CNMG 120402 NS9530 — Turning insert (finishing) by Tungaloy

A CNMG120402 NS9530 indexable insert engineered for precision external and internal turning of steel in finishing applications

• Finishing grade NS9530, uncoated cermet
• Sharp cutting edge for low cutting forces
• Rhombic CNMG shape, 80° cutting geometry
• 0.2 mm corner radius, double-sided chipbreaker

High-precision finishing for steel components

The CNMG120402 NS9530 insert is a finishing-grade solution tailored to deliver excellent surface finish on steel components through a combination of a sharp cutting edge and low cutting forces. The uncoated cermet composition provides a chemically stable, hard cutting edge that maintains geometry during continuous cuts and small depths of cut, making it particularly suitable for operations where surface integrity and dimensional accuracy are priorities. By reducing cutting forces, the insert helps lower vibration, which in turn supports consistent part quality and extended tool life.

Geometry and material deliver measurable process benefits

Engineered as a rhombic CNMG, the insert features an 80° included angle, a 0° clearance, a 0.2 mm corner radius and a plate thickness of 4.76 mm, all of which contribute to predictable cutting behaviour and mounting stability. The double-sided chipbreaker supports two usable faces per side, improving cost efficiency and offering repeatable chip control when matched to appropriate machining conditions. The base material—carbide substrate with a cermet cutting surface—combines wear resistance with edge sharpness to produce fine surface textures on steels without reliance on a coating.

System compatibility and practical selection guidance

This insert conforms to the ISO series of turning inserts and forms part of a system comprising a matching external holder or boring bar, underlay/clamping set and fastening screws; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness. The double-sided, rhombic design and cylindrical hole require a compatible clamping seat and screw arrangement. For best results, select the chipbreaker and grade according to the specific steel alloy, the intended cut (continuous vs interrupted) and machine-tool stability. The combination of the NS9530 grade and the rhombic CNMG geometry is engineered to enhance process reliability while delivering efficient finishing performance in shop-floor turning applications.

FAQ

What materials is this insert intended for?
The CNMG120402 NS9530 insert is a finishing-grade cermet designed primarily for machining steel, offering low cutting forces and a fine surface finish when used in continuous turning operations.

How does the NS9530 grade affect performance?
The NS9530 uncoated cermet provides a very sharp cutting edge with good wear resistance for finishing; the Tungaloy NS9530 grade is optimised to reduce cutting forces and improve surface integrity under stable conditions.

Is the insert compatible with standard CNMG holders?
Compatibility is determined by holder form, clearance angle, tolerance class, fastening method, size and plate thickness; the CNMG120402 shape follows ISO dimensions and requires a holder matching those parameters.

Can the insert be used for interrupted cuts?
The insert is optimised for continuous cuts and small depths of cut; for interrupted machining, choose a chipbreaker and grade selected for the specific material and stability requirements rather than relying solely on this finishing grade.

How many cutting edges are available per insert?
The double-sided chipbreaker design provides multiple usable edges; specific edge counts depend on the insert orientation and indexability on the chosen holder.
