DPMT070208 AH6225 ISO turning insert, PVD‑coated carbide, 55° — Tungaloy

A DPMT070208 AH6225 ISO‑standard rhombic turning insert designed for external and internal turning, combining a sharp yet stable cutting edge with universal performance on stainless steel.

• PVD‑coated carbide AH6225
• Rhombic 07 geometry, 55° cutting angle
• 0.8 mm corner radius for edge stability
• Single‑sided chipbreaker, hole with countersink

Consistent results on stainless steel with a universal grade

The AH6225 grade is a PVD‑coated carbide developed as a universal solution for stainless steel machining. Its substrate and coating combination provides a sharp and stable cutting edge that copes well with medium‑duty cuts and varying conditions, reducing surface defects and improving process repeatability. As a consequence, scrap rates fall and cycle time variability is reduced, delivering measurable gains in production efficiency.

Geometry tuned for flexible turning and edge strength

With a rhombic 07 shape and a 55° cutting angle, the geometry offers a balance between access and mechanical strength. The 0.8 mm corner radius increases edge robustness without sacrificing form accuracy, while the 11° relief and 2.38 mm plate thickness support controlled cutting forces. This combination enables reliable external and internal turning where a compromise between finishing capability and tool life is required.

Predictable chip formation and secure clamping for uptime

The insert features a single‑sided chipbreaker and a cylindrical hole with one‑sided countersink (40°–60°) that promote consistent chip control under many conditions. The ISO‑standard layout simplifies replacement: the system consists of the insert, a matching holder or boring bar, a backing/ clamp set and replacement screws; holder compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness. Improved chip flow and dependable clamping reduce unplanned stops and make maintenance intervals more predictable.

Practical advantages for daily production and set‑up

As an ISO‑standard indexable insert, this grade supports quick changeover and straightforward inventory management. The combination of PVD coating, stable edge geometry and standardised form enables scalable productivity gains across mixed production runs. For technical clarification on holder matches or cutting data, the technical team can provide machining recommendations to help integrate the insert into existing tool systems.

FAQ

What materials is this insert best suited for?
The DPMT070208 AH6225 turning insert (SKU 6951285‑Tungaloy) is formulated primarily for stainless steel and offers reliable performance across many austenitic and ferritic grades.

Can the insert be used for internal turning operations?
Yes, the rhombic 07 geometry and 55° orientation make the insert suitable for both external and internal turning applications where access and edge strength are required.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius increases the cutting edge strength for medium machining, improving tool life and resistance to chipping while still allowing acceptable surface quality.

What does the chipbreaker and hole design provide?
The single‑sided chipbreaker combined with a cylindrical hole with countersink promotes consistent chip formation and secure clamping, which helps to reduce downtime from unstable chips or poor seat contact.

How is holder compatibility determined?
Compatibility for ISO‑standard inserts depends on holder form, relief angle, tolerance class, fastening method, insert size and thickness; confirm these parameters against the holder specification before selection.
