DCGT11T300 SH725 indexable turning insert — Tungaloy, 55° rhombic geometry

The DCGT11T300 SH725 is an ISO-standard indexable insert designed for general turning applications, suitable for external and internal operations where robustness and edge stability are required.

• DCGT 55° rhombic cutting geometry
• SH725 coated carbide for durable cutting edges
• 7° clearance angle for reduced flank contact
• Cylindrical hole with single countersink 40°–60°

Consistent cutting performance with a tough coated carbide grade

The combination of the SH725 coating and carbide substrate provides a balance of toughness and wear resistance that supports repeated indexation and long runtimes under variable engagement conditions. The one-sided chipbreaker improves chip control for many turning tasks, reducing interruptions and helping to protect the toolholder from irregular chip flow. Because the grade is optimised for smaller tools and changing cut conditions, the insert is particularly suitable where stable cutting edges are needed to maintain dimensional accuracy and surface finish over multiple passes.

Secure clamping and predictable geometry for reliable results

Manufactured to ISO dimensions, this insert’s 55° rhombic form and 7° clearance angle influence approach behaviour and contact area with the workpiece, which in turn affects cutting forces and surface quality. The insert measures 11 (size designation) with a thickness of 3.97 mm, and the central cylindrical hole with single countersink (40°–60°) ensures reliable seating and repeatable clamping in compatible holders. Compatibility depends on the holder’s form, rake/freedom angles, tolerance class, fastening system, size and thickness; selecting a matching external holder or boring bar is essential for safe, vibration-free operation.

System-level efficiency and practical application guidance

Used as a component of a complete tooling system — insert, appropriate external holder or boring bar, underlay/clamping set and spare screws — this ISO insert supports productive turning workflows. Its coated carbide construction and chipbreaker design simplify processing across a broad range of steels and mixed materials when the correct grade and chipbreaker are selected. For best results, choose cutting parameters and holder rigidity matched to the workpiece and machining strategy; this conserves tool life and enhances process stability while delivering consistent surface quality and dimensional repeatability.

FAQ

Which applications suit this insert best?
The DCGT11T300 SH725 indexable turning insert is intended for general external and internal turning where a tough, edge-stable SH725 grade is beneficial, particularly with smaller tools or variable engagement conditions.

How does the hole and countersink affect clamping?
The cylindrical hole with a single countersink (40°–60°) ensures stable seating and repeatable clamping in compatible holders, improving concentricity and reducing the risk of insert movement during cutting.

What materials is the insert intended for?
The SH725 coated carbide grade provides balanced toughness and wear resistance suitable across a broad range of common turning materials; select the chipbreaker and cutting data according to the specific workpiece material and machining strategy.

What key measurements determine compatibility with a holder?
Compatibility is determined by the insert’s form (rhombic 55°), 7° clearance, size designation (11), thickness 3.97 mm, tolerance class and the holder’s fastening system.

Can the insert be used on both external and internal operations?
Yes, the ISO-standard geometry and chipbreaker make this insert suitable for both external and internal turning when paired with an appropriate external holder or boring bar.
