TNMG220408 NS9530 ISO turning insert — uncoated cermet, finishing for steel (Tungaloy)

The TNMG220408 NS9530 is an ISO-standard turning insert engineered for finishing operations on steel, delivering a sharp cutting edge, low cutting forces and excellent surface quality.

• Uncoated cermet finishing grade
• Sharp cutting edge for superior finish
• 60° triangle form, 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Precision finishing for demanding steel applications

The uncoated cermet grade is formulated specifically as a finishing variant for steel, providing a sharp cutting edge and reduced cutting forces. This combination results in improved surface integrity and tighter tolerances on the final component. In practical terms, the composition minimises built-up edge during continuous cuts, so a smooth matte or mirror-like surface can be achieved with small depths of cut. For manufacturers seeking consistent part appearance and reduced rework, the finishing grade translates directly into time savings at downstream processes.

Reliable fit and secure clamping within ISO tool systems

This insert conforms to ISO plate geometry and is compatible with standard holders when matched by form, clearance angle, tolerance class, fastening method, size and thickness. The presence of a cylindrical hole supports secure clamping and simplified indexing, while the triangular plate form allows economical rotation to fresh cutting edges. Using the correct holder, shim and clamp combination as part of the system assembly ensures stable contact, accurate repeatability and safe cutting conditions during external and internal turning.

Geometry engineered for stable cuts and surface consistency

The 60° triangular form combined with a 0.8 mm corner radius balances cutting-edge strength with the ability to produce fine surface finishes. A modest corner radius reduces radial forces and vibration during light finishing passes, while the double-sided chipbreaker assists chip control and shearing behaviour at low cross-sections. For operations where small feed rates and continuous cutting dominate, this geometry supports consistent dimensional results and predictable tool performance.

Application guidance for maximum productivity

Designed for turning applications where surface quality is the priority, the plate is well suited to continuous cuts and small material removals. Selecting the appropriate chipbreaker and grade according to workpiece material, machining stability and depth of cut is essential; the NS9530 finishing variety is matched to steel and performs best with controlled feeds for topographical surface finish. Integrating this insert into a coherent tooling system promotes longer effective tool life and steady component throughput in finishing cycles.

FAQ

What materials is this insert intended for? The NS9530 finishing grade is intended primarily for steel; the TNMG220408 NS9530 insert is optimised for continuous cuts on steel workpieces.

How does the 0.8 mm corner radius affect results? A 0.8 mm corner radius reduces radial loads and vibration during finishing passes, producing more consistent surface quality and improved dimensional stability when using moderate feeds.

Is the insert compatible with standard ISO holders? Compatibility is achieved when holder form, clearance angle, tolerance class, fastening, size and thickness match the ISO insert; the TNMG220408 fits ISO-standard triangular holder designs with cylindrical-hole clamping.

What benefit does the uncoated cermet offer over coated grades? Uncoated cermet provides a very sharp cutting edge and lower cutting forces for superior finishes in continuous cutting; NS9530 focuses on surface quality rather than high-feed roughing.

Can this insert be used for internal turning? Yes, the geometry and chip control make the insert suitable for both external and internal turning when combined with an appropriate boring bar or holder.

How is chip control handled with this insert? The double-sided chipbreaker is designed to promote controlled chip formation during finishing cuts, aiding evacuation and preventing interference with the finished surface.
