• Uncoated cermet with sharp cutting edge
• Optimised for continuous turning at low feeds
• ISO-compatible with 35° lead angle

High-precision finishing with a low cutting-force grade

The insert is offered in the NS9530 uncoated cermet grade, a finishing specification developed to deliver a sharp cutting edge and low cutting forces when machining steel. This results in consistently improved surface integrity and fewer secondary operations. As an ISO 160404 rhombic insert with a 0.4 mm nose radius, it is particularly suitable for small-depth finishing passes where dimensional accuracy and surface quality are decisive. The combination of a fine, wear-resistant cermet and a geometrically stable edge reduces the tendency for edge build-up in continuous cuts and supports longer intervals between tool changes.

Secure clamping and form-fit compatibility for predictable results

Compatibility with the toolholder is determined by form, clearance angle, tolerance class, fixing method, size and thickness; the insert features a cylindrical hole with a single-sided countersink (40°–60°) to ensure reliable seating and repeatable positioning. The 35° lead angle and 5° clearance angle provide an advantageous geometry for external and internal turning, allowing stable chip flow and consistent contact with the workpiece. This predictable clamping behaviour supports process stability and makes tool-set selection straightforward when integrating the insert into existing ISO tooling systems.

Practical advantages for continuous turning and finishing cycles

Designed as a finishing grade, the cutting geometry and material pairing reduce vibration and deliver better surface finishes on steel, especially during continuous-feed operations with modest depths of cut. The TM chipbreaker geometry promotes controlled chip formation for steady evacuation, lowering the likelihood of re-cutting and surface blemishes. For shops seeking to upscale batch quality without complex parameter changes, the insert’s characteristics translate into fewer rejects and less downstream polishing, improving overall throughput.

Handling, selection and lifecycle considerations

The insert’s 4.76 mm thickness and rhombic form support straightforward indexing and economical stock management. When establishing cutting data, prefer conservative feed rates and exploit the low-force behaviour of the cermet grade to achieve the target finish; the fine 0.4 mm radius helps maintain dimensional accuracy on radiused profiles. Although uncoated, the grade’s toughness and edge stability provide respectable wear resistance in finishing roles; this often permits longer productive life in continuous, low-variation operations compared with standard finishing inserts.

FAQ

What materials is this grade intended for?
The NS9530 uncoated cermet grade is formulated primarily for finishing operations on steel, offering low cutting forces and a sharp edge suitable for continuous turning.

Which ISO designation and insert form does this item use?
This product follows the ISO 160404 designation in a rhombic VBMT form; the geometry and size align with standard ISO holders for straightforward replacement.

How does the TM chipbreaker influence machining?
The TM chipbreaker promotes controlled chip formation and evacuation during continuous cuts, supporting consistent surface finish and reduced risk of re-cutting.

Is the insert compatible with standard clamping systems?
Yes; the insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) for secure and repeatable seating in ISO-compatible clamping systems.

What are the key geometric specifications to note when programming?
Key values are a 35° lead angle, 5° clearance angle, 4.76 mm thickness and a 0.4 mm nose radius; these parameters help set conservative feeds and depths for finishing passes.
