DNMG 150402 NS9530 — DNMG indexable turning insert, uncoated cermet, 0.2 mm radius (Tungaloy)

DNMG150402 NS9530 is an ISO‑standard indexable insert designed for precision external and internal turning, optimised as a finishing grade for steel with a sharp cutting edge and low cutting forces

• Uncoated cermet for high surface finish
• Sharp cutting edge with low cutting forces
• Optimised for continuous cuts and small depths
• ISO DNMG150402 shape with cylindrical hole

Greater part quality through lower cutting forces

The uncoated cermet grade NS9530 is formulated for finishing operations where surface quality and dimensional consistency are priorities. Compared with roughing grades, this insert reduces cutting forces and vibration, which in turn diminishes tool marks and enhances reproducibility of turned components. The combination of a sharp cutting edge and a small 0.2 mm corner radius supports fine feed strategies and helps achieve tight surface roughness targets without excessive tool pressure.

Designed geometry for secure mounting and predictable performance

ISO conformity of the DNMG form simplifies toolholder selection and ensures predictable seating in a matching carrier. The ISO DNMG150402 geometry with a cylindrical hole and rhombic plate form provides repeatable clamping, while the 0° relief angle and 55° lead angle help maintain a steady cutting direction and chip flow. This engineered geometry reduces setup time and supports consistent results across series production, improving overall process reliability.

Material and edge concept explained for non‑specialists

A cermet cutting material combines ceramic and metallic phases to deliver a very fine edge and good wear behaviour when finishing steel. The uncoated nature of this grade emphasises the sharpness of the edge rather than thermal barrier properties, which is beneficial in continuous, low‑to‑medium cutting speed finishing operations. The double‑sided chipbreaker further assists in creating short, controllable chips for uninterrupted turning and easier machine handling.

Productivity and application guidance for production environments

When used for external and internal turning with small depths of cut, the insert contributes to shorter cycle times through improved cutting stability and less secondary finishing. The rhombic form and optimised chip control minimise rework and support predictable tool life in stable setups. For best results, match the insert to a compatible holder considering form, relief, tolerance class, fastening method, size and thickness; this ensures full benefit from the insert’s geometry and the NS9530 finishing properties.

FAQ

What materials is this insert intended for?
The DNMG150402 NS9530 insert is a finishing grade optimised for steel and comparable workpiece materials where a sharp edge and low cutting forces are required.

Can the insert be used for both external and internal turning?
Yes, the geometry and chip control of this DNMG form make it suitable for both external and internal turning operations when matched with the correct holder.

How does the uncoated cermet grade affect cutting parameters?
Uncoated cermet like NS9530 favours lower cutting forces and a sharper edge; feed and speed should be tuned for finishing, with attention to stable conditions to exploit its surface‑quality advantages.

Is the insert indexable on both sides?
The item features a double‑sided chipbreaker, allowing indexable use as per the DNMG form and standard clamping practice.

Which insert dimensions determine holder compatibility?
Compatibility depends on form (DNMG), size (15), thickness (4.76 mm), hole style (cylindrical) and relief angle; these parameters should match the chosen toolholder specification.
