DCMT070208 NS9530 – ISO indexable turning insert, uncoated cermet, 0.8 mm radius (Tungaloy)

The DCMT070208 NS9530 is an ISO rhombic indexable turning insert engineered for precision finishing in conventional turning operations.

• Uncoated cermet for superior surface finish
• 0.8 mm corner radius for fine contouring
• 7° clearance angle for reduced cutting forces
• Cylindrical hole with single-sided countersink

High-precision finishing with low cutting forces

The insert is manufactured as a finishing grade, featuring an uncoated cermet composition optimised for low cutting forces and a consistently sharp cutting edge. This configuration produces an outstanding surface finish on steel during continuous cuts and fine feed applications. The modest corner radius combined with the sharp edge results in reduced radial forces and less vibration, which supports dimensional stability and longer effective tool life in precision turning operations.

ISO compatibility and system considerations for secure clamping

Designed as an ISO-standard indexable insert, compatibility with the toolholder depends on several mechanical factors: form, clearance angle, tolerance class, mounting method, size and thickness. The rhombic 07 format and a cylindrical centre hole with a single-sided countersink (40°–60°) enable secure seating and repeatable indexing in common external holders and boring bars. Choosing the correct holder geometry and clamping set ensures reliable seat contact and consistent cutting performance across production runs.

Application focus and operational benefits for turning steel

This grade is tailored for turning where fine surface quality and sharp edges are required; the 0.8 mm corner radius is particularly suited to small depths of cut and finishing passes. The single-sided chipbreaker supports controlled chip formation for stable cutting when machining steels, while the ISO geometry facilitates quick replacement and indexation. In practice, the insert delivers predictable results in series production and single-part work where consistent surface integrity and process stability matter.

FAQ

What materials is this insert intended for?
The DCMT070208 NS9530 insert is specified as a finishing grade for steel; the NS9530 uncoated cermet delivers low cutting forces and a high surface quality when used for turning steel.

How does the 0.8 mm corner radius affect machining results?
A 0.8 mm corner radius gives finer contour definition and reduced vibration during finishing cuts, helping to achieve consistent dimensional accuracy with the Tungaloy indexable turning insert.

Is this insert compatible with my ISO toolholder?
Compatibility depends on holder form, clearance, tolerance class, mounting method, size and thickness; the DCMT070208 follows ISO geometry and fits holders designed for rhombic 07 inserts with the corresponding clamping system.

What is the purpose of the centre hole and countersink?
The central cylindrical hole with single-sided countersink (40°–60°) secures the insert with standard clamping screws, ensuring repeatable seating and safe indexing in turning holders.

Can the insert be used for interrupted cuts or roughing?
This uncoated cermet grade is optimised for finishing and continuous cuts with small depths of cut; for heavy interrupted or roughing applications, a different grade with a more robust chipformer would be recommended.
