DNGG 150408 NS9530 Tungaloy — ISO turning insert, rhombic 55°

The DNGG150408 NS9530 Tungaloy insert is an ISO rhombic finishing grade developed for external and internal turning, optimised to deliver high surface quality on steelwork.

• Uncoated cermet finishing grade NS9530
• 0.8 mm nose radius for high-quality surface
• Rhombic 55° geometry, with cylindrical hole
• 4.76 mm plate thickness for increased rigidity

Fine finishing with low cutting forces and superior surface quality

The insert’s NS9530 uncoated cermet composition and sharp cutting edge are engineered for finishing passes on steel, particularly where continuous cuts and small depths of cut are employed. The material choice produces low cutting forces, helping to reduce workpiece deformation and achieve improved surface integrity. As a consequence, machining sequences that demand tight tolerances benefit from a measurable improvement in finish without increasing process complexity.

Stable clamping and geometry that support repeatable results

The rhombic 55° geometry combined with a 4.76 mm thickness and a 0.8 mm nose radius delivers a balance of accessibility and stiffness. The insert’s cylindrical centre hole enables secure clamping in compatible holders, while the 0° clearance (relief) angle supports a predictable cutting action. These attributes together enhance repeatability in serial production and reduce the need for frequent readjustment, which is especially valuable in batch or lights-out operations.

Seamless integration into ISO tooling systems for efficient setup

Supplied as an ISO-series turning plate, the insert fits into standard indexable tooling systems when the holder’s form, clearance angle, tolerance class, fastening method, size and thickness correspond. The overall system typically comprises an ISO insert, an appropriate outer holder or boring bar, a shim/clamping set and replacement screws. The insert’s double-sided chipbreaker design allows economical indexing and longer on-machine life when the proper chip control and grade are selected for the workpiece and process stability.

Efficiency gains and practical benefits on the shopfloor

By choosing an optimised finishing grade such as NS9530 and the DNGG150408 form, machining cycles can be tailored to favour higher surface quality with modest feeds and shallow depths, reducing rework and downstream polishing. The combination of efficiency and consistent finish makes this insert suitable for precision components where dimensional fidelity and surface appearance are critical. Selecting the correct chipbreaker and ensuring a rigid setup will extend tool life and sustain productivity across repeat batches.

FAQ

Which materials is this grade best suited for?
The DNGG150408 NS9530 Tungaloy insert is a finishing grade optimised for steel; its uncoated cermet composition and sharp cutting edge are tailored for continuous cuts and small depths of cut to achieve high surface quality.

Can the insert be used on both external and internal turning operations?
Yes, the rhombic geometry and the ISO form make the plate appropriate for both external and internal turning when used with a compatible holder and a secure clamping arrangement.

Is the plate indexable on both sides?
The plate is double-sided with a chipbreaker on each side, allowing economical indexing and extending the usable life of the insert in typical turning applications.

How does the 0.8 mm nose radius affect surface finish?
A 0.8 mm nose radius supports finer surface finishes by smoothing tool marks at modest feeds; combined with the NS9530 grade it helps to reduce cutting forces and improve surface integrity in finishing passes.

What determines whether this insert fits a specific holder?
Fitment is governed by the ISO form, relief angle, tolerance class, hole style and plate thickness; the insert requires a holder compatible with the DNGG150408 geometry and the cylindrical hole for correct clamping.
