DPMT11T308 AH6225 Tungaloy turning insert — PVD-coated carbide, 0.8 mm radius

DPMT11T308 AH6225 is an ISO rhombic turning insert designed for external and internal turning of stainless steels and general machining where a sharp, stable cutting edge is required

• ISO rhombic insert, 55° cutting geometry
• PVD-coated carbide grade AH6225 for stainless steels
• 0.8 mm nose radius for reliable profile control
• With cylindrical hole and single-sided countersink
• Compatible with standard ISO turning holders

Optimised for reliable stainless-steel turning and stable machining

The insert’s PVD-coated carbide grade AH6225 combines wear resistance with an engineered cutting edge to deliver consistent performance in changing conditions. This universal grade is developed for stainless steels, providing a balance between edge sharpness and stability so that moderate feeds and interrupted cuts remain controllable. The result is fewer edge failures and longer effective tool life, which supports predictable cycle times and reduced scrap rates.

Secure seating, predictable chip formation and easy inspection

The ISO rhombic form and the specified 55° geometry ensure stable seating in ISO-compatible holders; compatibility is determined by shape, clearance angle, tolerance class, clamping method, size and thickness. The insert’s 0.8 mm nose radius improves profile accuracy while limiting chatter on slender workpieces. The single-sided chipbreaker and the axial hole with a cylindrical bore and one-sided countersink (40°–60°) promote repeatable chip control and straightforward inspection during tool changes.

Clear system integration and practical workshop benefits

An indexable insert always works as part of a system: the insert, the matching holder or bar, clamping pad and fastening screw. The measured dimensions — 11 mm inscribed size, 3.97 mm thickness and standard ISO form — make it straightforward to select compatible tooling components. Using a proven PVD coating minimises built-up edge when machining stainless steels and reduces the need for frequent regrinds, supporting higher uptime and lower overall machining cost per component.

FAQ

What materials is this insert intended for?
The DPMT11T308 AH6225 insert is formulated for machining stainless steels, with the PVD-coated carbide grade AH6225 delivering a compromise of sharpness and edge stability for moderate cutting conditions.

How does the AH6225 coating improve performance?
The PVD coating on the AH6225 grade enhances wear resistance and reduces adhesion when turning stainless steels, helping the insert maintain a sharp edge and lowering the frequency of tool changes.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, clamping and the insert size and thickness; the DPMT11T308 is ISO-standard and fits ISO-compatible turning holders designed for rhombic inserts of size 11.

What advantage does the 0.8 mm nose radius offer?
A 0.8 mm radius provides improved profile control and strength at the cutting edge, reducing the risk of edge chipping while maintaining acceptable surface finish for many external and internal turning tasks.

Is the insert suitable for interrupted cuts or variable stability conditions?
Yes — the AH6225 grade is intended as a universal solution for variable conditions, offering a stable cutting edge that copes better with interruptions than very sharp, fragile grades.
