DCMT11T308 AH6225 Tungaloy indexable turning insert — PVD‑coated carbide for turning (ISO 11T308)

A DCMT11T308 AH6225 indexable insert designed for precision external and internal turning, optimised for stainless steels and variable workshop conditions

• PVD‑coated carbide AH6225 for stainless steels
• Universal grade for medium‑condition turning
• ISO DCMT11T308 format for easy replacement
• Cylindrical hole with one‑side countersink (40°–60°)

Consistent cutting performance for stainless‑steel turning

The combination of a PVD‑coated surface on a carbide substrate and the AH6225 grade produces a cutting edge that is both sharp and robust, which is important when machining stainless steels under changing conditions. This specification reduces edge wear and helps to maintain a predictable tool life during medium‑duty turning. The one‑sided chipbreaker is tailored to generate controllable chips and a stable chip flow, which in turn supports steady cutting forces and improved surface finish.

Geometry that simplifies setup and increases stability

The insert follows the ISO 11T308 format and a rhombic outline with a 55° included angle, enabling versatile approaches for external and internal turning. Key dimensions such as the 0.8 mm corner radius, 3.97 mm thickness and the 7° clearance angle ensure a consistent seating and predictable contact with the workpiece; the cylindrical hole with a single‑side countersink (40°–60°) allows secure clamping in compatible holders. These precise features make it easier to select matching holders and clamping sets and reduce time spent on trial adjustments.

Shop‑floor advantages and system considerations

As part of an ISO insert system, the component integrates with a suitable external holder or boring bar, plus an appropriate shim/clamp set and spare screws to form a reliable tooling assembly. The AH6225 grade offers a broad material capability for stainless steels while keeping economy and process robustness in balance. For everyday production, this results in fewer interruptions, consistent surface quality and an overall improvement in process reliability. The insert is identified as SKU 6947701‑Tungaloy and manufacturer article number TUN6947701 for ordering and inventory control.

FAQ

What materials is this insert intended for?
The AH6225 grade and PVD coating make the DCMT11T308 insert particularly suitable for machining stainless steels, offering a balance between edge sharpness and durability.

How does the insert fasten to a holder?
The insert uses a cylindrical hole with a single‑side countersink (40°–60°) and is designed to be secured with the corresponding clamp or screw system in ISO‑compatible external holders.

What is the corner radius and why does it matter?
The corner radius is 0.8 mm; this small radius supports finer finishing capability while maintaining edge strength for medium cutting conditions.

Is this an ISO‑standard insert and how does that help?
Yes, the DCMT11T308 follows ISO 11T308 format, which simplifies replacement and compatibility checks with standard holders and reduces setup time.

How can the insert be identified for ordering or stock?
Order or reference by SKU 6947701‑Tungaloy or manufacturer article number TUN6947701 to ensure the correct DCMT11T308 AH6225 Tungaloy insert is supplied.
