DCMT 11T308 AH6225 – Tungaloy indexable turning insert for turning

A DCMT11T308 AH6225 indexable turning insert engineered for reliable external and internal turning of rostfreier Stahl in medium-duty and variable conditions

• PVD-coated carbide grade AH6225
• Optimised for rostfreier Stahl machining
• 55° rhombic geometry for versatile turning
• 0.8 mm nose radius for balanced finish and strength
• Cylindrical hole with 40°–60° countersink

Consistent chip control for improved process reliability

The combination of a PVD-coated surface and AH6225 carbide substrate delivers stable cutting behaviour when machining rostfreier Stahl. The coating reduces built-up edge formation while the carbide core preserves a sharp cutting line under changing conditions, which translates into fewer interruptions for tool changes and a more predictable production rhythm. By choosing a grade designed for stainless applications, the cutting edge maintains performance across variable feed and speed settings, improving overall process efficiency and reducing scrap rates.

Geometry that balances finish and edge security

The rhombic 55° geometry and a 0.8 mm corner radius are tailored to offer a compromise between surface finish and mechanical strength. The insert's shape distributes cutting forces efficiently, enabling good access for turning profiles while the modest nose radius contributes to a consistent surface without compromising the edge under intermittent cuts. A 3.97 mm plate thickness supports secure clamping and a stable cutting position, while the cylindrical hole with a one-sided countersink (40°–60°) ensures repeatable seating and torque transmission in standard ISO holders.

System compatibility and straightforward integration

Manufactured to ISO norms, this indexable insert integrates into common turning tool systems. Compatibility depends on form, relief, tolerance class, fastening, size and thickness; the typical system includes the insert itself, a matching external holder or boring bar, a shim or clamping set and replacement screws. Selecting the correct chipbreaker and grade according to material, machining strategy and machine stability is decisive: the single-sided chipbreaker of this insert promotes controllable chip formation in many turning tasks and simplifies process setup.

Practical benefits and intended applications

Designed for external and internal turning, the insert suits medium machining of rostfreier Stahl where a sharp, wear-resistant edge is required. The PVD finish supports reduced adhesion and improved surface integrity, leading to steadier tool life and consistent part quality. For production environments where repeatability and predictable maintenance intervals matter, this option helps to lower downtime and stabilise cycle time. The insert is particularly apt for shops seeking a universal solution for stainless applications without overly specialised cutting parameters.

FAQ

What materials is this insert best suited for?
The DCMT11T308 AH6225 insert is optimised for machining rostfreier Stahl; the PVD-coated AH6225 grade provides improved resistance to adhesion and steady cutting behaviour in stainless applications.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief, tolerance class, fastening, size and thickness; the insert fits standard ISO rhombic turning holders and can be used in external holders or boring bars when the clamping geometry matches.

What is the function of the one-sided chipbreaker?
The single-sided chipbreaker promotes controlled chip formation during turning, which helps maintain consistent cutting forces and a predictable surface finish when machining rostfreier Stahl.

How does the 0.8 mm nose radius affect machining?
A 0.8 mm corner radius offers a balance between surface finish and edge strength, delivering a reliable finish on turned parts while providing sufficient edge support for medium machining operations.
