DCGT070204 NS9530 Tungaloy indexable insert — uncoated cermet, 0.4 mm radius

DCGT070204 NS9530 Tungaloy is an ISO‑standard turning indexable insert designed for finishing steel components with a sharp cutting edge and low cutting forces.

• Uncoated cermet grade NS9530
• Fine finishing for steel components
• Sharp cutting edge for low cutting forces
• Rhombic ISO insert 07 with 7° clearance

Precision finishing for demanding turning tasks

The NS9530 grade is an uncoated cermet developed for finishing applications where surface quality and dimensional control are critical. The insert delivers a consistently sharp cutting edge, which reduces cutting forces and helps to achieve superior surface finishes on steel. Using a small 0.4 mm corner radius supports tight tolerance profiles and minimises vibration in light, continuous cuts. The result is reliable component quality with reduced rework and improved throughput.

Stable cutting performance in continuous cuts

Designed as an ISO rhombic insert (07 size) with a 7° clearance, the geometry promotes stable chip evacuation and consistent contact conditions between tool and workpiece. The one‑sided chipbreaker assists in forming short, controlled chips for continuous turning, lowering the risk of built‑up edge and improving process stability. This combination of grade and geometry is particularly suitable for low‑depth finishing passes where repeatable surface integrity and machining economy are priorities.

Compatibility, mounting and practical benefits

The insert is supplied in the ISO designation DCGT070204 with a cylindrical clamping hole plus single‑side countersink (40°–60°), ensuring secure fixation in compatible holders. The 2.38 mm plate thickness and the ISO‑standard form make replacement and tool setup straightforward in standard turning toolholders. Because the insert is specified for finishing, selecting an appropriate holder and cutting parameters matching the NS9530 grade and the workpiece material will maximise tool life and part quality.

FAQ

What machining tasks is this insert best suited for?
This insert is intended for finishing operations in turning, offering NS9530 uncoated cermet performance for steel where low cutting forces and high surface finish are required.

Is the DCGT070204 insert compatible with standard ISO holders?
Yes, the DCGT070204 follows ISO dimensions and secures via a cylindrical clamping hole with a single‑side countersink, compatible with holders designed for rhombic DCGT inserts.

Which materials can be machined with this grade?
The NS9530 finishing grade is optimised for steel; it provides a sharp edge and low cutting forces suited to continuous finishing cuts on steels.

How does the 0.4 mm corner radius influence the result?
A 0.4 mm radius balances edge strength and fine profile control, supporting tight surface requirements while reducing the tendency to vibrate in light finishing passes.

Does the insert include a coating?
The NS9530 grade is supplied uncoated, offering predictable cutting behaviour and excellent surface quality in finishing applications.
