DCGT11T302 NS9530 — Tungaloy rhombic turning insert, 11 mm, 0.2 mm corner radius

The DCGT11T302 NS9530 is a rhombic ISO turning insert for finishing operations on steel, offering a sharp cutting edge and low cutting forces for continuous turning and small depths of cut.

• Rhombic shape, 11 mm size
• Sharp cermet grade NS9530 for finishing
• 0.2 mm corner radius for fine surface finish
• Cylindrical hole with one-sided countersink 40°–60°

Achieving consistent, high‑quality surface finishes with cermet technology

The rhombic, small‑edge insert is engineered for precision finishing on steel where surface integrity matters. As an uncoated cermet grade, NS9530 delivers a sharp cutting edge and reduced cutting forces, which lowers vibration and helps maintain dimensional stability during continuous cuts. The small corner radius (0.2 mm) produces minimal scallop height, yielding a finer surface without sacrificing tool life. For shops aiming to increase first‑pass quality and reduce rework, this insert provides a predictable path to improved surface finish and shorter downstream processes.

Geometry and holder compatibility for reliable tool clamping and repeatability

The insert’s ISO DCGT geometry and standardised form ensure compatibility with a wide range of ISO turning toolholders; fit depends on form, relief angle, tolerance class, clamping method, size and thickness. The 11 mm inscribed circle and 3.97 mm thickness offer a stable clamping interface, while the 7° relief angle balances edge strength and chip flow. The central cylindrical hole with a one‑sided countersink (40°–60°) permits secure fastening with standard screws and underplates, aiding repeatable seating and quick indexability. Clear mechanical conformity reduces setup time and supports steady process control on production lines.

Application benefits and selection guidelines for productive finishing

For turning operations on steel where continuous cuts and small depths of cut are typical, the NS9530 finishing grade is optimised: it provides good surface quality with low cutting forces and stable chip formation. The single‑sided chipbreaker supports controlled chips in finishing passes, and the cermet substrate resists built‑up edge at moderate cutting speeds. Select this insert when the priority is surface finish and dimensional accuracy rather than heavy roughing; combining the insert with a rigid holder and appropriate feeds will extend edge life and maintain consistent results across batches.

FAQ

What materials is this insert suited for?
The DCGT11T302 NS9530 insert is intended primarily for finishing on steel and is optimised for continuous cuts with small depths of cut.

Which holder types are compatible with this ISO insert?
Compatibility depends on the holder’s form, relief angle, tolerance class, clamping method, size and thickness; the insert is compatible with standard ISO turning holders designed for DCGT inserts.

How does the 0.2 mm corner radius affect surface finish?
A 0.2 mm corner radius reduces scallop height and produces a finer surface finish, making it suitable for applications where improved surface quality is required.

Is the insert coated or uncoated?
The grade NS9530 is an uncoated cermet finishing grade designed for low cutting forces and a sharp cutting edge.

What fastening style does the insert use?
The insert features a cylindrical hole with a one‑sided countersink (40°–60°) for secure clamping with standard screws and underplates.
