DCGT 11T301 SH730 ISO turning insert for turning — Tungaloy

A DCGT11T301 SH730 indexable turning insert engineered for external and internal turning where stable cutting edges and compact tool sizes are required

• Coated cemented carbide SH730 grade
• ISO‑standard rhombic insert, 11 mm size
• 0.1 mm corner radius with 7° relief angle
• Cylindrical hole with 40°–60° countersink

Engineered for reliable turning under varying engagement

The SH730 grade is a coated cemented carbide designed to deliver edge stability and durable cutting performance, especially in smaller tooling configurations or when engagement conditions change. The formulation of the grade emphasises toughness and resistance to chipping, which reduces unplanned tool changes and supports longer productive runs. As an ISO turning insert, it provides a consistent datum and repeatable seating in ISO‑compatible holders, translating material properties into measurable productivity gains and lower overall machining costs.

Precision geometry for predictable seating and chip control

Rhombic geometry and ISO conformity ensure the insert seats reliably in the toolholder; compatibility is determined by form, free angle, tolerance class, fastening, size and thickness. The insert measures 11 mm in the standard size class, with a plate thickness of 3.97 mm, a 0.1 mm corner radius and a 7° relief angle. The cylindrical hole with a one‑sided countersink (40°–60°) secures the insert and supports consistent clamp force, which helps maintain cutting stability and repeatable part quality. These dimensional choices balance rigidity and accessibility for a wide range of turning set‑ups.

Practical process benefits and clear handling guidance

A one‑sided chipbreaker on the insert promotes controlled chip formation in typical turning operations and simplifies orientation decisions during tool assembly. For turning tasks that require frequent index changes or that place variable loads on the cutting edge, the coated cemented carbide SH730 grade offers a compromise between wear resistance and fracture toughness. The ISO labelling and standardised form make tool selection and stocking straightforward, while the compact rhombic shape supports both external and internal turning operations with efficient material removal and consistent surface quality.

FAQ

What applications suit this insert best?
The insert is intended for turning operations, both external and internal, where an ISO‑standard rhombic insert and a coated cemented carbide SH730 grade are advantageous.

How is compatibility with a toolholder ensured?
Compatibility depends on form, free angle, tolerance class, fastening, size and thickness; the ISO designation 11T301 helps match the insert to ISO‑compatible holders.

What are the advantages of the SH730 grade?
SH730 is a tough, edge‑stable grade developed for turning, particularly effective in smaller tools or when engagement conditions vary, providing reduced chipping and stable performance.

How does the hole and countersink affect fixing?
The cylindrical hole with a single‑side countersink (40°–60°) ensures secure clamping and correct seating, which supports cutting stability and consistent repeatability.

What does a 0.1 mm corner radius mean for surface finish?
A 0.1 mm corner radius offers a balance between edge strength and the ability to achieve good surface finish; it is commonly used where a compromise between finish and tool life is required.
