DNMG 110408 AH6225 turning insert (55° rhombic, PVD-coated) — Tungaloy

DNMG110408 AH6225 is an ISO-standard indexable insert for turning, optimised for stainless steels and medium-duty machining.

• PVD-coated carbide AH6225 grade
• Optimised for stainless steel machining
• 55° rhombic shape with 0° clearance
• Double-sided insert with cylindrical hole

Consistent edge performance for stainless steel turning

The combination of PVD-coated surface treatment and AH6225 grade carbide creates a balance between a sharp cutting edge and wear resistance, especially in demanding stainless steel applications. The coating increases thermal and chemical resistance, which helps to reduce built-up edge under variable cutting conditions. As an ISO-style indexable insert, the component supports predictable tool life and reduces the frequency of unscheduled tool changes, translating to improved machine uptime and process reliability.

Geometry and clamping that deliver dimensional repeatability

The 55° rhombic design with a 0° clearance angle provides a stable seating in compatible holders and promotes steady axial and radial engagement during turning operations. The insert features a 0.8 mm corner radius and a plate thickness of 4.76 mm, giving a useful compromise between strength and edge detail for medium cuts. The cylindrical hole and the double-sided configuration simplify rotation and re-indexing, while the rhombic form supports both external and internal turning when matched to the correct holder and tolerance class. Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness.

Reduce inventory complexity and increase shop productivity

Using a universal grade aimed at stainless steels reduces the need for multiple specialised inserts, supporting better stock management and quicker set-ups. The ISO-standard format and the double-sided design offer economical use of cutting edges and straightforward replacement procedures, which together lower cost per component. Stable chip formation and a reliable cutting-edge geometry help to maintain consistent surface finish and dimensional accuracy, making this insert suitable for mixed-batch production and shops aiming for predictable, repeatable results.

FAQ

Is this insert suitable for machining stainless steels?
The DNMG110408 AH6225 indexable insert is designed as a universal grade for stainless steels, combining a PVD-coated carbide with a geometry that reduces built-up edge in such materials.

What is the advantage of the AH6225 grade?
AH6225 offers a sharp yet stable cutting edge for medium machining; the PVD coating improves wear resistance and heat tolerance for extended, consistent performance with the DNMG110408 insert.

How is the insert clamped and located in the holder?
The insert has a cylindrical hole and ISO rhombic form; secure clamping depends on matching holder form, clearance, tolerance class, fastening, size and thickness for repeatable seating.

Can the DNMG110408 be re-indexed for multiple edges?
Yes, the insert is double-sided and reversible, allowing rotation to present fresh cutting edges and thus extend usable life per insert.

What cutting tasks is the insert optimised for?
This PVD-coated carbide insert is optimised for medium-duty turning operations on stainless steels and similar alloys, providing a compromise between finish quality and edge robustness.
