DPMT070202 AH6225 DPMT turning insert for turning – Tungaloy

The DPMT070202 AH6225 is an ISO-standard rhombic indexable insert with a 55° included angle, designed for reliable external and internal turning, especially on stainless steels.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• Rhombic 55° geometry, 0.2 mm corner radius
• Cylindrical hole with single-sided countersink

Consistent cutting performance for stainless steels

The combination of a PVD-coated surface and the AH6225 carbide delivers a sharp yet stable cutting edge, balancing wear resistance and edge acuity for medium-duty machining. This composition improves chip control and helps maintain a predictable tool life when working with stainless steels, where built-up edge and work hardening are common concerns. Selecting this grade reduces rework and stabilises process output, which supports higher uptime and fewer unplanned tool changes.

Secure, ISO-compatible fit for dependable clamping

As an ISO-standard insert, compatibility with holders depends on form, clearance, tolerance class, fastening method, size and thickness; this insert is supplied in the widely used 07 size with a 55° rhombic form and a 0.2 mm corner radius, offering a versatile cutting geometry. The cylindrical hole with one-sided countersink (40°–60°) ensures positive seating and repeatable clamping in matching toolholders. A plate thickness of 2.38 mm and an 11° relief angle contribute to rigidity and support under moderate cutting forces, reducing vibration and improving surface finish in both external and internal turning operations.

Application guidance to increase productivity and reduce risk

This indexable insert is intended for external and internal turning in variable conditions; the single-sided chipbreaker supports predictable chip formation when paired with a suitable holder and cutting parameters. For best results, match the chipbreaker and grade to the workpiece material and machine rigidity: the AH6225 grade is a universal choice for stainless steels and performs well where conditions change between interrupted cuts and continuous cuts. Using this insert can lead to more consistent component quality and reduced cycle time when integrated into a process that considers feed, depth of cut and workholding stability.

FAQ

What materials is this insert optimised for?
The DPMT070202 AH6225 insert is optimised for stainless steels; the AH6225 PVD-coated grade is formulated to manage work hardening and deliver consistent results on a range of rostfreie Stähle.

Which geometrical features influence holder compatibility?
Compatibility depends on the insert form, clearance (relief) angle, tolerance class, fastening method, size and thickness; the 55° rhombic form, 2.38 mm thickness and cylindrical hole with countersink on this insert determine the matching holder specifications.

Can this insert be used for both external and internal turning?
Yes, the indexable design and geometry make the insert suitable for both external and internal turning when paired with an appropriate holder and cutting parameters.

How does the AH6225 grade improve machining stability?
The AH6225 grade combines a PVD coating with a substrate optimised for a sharp but stable cutting edge, improving chip formation and extending usable edge life under medium machining conditions.

What mounting details should be checked before first use?
Ensure the toolholder accepts a 07-size rhombic insert, secures the insert via the cylindrical hole/countersink arrangement, and that clamping parts (shim/clamp and screw) match the ISO mounting standard for repeatable seating.
