DCGT 070202 NS9530 ISO turning insert – finishing grade by Tungaloy

DCGT 070202 NS9530 is a rhombic ISO turning insert engineered for precision external and internal turning, optimised for finishing steel components.

• Sharp cermet grade NS9530 for fine finishing
• Rhombic 07 form with 55° cutting angle
• 0.2 mm corner radius for precise contours
• Cylindrical hole with 40°–60° countersink

Superior surface finish with low cutting forces

The uncoated cermet NS9530 is specified for finishing of steel where a sharp cutting edge and low cutting forces are decisive. The combination of a fine-grain ceramic phase with metallic bonding gives a stable edge that produces a superior surface finish on continuous cuts and small depth passes. For shops aiming to reduce secondary operations, this insert reduces the need for additional polishing while maintaining consistent dimensional control.

Predictable geometry for repeatable turning results

The rhombic 07 form and a 55° main angle deliver a controlled cutting direction that supports accurate profiles and minimises chatter when paired with appropriate tooling and stable setups. A 0.2 mm corner radius balances edge strength and form fidelity for detailed contours, while the 7° clearance helps reduce rubbing on shoulder faces. These geometric details translate into repeatable part quality and lower scrap rates during finishing cycles.

Clear mounting and chip control for efficient processes

Designed as an ISO turning insert, compatibility with holders is determined by form, clearance, tolerance class, fastening, size and thickness; the insert includes a cylindrical hole with one-sided countersink (40°–60°) for secure clamping and precise location. The single-sided chipbreaker manages chip formation for continuous operations, reducing re-cutting and improving cycle stability. The solid substrate—manufactured from cemented carbide—ensures mechanical strength under finish-cut conditions.

Application focus and process benefits

Intended primarily for turning steel in finishing applications, the insert supports small depths of cut and continuous feed profiles where high surface quality is required. With a plate thickness of 2.38 mm and standard ISO sizing, the component integrates into existing tool systems with minimal adaptation. Choosing this grade helps shops achieve consistent component finish, reduced secondary work and reliable edge behaviour under steady-state feeds.

FAQ

What materials is this insert suited for? The DCGT 070202 NS9530 insert is formulated for finishing steel; the NS9530 uncoated cermet grade provides a sharp edge and good results on continuous cuts.

How is the insert secured in the holder? Clamping is via the cylindrical hole with a one-sided countersink (40°–60°); this design ensures reliable location and stable fastening in ISO-compatible holders.

What cutting geometry helps achieve the surface finish? The rhombic 07 form with a 55° main cutting angle combined with a 0.2 mm corner radius produces a controlled cutting action that supports high-quality surface finishes.

Is this insert suitable for internal and external turning? Yes; the geometry and chip control make the insert appropriate for both external and internal turning operations where finishing performance is required.

Can the insert handle interrupted cuts or roughing passes? The DCGT 070202 NS9530 is a finishing-grade insert optimised for continuous cuts and small depths; for heavy interrupted cuts or heavy roughing, a more robust grade is recommended.
