DCGT 11T304 NS9530 — Tungaloy indexable turning insert, cermet finishing grade

The DCGT11T304 NS9530 Tungaloy indexable insert is a rhomboid ISO‑design insert for precision finishing in turning applications, optimised for low cutting forces and high surface finish on steel.

• Cermet NS9530 for superior surface finish
• ISO rhombic insert, 7° relief for finishing
• Cylindrical hole with single‑side countersink
• Suitable for continuous cuts and small depths

Fine finishing and consistent surface quality with cermet technology

The insert is produced in an uncoated cermet grade (NS9530), which combines a sharp cutting edge with wear resistance to deliver a high‑quality finish on steel. For finishing passes where low cutting forces and excellent surface integrity are required, the material composition of the grade reduces built‑up edge formation and preserves edge geometry over repeated short engagements. This results in predictable component surfaces and reduced rework, improving process reliability in serial production and precision turning tasks.

Designed for reliable fitment and predictable machining outcomes

Compliance with the ISO designation DCGT11T304 ensures straightforward compatibility with ISO‑style holders and boring bars; fit is governed by insert form, relief angle, tolerance class, attachment method, size and thickness. The rhombic form with a 55° lead angle and 7° relief angle is tailored for external and internal finishing cuts. The insert’s cylindrical hole with a single‑side countersink (40°–60°) simplifies clamping and repeatable seating, so assembly time is minimised and repeatability between tool changes is enhanced.

Process benefits and suggested use cases

This indexable cutting solution is optimised for finishing on steel where continuous cutting and small depths of cut are typical. The 0.4 mm corner radius balances edge strength with the ability to produce fine profiles and maintain close dimensional tolerances. The one‑sided chipbreaker assists chip formation for finishing passes, promoting steady chip flow and reducing the risk of surface damage. For customers aiming to increase throughput without sacrificing surface quality, the combination of cermet grade NS9530 and ISO‑compliant geometry offers an efficient finishing option for turned components.

FAQ

What materials is this insert intended for?
The DCGT11T304 NS9530 insert is specified as a finishing grade for steel workpieces; the NS9530 cermet is optimised for low cutting forces and high surface finish on steel.

How does the cermet grade affect machining performance?
The uncoated cermet composition of the NS9530 grade provides a sharp, wear‑resistant cutting edge that maintains surface integrity during continuous finishing cuts, reducing built‑up edge and improving consistency.

Which holders and clamping systems fit this insert?
The insert follows the ISO DCGT11T304 geometry; compatibility depends on holder form, relief angle, tolerance class, attachment method, size and thickness — the cylindrical hole with a single‑side countersink supports standard clamping arrangements.

Is this insert suitable for internal turning as well as external?
Yes, the rhombic form and 55° approach angle make the insert suitable for both external and internal finishing operations, especially when small depths of cut and continuous cutting are used.
