DNMG 110408 NS9530 Tungaloy Turning Insert — ISO-indexable finishing insert for turning

DNMG110408 NS9530 Tungaloy is an ISO-indexable turning insert optimised for fine finishing of steel components in continuous external and internal turning operations

• ISO-indexable DNMG form, rhombic geometry
• Cermet grade NS9530 for fine finishing
• Sharp cutting edge for low cutting forces
• Double-sided insert, 0° clearance

Achieve consistent high-quality finishes with a low-force cutting grade

The uncoated cermet grade NS9530 was developed for finishing applications where surface integrity and dimensional consistency are decisive. The sharp edge geometry reduces friction and produces low cutting forces, which leads to smaller form deviations and minimises chatter on less rigid setups. For continuous cuts and small depths of cut, this characteristic shortens cycle times by reducing the need for secondary operations while improving the first-pass finish.

Fast fit-up and secure clamping for reliable production

Manufactured to ISO dimensions and tolerances, the rhombic DNMG shape with a cylindrical hole ensures predictable compatibility with standard external holders and boring bars. The insert is double-sided, allowing economical index changes, and the plate thickness 4.76 mm together with the 0° clearance create a stable seat in the pocket. The corner radius 0.8 mm gives a balance between edge strength and fine surface generation, supporting shorter set-up times and dependable repeatability across production batches.

Broad applicability in turning with a focus on productivity

Designed primarily for turning applications, the grade is particularly suited to finishing of steels where continuous cutting and modest chip loads prevail. The combination of cermet chemistry and a sharp cutting edge promotes excellent surface finish while maintaining reasonable tool life in steady-state conditions. Selecting the appropriate chipbreaker and matching the grade to the workpiece stability and feed conditions will optimise cutting performance and throughput.

FAQ

What cutting applications suit this insert best?
The DNMG 110408 NS9530 Tungaloy turning insert is intended for finishing operations on steel, especially continuous external and internal turning where a fine surface finish and low cutting forces are required.

Is the insert compatible with standard DNMG holders?
Yes. The insert conforms to ISO DNMG dimensions; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness — standard DNMG holders will accept this designation.

How does the NS9530 grade affect tool life and finish?
NS9530 is an uncoated cermet grade optimised for high surface finish and low cutting forces; it typically delivers excellent finish quality in continuous finishing cuts while providing reasonable wear resistance under stable conditions.

Can the insert be indexed to use a second cutting edge?
Yes. The double-sided design allows rotation to a fresh edge, extending the usable life of each insert and improving cost-efficiency for batch production.

What is the recommended corner radius for fine finishing?
The 0.8 mm corner radius on this insert is a compromise between edge strength and the ability to generate a fine surface; it is well suited to finishing passes with modest feed rates.
