DPMT 11T302 AH6225 turning insert by Tungaloy — PVD-coated carbide, rhombic form, 11° relief

DPMT11T302 AH6225 is a compact, ISO-standard indexable turning insert for general-purpose external and internal turning, suited to medium-duty operations and varying material conditions

• PVD-coated carbide for durable cutting edges
• Universal grade optimised for stainless steels
• ISO-compatibility for standard toolholders
• Rhombic shape with 11° relief for versatile turning

Durable, sharp cutting edge for stainless steels

The combination of PVD-coated carbide and the AH6225 grade provides a balance of a sharp cutting edge and robust edge stability under fluctuating cutting conditions. The coating reduces adhesion and heat at the cutting interface, which improves wear resistance and helps maintain a consistent profile over long runs. For machining austenitic or other stainless steels, the insert’s geometry and substrate reduce built-up edge tendencies, contributing to fewer interruptions and more predictable productivity.

Predictable chip control and improved process stability

A single-sided chipbreaker matched to the insert form ensures controlled chip formation during both external and internal turning. Stable chip formation reduces the risk of recutting and surface damage, which directly supports higher throughput and less rework. The insert’s moderate corner radius of 0.2 mm gives a compromise between edge strength and surface finish, enabling reliable component tolerances while extending effective tool life under variable feeds and depths of cut.

ISO-standard dimensions that simplify tool selection

Designed as an ISO-indexable plate, compatibility with the holder depends on form, relief angle (11°), tolerance class, fixation style and thickness. The rhombic plate form and the 55° geometry offer flexibility across turning applications, while the plate thickness of 3.97 mm and the central hole with a cylindrical bore plus single-sided countersink (40°–60°) ensure secure clamping and repeatability in assemblies. Choosing an ISO-standard insert reduces setup time and inventory complexity for mixed-machine environments.

Application guidance for reliable results

This insert performs best in medium machining scenarios where a combination of edge fidelity and stable cutting action is required. Select the cutting parameters conservatively at first and increase feed or speed as the process proves stable; monitor for signs of built-up edge on stainless batches. The insert is suitable for both external and internal turning when paired with the appropriate holder and clamping set. For applications where consistent surface quality and long tool life are priorities, this indexable plate is a practical choice that balances performance and economy — the DPMT11T302 AH6225 name denotes its ISO form, grade and intended use.

FAQ

What materials is this insert suitable for?
The DPMT11T302 AH6225 insert is formulated as a universal grade for machining stainless steels, delivering a compromise of sharpness and edge strength for medium-duty turning.

Which clamping and holder characteristics determine compatibility?
Compatibility depends on the insert form, relief angle (11°), tolerance class, fixation type, plate size and thickness; ensure the holder accepts ISO rhombic plates with the specified central hole and countersink.

How does the PVD coating affect performance?
The PVD coating on the AH6225 substrate reduces adhesion and heat at the cutting zone, improving wear resistance and extending usable cutting life under variable conditions for turning operations.

Is the insert suitable for internal turning as well as external turning?
Yes, the rhombic form and chip control design make this insert suitable for both external and internal turning when paired with a compatible holder and correct setup.

What cutting edge preparation is recommended for good surface finish?
A 0.2 mm corner radius provides a balance between edge strength and surface finish; starting with modest feed rates and verifying stability on trial cuts helps optimise finish and tool life.
