DCGT 11T308 NS9530 Tungaloy turning insert — DCGT11T308, rhombic 55°

A DCGT11T308 NS9530 indexable turning insert engineered for external and internal turning, optimised for fine finishing and continuous cuts.

• Rhombic insert, 55° angle, 0.8 mm corner radius
• Uncoated cermet grade NS9530 for fine finishing
• Single-sided chipbreaker for continuous cuts
• ISO-standardised insert with centre hole and countersink

Superior finishing with the NS9530 cermet grade

The uncoated cermet NS9530 offers a very sharp cutting edge and reduced tendency to build up material, which directly improves surface quality on steel during finishing operations. Because this grade is designed for continuous cutting and small depth-of-cut strategies, it lowers cutting forces and vibration, resulting in a more stable process window and fewer reworks. The modest corner radius of 0.8 mm supports delicate geometry control, enabling consistent part tolerance and a superior visual finish compared with typical roughing grades. For production environments where finishing quality and repeatability matter, this insert promotes reliable cycle-to-cycle performance without sacrificing edge integrity.

Predictable fit and secure clamping for process reliability

Built to ISO specifications, the insert’s rhombic form and 55° approach angle ensure compatibility with standard turning holders when the form, relief angle, tolerance class, fastening, size and thickness are matched. The design includes a centre hole with a cylindrical bore and a single-sided countersink (40°–60°), providing positive location and secure clamping. A plate thickness of 3.97 mm and the defined 11 mm inscribed size contribute to rigid mounting and consistent tool projection; this reduces chatter and enables predictable tool life. Clear system definition — insert, suitable holder or boring bar, support shim and clamping screw — simplifies tool procurement and changeover planning in a production setting.

Efficient chip control and steady productivity

The single-sided chipbreaker is optimised for continuous cuts, directing chips away from the workpiece to protect the finished surface and reduce secondary operations. With a cutting edge engineered for low cutting forces, the insert helps to extend the life of the holder assembly and maintain stable cutting conditions over long runs. The ISO-standard geometry and sharp edge characteristics make the insert particularly suitable for fine finishing of steels, where both surface integrity and dimensional accuracy are priorities. Combined with the NS9530 composition, the insert balances edge retention and toughness to deliver repeatable results in demanding finishing cycles while supporting efficient throughput.

FAQ

What applications is this insert best suited for?
The DCGT11T308 NS9530 insert is intended for external and internal turning, especially fine finishing of steels where continuous cutting and small depths of cut are used to achieve high surface quality.

How does the NS9530 grade affect finishing performance?
The uncoated NS9530 cermet provides a very sharp edge and low cutting forces, which reduces built-up edge formation and enhances surface finish when using the DCGT11T308 for finishing operations.

Is the insert compatible with standard ISO holders?
Yes — the DCGT11T308 follows ISO geometry; compatibility is determined by matching form, relief angle, tolerance class, fastening method, size and thickness with the chosen holder or boring bar.

What does the single-sided chipbreaker deliver in production?
The single-sided chipbreaker improves chip control for continuous cuts, protecting the finished surface and reducing the risk of rework while maintaining steady productivity.

Which clamping arrangement is required for this insert?
The insert uses a centre hole with a cylindrical bore plus a one-sided countersink (40°–60°) for positive location; secure clamping requires a compatible screw and support shim as part of the holder system.
