DPMT11T308 AH6225 indexable turning insert (ISO 11T308, 55°) by Tungaloy

The DPMT11T308 AH6225 is an ISO-form indexable turning insert for external and internal turning, engineered to provide a balanced cutting edge and reliable performance in stainless-steel applications

• PVD-coated carbide grade AH6225
• Optimised for stainless-steel turning
• 55° rhombic form with 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance with PVD-coated grade

The first advantage is the AH6225 grade: a PVD-coated carbide developed to combine a sharp cutting edge with robust wear resistance. This balance reduces edge breakdown during medium machining of stainless steels, which translates into fewer interruptions for tool changes and more predictable component quality. The single-sided chipbreaker contributes to controlled chip formation, helping to avoid entanglement and maintain a steady metal-removal rate. For machinists seeking reliable cycles and repeatable surface finish, this combination supports productivity and a lower cost per part.

Secure clamping and defined geometry for stable machining

Designed to the ISO profile 11T308, the insert’s rhombic shape and 55° approach angle give a versatile geometry for both facing and light profiling. The relief angle of 11°, a 0.8 mm corner radius and a plate thickness of 3.97 mm ensure mechanical stability in the cut while permitting fine edge control. The cylindrical hole with a single-sided countersink (40°–60°) enables precise, repeatable clamping in compatible holders; compatibility is determined by form, relief, tolerance class, mounting, size and thickness. Correct pairing with a matched holder reduces vibration and supports consistent part tolerances.

Practical system approach for workshop efficiency

The insert is intended to be used as part of a complete system: an ISO indexable insert, a suitable external holder or boring bar, a shim/clamping set and spare screws. Selecting the appropriate chipbreaker profile and choosing the AH6225 grade for changing cutting conditions helps maintain tool life and surface integrity during external turning and internal turning tasks. For batch production or one-off workpieces where stainless steels are common, the modular nature of the system simplifies tool inventory and speeds up insert changes, supporting shorter setup times and stable throughput.

FAQ

What materials is this insert best suited for?
The DPMT11T308 AH6225 insert is optimised for machining stainless steels; the AH6225 grade and chipbreaker are chosen for balanced wear resistance and edge sharpness in such materials.

Which cutting operations are intended for this insert?
This indexable turning insert is designed for external turning and internal turning, offering versatility for facing, profile turning and light finishing passes.

How does the insert’s hole and countersink benefit clamping?
The cylindrical hole with a single-sided countersink (40°–60°) on the DPMT11T308 allows precise axial location and secure clamping in compatible holders, improving repeatability and reducing the risk of insert rotation under load.

Is the AH6225 grade suitable for variable cutting conditions?
Yes, the AH6225 PVD-coated carbide grade is formulated to provide a stable cutting edge under changing conditions, making it suitable for workshops with mixed stainless-steel part runs.

Which system components are recommended when using this insert?
A complete system comprises the insert itself, a matched external holder or boring bar, a shim or clamping set and replacement screws to ensure reliable mounting and quick insert changes.
