TNMG220404 NS9530 – Turning insert, uncoated cermet, 0° clearance, Tungaloy

A TNMG220404 NS9530 indexable turning insert engineered for fine finishing of steel, offering a sharp cutting edge and a compact corner radius for low cutting forces and high surface quality

• Uncoated cermet grade NS9530
• Sharp cutting edge for fine finishing
• Corner radius 0.4 mm for high surface quality
• Double-sided chipbreaker for consistent chips

Precision finishing with low cutting forces

The insert is designed as an ISO-standard turning insert, optimised for finishing passes on steel where surface quality and dimensional consistency are critical. The uncoated cermet NS9530 provides a sharp, wear-resistant cutting edge that reduces built-up edge and requires lower cutting forces compared with conventional grades. The result is an improved surface finish and more stable tool behaviour during continuous cuts and small depths of cut. For machinists and production engineers this means fewer reworks and a predictable process window.

Secure clamping and straightforward compatibility

Being an ISO-design plate, compatibility with holders depends on form, clearance, tolerance class, fastening and plate thickness. The triangular format with a cylindrical hole allows reliable clamping in standard TNMG holders; the plate thickness of 4.76 mm and the included angle of 60° are compatible with matching ISO tooling systems. The secure clamping and double-sided chipbreaker ensure repeatable performance, making tool changeovers faster and minimising downtime in batch production.

Controlled chip formation and surface integrity

The double-sided chipbreaker is tailored for continuous cutting conditions and small feeds, producing controlled chip shapes that aid extraction and reduce tool interference. The compact corner radius of 0.4 mm balances edge strength with a fine surface finish, while the 0° clearance supports minimal rubbing and precise geometry reproduction. In practice, this means a stable cutting process and consistent part finish even on high-volume finishing operations.

Material and application clarity for process planning

Constructed on a cemented carbide substrate with an uncoated cermet cutting layer, the insert is specifically intended for finishing steel where sharpness and surface quality are prioritised. The chemistry and microstructure of the cermet grade reduce adhesion and maintain edge definition across typical finishing feeds. Process planners benefit from a predictable tool life and consistent results, especially when pairing the insert with rigid setups and optimised cutting parameters.

FAQ

Is this insert suitable for finishing steel?
Yes. The TNMG220404 NS9530 insert by Tungaloy is a finishing grade specifically designed for steel, offering a sharp cutting edge and low cutting forces for high surface quality.

Does the insert require a specific holder type?
Compatibility is governed by ISO form, clearance, tolerance class, fastening, size and thickness; the triangular TNMG format with a cylindrical hole fits standard TNMG holders when those parameters match.

What is the advantage of the NS9530 cermet grade?
The NS9530 uncoated cermet provides a sharp edge and good wear resistance for continuous finishing cuts, improving surface integrity and reducing the tendency for built-up edge.

Can the TNMG220404 be used for interrupted cuts?
The insert is optimised for continuous cutting and small depths of cut; for heavy interrupted cuts other grades or edge geometries may be preferable.

How does the corner radius affect the finish?
The 0.4 mm corner radius on the TNMG220404 balances edge strength with a fine surface finish, enabling consistent dimensional results on finishing passes.
