TNMG 220408 NS9530 – Turning insert (uncoated Cermet) by Tungaloy

TNMG220408 NS9530 is a triangular ISO turning insert designed for finishing operations on steel, offering a sharp cutting edge and stable chip control for continuous cuts.

• Finishing uncoated Cermet grade NS9530
• Low cutting forces for continuous cuts
• Double-sided chipbreaker for consistent chips
• ISO TNMG 220408 with 0.8 mm corner radius

Improved surface finish with low cutting forces

The TNMG geometry with its sharp uncoated Cermet edge is engineered for finishing passes where surface quality is critical. The combination of the fine-grain Cermet grade NS9530 and the small 0.8 mm corner radius reduces vibration and minimises burr formation, resulting in a consistently higher surface finish on steel components. For shops aiming to reduce secondary operations, the measurable benefit is shorter downstream processing time and more parts meeting tolerance on first pass.

Compatibility and reliable chip control for stable processes

As an ISO-standard indexable insert, compatibility with holders is determined by form, relief angle, tolerance class, fastening, size and thickness, ensuring predictable assembly into established tool systems. The double-sided chipbreaker and triangular plate form with a cylindrical hole promote dependable chip formation during continuous turning, lowering the risk of built-up edge and enabling steady cutting conditions. This stability supports higher machine utilisation and fewer interruptions on the production floor.

Practical productivity advantages and material suitability

The uncoated cermet composition is optimised for finishing steel, offering low cutting forces and excellent edge wear resistance in continuous-cut scenarios. The insert’s 0° clearance angle and 60° included angle suit fine finishing, while the ISO sizing simplifies inventory management across multiple machines. Choosing this insert can shorten cycle times and improve repeatability, delivering a clear return through reduced rework and consistent part quality.

FAQ

What workpiece materials is this insert suited to?
The TNMG220408 NS9530 turning insert is specified as a finishing grade for steel, with the uncoated Cermet composition delivering low cutting forces and excellent surface quality in continuous cuts.

Is the insert compatible with standard TNMG toolholders?
Yes, the insert uses the ISO designation 220408 and fits holders that match form, relief angle, tolerance class, fastening and thickness for TNMG inserts; confirm holder compatibility before fitting.

How does the chipbreaker affect machining?
The double-sided chipbreaker on this insert supports consistent chip formation during finishing operations, improving process stability and reducing the chance of built-up edge under continuous cutting conditions.

Can the insert be indexed or reversed?
The triangular plate form with a cylindrical hole and double-sided geometry allows indexing to fresh edges, extending useful tool life while maintaining repeatable cutting performance.

What measurable benefits can be expected when switching to this grade?
When applied for finishing steel, the NS9530 uncoated cermet grade typically reduces cutting forces and improves surface finish, which can decrease downstream finishing and increase first-pass yield for many turning operations.
