DPMT070202 NS9530 Tungaloy turning insert — rhombic ISO finishing grade, 11° relief

The DPMT070202 NS9530 Tungaloy is an ISO‑standard rhombic turning insert designed for precision finishing on steel and continuous cutting applications, offering a balanced mix of sharp cutting geometry and repeatable clamping.

• ISO rhombic insert DPMT070202, finishing grade
• Uncoated cermet NS9530 for fine surface finish
• 0.2 mm corner radius for small depth cuts
• With cylindrical hole and single-side countersink

Consistent fine finishing with a cermet grade optimised for steel

The main advantage of the NS9530 finishing grade is its combination of a sharp cutting edge and inherently low cutting resistance, which results in a superior surface finish and predictably low forces during machining. As an uncoated cermet, the grade excels in continuous turning and small depth cuts where a stable edge and reduced tendency to build up material are essential. The small 0.2 mm corner radius supports fine finishing passes and helps avoid excessive material removal, which in turn minimises rework and contributes to shorter downstream operations. This makes the insert particularly suitable when consistent dimensional quality and visual surface integrity are priorities.

Secure clamping and ISO compatibility for repeatable setups

The insert’s ISO conformance ensures compatibility with a wide range of holders when the form, relief angle, tolerance class, fastening and thickness are matched. The 11° relief and rhombic geometry produce predictable seating and stable cutting conditions, while the cylindrical hole with single‑side countersink (40°–60°) secures repeatable fastening and orientation in the pocket. A plate thickness of 2.38 mm contributes to reliable mechanical support under finishing loads. Together, these features reduce vibration and positional variance, so tool life and part-to-part consistency are improved across serial production.

Practical chip control and process benefits for productive turning

The single‑sided chipbreaker and the finishing geometry support controlled chip formation for many steels, enabling longer uninterrupted running and easier chip evacuation in typical lathe setups. By selecting a suitable chipbreaker and holder combination, machinists can exploit the insert’s low cutting forces to increase feed or reduce cycle times without compromising finish. The balance between edge sharpness and material robustness supports stable machining windows and fewer in‑process adjustments. Backed by Tungaloy’s manufacturing standards, the insert integrates into machining strategies that prioritise efficiency, reproducibility and surface quality.

FAQ

What materials is this insert suitable for? The DPMT070202 NS9530 insert is formulated as a finishing grade for steel; the uncoated cermet composition is optimised for continuous turning and fine surface requirements on steel components.

How does the small corner radius affect machining? A 0.2 mm corner radius enables small depth cuts and refined surface finishes while reducing the risk of excessive cutting forces, making the insert suitable for precision finishing passes.

Which holder features are required for correct fitting? Compatibility depends on matching the insert form, tolerance class, fastening method, size and thickness; the cylindrical hole with single‑side countersink ensures correct seating and repeatable clamping in a suitable holder.

Can this insert be used for both external and internal turning? Yes, the geometry and finishing grade are appropriate for both external and internal turning where fine surface quality and low cutting forces are required.

What advantage does the uncoated NS9530 grade provide over coated grades? The uncoated NS9530 cermet grade offers a very sharp cutting edge and predictable behaviour in continuous cuts, delivering high surface quality in finishing operations without the variable thermal effects of some coatings.
