DCMT 11T308 AH6225 DCMT11T308 — Tungaloy turning insert, rhombic 55°

DCMT11T308 AH6225 is an ISO-standard indexable turning insert for general turning; designed for medium machining of stainless steels with a sharp, stable cutting edge and one-sided chipbreaker.

• PVD-coated carbide grade AH6225
• Universal for stainless steels
• Rhombic 55° geometry
• Cylindrical hole with 40°–60° countersink

Precise performance where stability matters

The insert delivers consistent cutting due to its PVD-coated carbide matrix and a grade tailored for stainless steels. The combination of a finely tuned cutting edge and the AH6225 grade produces stable chip formation under variable conditions, which reduces rework and improves component quality. As an ISO-format indexable solution, it supports reproducible results in serial production and contributes to predictable tool life and process stability.

Secure clamping and geometric advantages

The rhombic 55° shape and the cylindrical hole with single-side countersink (40°–60°) ensure reliable seating in compatible holders. The certified geometry, together with a 7° relief angle and a plate thickness of 3.97 mm, minimises unexpected movement during cuts, enabling secure clamping and straightforward insert indexing. Compatibility to the holder depends on form, relief angle, tolerance class, fastening, size and thickness, so matching the insert to the correct external holder ensures optimal clamping and performance.

Coating and grade explained for practical benefit

The PVD coating on this indexable insert increases wear resistance while preserving a sharp edge, which is particularly beneficial when machining austenitic stainless steels. The AH6225 grade is engineered to give a balance between edge sharpness and robustness for medium-duty turning; this means fewer interruptions for insert changes and a more economical production flow. In practice, the coating reduces adhesion and built-up edge, improving surface finish and extending the useful life of the cutting edge.

Application guidance for reliable throughput

Intended for external and internal turning, the insert performs best when paired with a holder and clamping set that match the ISO designation and geometry. The 0.8 mm corner radius provides a compromise between strength and surface finish; choose this radius for medium-strength finishing and light semi-finishing passes. For one- or multi-pass operations in stainless steels, select feeds and speeds aligned with the grade’s stability: moderate cutting speeds and steady feeds help avoid chatter and promote reproducible tool life. For setups with changing conditions, the universal nature of the grade simplifies tool selection and inventory management.

FAQ

What materials is this insert suitable for?
The DCMT11T308 AH6225 Tungaloy insert is designed primarily for machining stainless steels and offers stable chip formation and good edge performance for medium turning operations.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; the DCMT11T308 AH6225 insert couples with standard ISO turning holders that accept rhombic 55° plates.

How does the AH6225 grade affect machining results?
The AH6225 PVD-coated grade combines a sharp cutting edge with wear resistance to reduce built-up edge and improve surface finish in medium-duty stainless steel turning with the DCMT11T308 insert.

What is the purpose of the 0.8 mm corner radius?
A 0.8 mm corner radius on the DCMT11T308 insert provides a balance between cutting-edge strength and achievable surface finish, suitable for finishing and light semi-finishing passes.

Are there any special mounting considerations for the insert?
Ensure the insert seats correctly in a matched holder and that the fastening torque and clamping parts are appropriate for ISO rhombic inserts; correct seating prevents movement and secures repeatable performance for the DCMT11T308 AH6225.
