DCGT11T301 AH725 DCGT turning indexable insert — Tungaloy

The DCGT11T301 AH725 is an ISO-standard rhombic indexable insert for external and internal turning, offering a universal, fracture-resistant grade for steel and stainless steels.

• PVD-coated AH725 carbide grade
• Universal for steel and stainless steel
• Rhombic 55° geometry for versatile turning
• 0.1 mm nose radius; 3.97 mm thickness

Increased process reliability from a universal grade

The combination of PVD-coated carbide and the AH725 grade provides a balanced performance for mixed-production environments. This fracture-resistant grade is engineered to maintain a stable cutting edge under changing workpiece materials and in operations where smaller tool sizes or interrupted cuts occur. Stable chip formation reduces unplanned downtime and contributes to predictable tool life, which in turn supports improved machining economics and consistent production output.

Geometry that improves accuracy and surface quality

A rhombic 55° geometry with a 0.1 mm nose radius delivers a blend of versatility and finishing capability. The small radius aids fine surface finishes and light finishing passes, while the insert thickness of 3.97 mm and the 7° relief angle ensure mechanical stability during heavier engagement. The single-sided chipbreaker is optimised for common turning operations and helps control chip flow; the result is reduced rework and more consistent part quality. The insert’s ISO conformity guarantees straightforward selection when replacing or specifying tooling for existing holders.

Compatibility and practical mounting for reliable clamping

The insert fits ISO turning systems where compatibility is determined by shape, relief angle, tolerance class, fixing method, size and thickness. A cylindrical hole with one-sided countersink (40°–60°) provides secure clamping when combined with the correct seat pad or clamping kit and replacement screws. For assembly, match the insert geometry to the corresponding external holder or boring bar and verify the seat and screw type. Selecting a chipbreaker and grade tuned to the workpiece material optimises cutting forces and surface integrity in turning and internal boring applications.

FAQ

Is this insert suitable for stainless steels?
Yes. The DCGT11T301 AH725 insert by Tungaloy is formulated as a universal, fracture-resistant grade specifically suitable for steel and stainless steels, making it a reliable choice where mixed materials are processed.

Which holders and seats are compatible with this insert?
Compatibility follows ISO standards: the insert requires a matching holder or boring bar that corresponds to the rhombic form, relief angle, tolerance class, fixation method, size and thickness indicated for the DCGT11T301 AH725.

What surface finish can be achieved with the 0.1 mm radius?
A 0.1 mm nose radius assists in achieving fine surface finishes on turning passes; combined with the PVD coating and correct cutting data, the result is improved surface integrity and reduced risk of built-up edge.

Is the AH725 grade suitable for interrupted cutting or small tools?
The AH725 grade is designed to be fracture-resistant and is therefore well suited to applications with interrupted cuts, operations using smaller tools, or where high process security is required.

How is the insert secured in the holder?
The insert features a cylindrical hole with a one-sided countersink (40°–60°), requiring the appropriate pad, clamping set and replacement screws to ensure secure and repeatable clamping.
