DCMT11T304 GT9530 — Tungaloy turning insert (ISO, finishing)

The DCMT11T304 GT9530 is a wear‑resistant cermet indexable insert designed for finishing and light universal turning in stable machining conditions

• Cermet grade GT9530 for extended tool life
• Optimised for finishing and light universal turning
• ISO DCMT 11T304, 55° rhombic geometry
• Cylindrical hole with 40°–60° countersink

Reliable surface quality through a wear‑resistant grade

The GT9530 formulation is a cermet‑based cutting grade engineered to deliver a consistently high surface finish when machining steels. As a finishing‑oriented option, the grade combines abrasion resistance with thermal stability to reduce flank wear during long runs under stable cutting conditions. For shops seeking predictable component quality, the result is fewer reworks and more parts meeting tolerance on first pass thanks to the insert’s ability to sustain a sharp cutting edge for longer.

Predictable cutting behaviour with ISO geometry

The rhombic 55° platform and standardised hole and clamping features provide straightforward compatibility with ISO toolholders. The DCMT11T304 geometry offers a compromise between approach angle and strength, allowing accurate profile control while maintaining sufficient edge support. Because compatibility is governed by form, relief angle, tolerance class, clamping method, size and thickness, adopting an ISO insert simplifies tooling logistics and reduces set‑up time across multiple lathes.

Geometry and micro‑features that support repeatability

Key geometric parameters such as the 0.4 mm corner radius, 7° relief angle and 3.97 mm thickness contribute directly to edge stability and consistent chip formation. A small corner radius favours high‑quality finishes on turned surfaces, while the specified relief prevents rubbing at the flank. These measurable features help machinists select cutting data with confidence and predict the interaction between insert and workpiece for repeatable production results.

Chip control and secure mounting for efficient turning

The insert features a one‑sided chipbreaker and a cylindrical hole with single‑sided countersink (40°–60°) to support reliable clamping and effective chip evacuation. Combined with the carbide substrate, the chip geometry reduces the risk of built‑up edge in finishing passes and aids coolant penetration when used. This structure makes the component suitable for both external and internal turning operations where surface integrity and process stability are priorities.

System integration and handling advantages

As an ISO indexable insert, the part integrates into established tool systems with predictable mechanical interfaces. The standardised form factor eases stock management and interchangeability between holders and boring bars, while the grade’s focus on finishing helps to extend intervals between insert changes. For production environments prioritising uptime, the combination of grade and geometry supports longer continuous runs and simplified tooling choices.

FAQ

Which materials is this insert best suited for?
The DCMT11T304 GT9530 insert from Tungaloy is formulated as a wear‑resistant cermet grade primarily aimed at steels, providing good surface finish and extended life in finishing and light universal turning operations.

How does the GT9530 grade improve tool life?
GT9530 combines abrasion resistance and thermal stability so the cutting edge maintains sharpness longer in stable conditions, allowing the Tungaloy insert to deliver more consistent parts over extended runs.

What holder compatibility should be checked before use?
Compatibility depends on the holder’s form, relief, tolerance class, clamping type, size and thickness; the DCMT11T304 designation conforms to ISO standards, simplifying matching with suitable external holders and boring bars.

What are the important geometric features to consider when setting cutting data?
Focus on the 55° geometry, 0.4 mm corner radius and 7° relief angle along with the 3.97 mm thickness; these parameters influence edge strength, surface finish and recommended feeds and speeds for finishing cuts.

Can this insert be used for internal turning as well as external turning?
Yes, the indexable concept and the insert’s form allow both external and internal turning; select an appropriate holder and ensure secure clamping using the cylindrical hole with single‑sided countersink for internal applications.
