DCGT 11T304 SH730 – Turning indexable insert, Tungaloy

The DCGT11T304 SH730 indexable insert is an ISO‑form rhombic turning insert with a 55° geometry, designed for general external and internal turning with a one‑sided chipbreaker and secure clamping.

• SH730 coated carbide for edge stability
• 55° rhombic form for versatile turning
• 0.4 mm corner radius for fine profiling
• Cylindrical hole with counterbore for secure clamping

Consistent cutting performance for variable conditions

The SH730 grade is a coated carbide designed to combine toughness with sustained edge stability, making it suitable for turning operations that involve fluctuating engagement or intermittent cuts. The one‑sided chipbreaker promotes controlled chip formation and evacuation, which reduces the risk of built‑up edge and contributes to uninterrupted machining cycles. These characteristics support higher process reliability and predictable tool life in series production and jobbing alike.

Secure mounting and ISO compatibility reduce setup risk

The rhombic insert features a cylindrical hole with a single‑sided countersink (40°–60°) that ensures repeatable seating and a secure clamp fit. The insert’s form, relief angle and tolerance class conform to ISO standards, so compatibility with standard ISO holders is governed by geometry and size rather than proprietary fittings. This simplifies inventory management and lowers the effort required when changing inserts between holders.

Geometry and dimensions that add precision to the cut

A 55° lead angle combined with a 0.4 mm corner radius enables fine contouring and reliable finish on both external and internal profiles. The plate thickness of 3.97 mm gives sufficient support for small to medium‑scale turning tools while limiting overhang and vibration. Together, these dimensions balance edge strength and the ability to achieve close tolerance workpieces, particularly in less rigid setups.

Material range and process orientation

The coated grade is engineered for a broad material spectrum, favouring applications where toughness and edge retention are essential. The insert’s properties make it suitable for general turning across a range of steels and cast materials, with the chipbreaker choice allowing adaptation to the workpiece material and machining parameters. Selection of the SH730 grade typically improves process stability in mixed‑batch environments.

Practical benefits in workshop operation

Standardised ISO geometry simplifies insert selection and stockkeeping, while the robust coated carbide core reduces downtime through longer intervals between index changes. The combination of rhombic form, one‑sided chipbreaker and secure hole design reduces the need for frequent adjustments, supporting smoother production flow and easier operator handling. For machines that require frequent tool changes, the insert’s repeatability contributes to faster setup and reduced scrap rates.
