designation and is produced to the CNMG120404 contour, so compatibility is determined by form, clearance angle, tolerance class, fixation method, size and thickness. The geometry features an 80° approach angle, a 0° clearance angle and a cylindrical central hole, enabling secure clamping in standard CNMG holders or on a compatible boring bar. The system is intended to be used with a matching external holder, shim/clamping set and replacement screws, which are specified separately for a complete toolset.

Productivity gains from controlled chip formation and tool life

A double‑sided chipbreaker and the fine 0.4 mm corner radius support controlled chip formation and stable cutting forces during finishing passes. The combination of grade and geometry reduces the likelihood of edge chipping under continuous cutting conditions and helps to maintain repeatable dimensional accuracy across batches. For workshops aiming to increase throughput without compromising finish, this turning grade provides an economical balance of performance and handling simplicity.

FAQ

What materials is this insert intended for?
The NS9530 grade is a finishing cermet developed for machining steel; it delivers a sharp edge and low cutting forces suited to continuous finishing cuts.

Is the CNMG120404 insert double‑sided and reversible?
Yes, the CNMG120404 geometry is double‑sided with a double‑sided chipbreaker, allowing the indexation of a fresh cutting edge when required.

Which holder types are compatible with this insert?
Compatibility is based on ISO form, clearance angle and size; the CNMG120404 insert is intended for standard CNMG holders or compatible boring bars designed for rhombic inserts.

Does the insert require a specific clamping set or screws?
A matching shim/clamping set and replacement screws form part of the overall system and should be selected to match the insert’s cylindrical hole and tolerance class.

How does the 0.4 mm corner radius affect the machining result?
A 0.4 mm radius provides controlled edge strength for finishing operations, improving surface quality while keeping radial cutting forces moderate.
