TNMG160408 NS9530 — TNMG turning insert, finishing grade, by Tungaloy

A TNMG160408 NS9530 triangular finishing insert designed for precision external and internal turning of Stahl with a sharp cutting edge and low cutting forces

• Finishing cermet NS9530 for exceptional surface finish
• Sharp cutting edge for low cutting forces
• ISO triangular insert, 60° included angle
• Double-sided chipbreaker with cylindrical hole

Achieve finer surfaces with a dedicated finishing grade

The uncoated cermet grade NS9530 is developed for finishing of Stahl, offering a sharp cutting edge and low cutting forces that reduce rubbing and heat generation. For continuous cutting and small depths of cut the result is a consistently high surface finish, decreased need for grinding and fewer secondary operations. The triangular geometry and 0.8 mm corner radius support stable contact conditions while the 60° included angle provides reliable seating in ISO-compatible toolholders.

Consistent process stability and longer effective life

A double-sided chipbreaker and the insert’s precise dimensions make changeover predictable and minimises downtime. The insert’s 4.76 mm thickness and standard ISO form ensure compatibility with a wide range of external holders and boring bars when the holder is matched for form, relief angle, tolerance class, fastening and size. Together these factors promote process stability, repeatable part quality and efficient batch production with reduced scrap rates.

Practical selection guidance for workshop use

Choose the chipbreaker and NS9530 grade according to workpiece Stahl grade, machine rigidity and cutting parameters; the insert excels in finishing passes where surface quality is critical. The presence of a cylindrical hole facilitates secure clamping and rapid indexation. For many applications a small radial depth and finishing feed deliver the expected performance; when in doubt, request detailed cutting data or trial cuts to align insert geometry with setup stiffness and spindle speed.

FAQ

What is the primary application of this insert?
The TNMG160408 NS9530 Tungaloy turning insert is intended for finishing operations on Stahl, suitable for both external and internal turning where a fine surface finish and low cutting forces are required.

How should cutting parameters be adapted for the NS9530 grade?
Use modest depths of cut and finishing feeds for the NS9530 cermet grade; the material excels in continuous cutting and small allowances, which helps to achieve the best surface quality and tool life.

Is the insert compatible with standard ISO holders?
Yes — the ISO designation and the TNMG form make the insert compatible with ISO toolholders when the holder matches the insert’s form, relief angle, tolerance class, fastening method, size and thickness.

What advantage does the double-sided chipbreaker provide?
The double-sided chipbreaker allows two indexing positions, increases usable edge life and supports predictable chip control during finishing passes, which contributes to consistent component quality.

Which workpiece materials suit this insert best?
This uncoated cermet grade is optimised for finishing of Stahl; selection of a different chipbreaker or grade is advised for other materials or heavy roughing operations.
