DCMT 070202 NS9530 turning insert — ISO rhombic finishing insert by Tungaloy

DCMT070202 NS9530 is a finishing turning insert engineered for steel applications, optimised for continuous cuts and small depths of cut to deliver consistently high surface quality.

• Finishing uncoated cermet grade NS9530
• Sharp cutting edge for superior surface finish
• 7° clearance angle for controlled chip formation
• Rhombic 07 form with 0.2 mm corner radius

Achieve consistent high-quality surfaces with a finishing cermet

The NS9530 grade is an uncoated cermet developed for finishing operations on steel, offering a sharp cutting edge that lowers cutting forces and promotes excellent surface integrity. This finishing grade is particularly effective in continuous cutting and when using small feeds and depths of cut, reducing the need for secondary finishing. Compatibility with standard ISO holders ensures predictable performance across various turning systems, while the rhombic geometry supports both external and internal turning tasks.

Secure clamping and ISO system compatibility for repeatable results

Designed as an ISO-standard indexable insert, the component features a cylindrical hole with a one-sided countersink (40°–60°) to allow reliable, repeatable clamping. The insert’s form, clearance angle, tolerance class, fastening and thickness determine holder compatibility; this makes the component straightforward to integrate into established tool systems. The secure seating and standard dimensions facilitate quick index changes and contribute to reduced setup times and stable part-to-part repeatability.

Optimised chip control and machining stability for finishing passes

A single-sided chipbreaker matched to the grade promotes controlled chip formation in continuous cuts, while the 7° clearance angle helps to maintain a clean cutting geometry and minimise rubbing. The small 0.2 mm corner radius supports fine surface finishes without sacrificing edge strength during light finishing passes. Together, these features enable steady cutting behaviour and predictable tool life during high-quality finishing operations on steel.

Practical productivity gains and material application guidance

This insert is intended primarily for turning steel in finishing applications, yielding productive machining and consistent surface results with minimal burr formation. The cemented carbide body and cermet cutting edge provide wear resistance appropriate for low to moderate cutting loads typical of finishing. Integration into a complete turning system — insert, matching external holder or boring bar, shim/clamp set and replacement screws — supports efficient tool management and cost-effective production workflows.

FAQ

What machining tasks is this insert best suited for?
This insert, the DCMT070202 NS9530 by Tungaloy, is best suited for finishing operations in turning, particularly continuous cuts and small depth-of-cut passes on steel.

Is the insert compatible with standard ISO turning holders?
Yes, the insert follows ISO geometry for rhombic turning inserts; compatibility depends on holder form, clearance, tolerance class, fastening, size and thickness.

How does the NS9530 grade affect surface finish?
The NS9530 uncoated cermet grade provides a sharp cutting edge and low cutting forces, which together produce superior surface quality during finishing operations.

What role does the 0.2 mm corner radius play in finishing?
A 0.2 mm corner radius balances edge strength and the ability to achieve fine surface finishes, making it suitable for final-pass turning where small radii and smooth surfaces are required.

Does the insert require specific clamping hardware?
The insert uses a central cylindrical hole with a one-sided countersink (40°–60°) for secure clamping; standard clamping sets and replacement screws for ISO inserts are applicable.
