DNMG150404 AH6225 ISO indexable turning insert by Tungaloy — PVD-coated carbide, 55° rhombic

The DNMG150404 AH6225 is an ISO rhombic indexable insert for external and internal turning, optimised for machining stainless steels in medium cutting conditions.

• PVD-coated carbide AH6225
• Designed for stainless steels
• 55° rhombic geometry with 0.4 mm radius
• Double-sided insert with cylindrical hole

Consistent edge life and material adaptability

The combination of a PVD-coated surface and a wear-resistant carbide substrate provides reliable performance when machining stainless steels under varying conditions. The AH6225 grade is formulated to balance a sharp cutting edge with stability, which translates into uniform surface finish and predictable tool change intervals. For process planners, this means fewer unplanned interruptions and a machining cycle that is easier to reproduce across shifts and machines. The coating also reduces built-up edge tendencies, helping to maintain dimensional accuracy over longer tool life.

Geometry and system compatibility that simplify tooling

The 55° rhombic geometry and a 0.4 mm corner radius deliver a versatile compromise between strength and form accuracy for both facing and profiling operations. As an ISO-standard insert, compatibility with holders is governed by shape, relief angle (0°), tolerance class, fastening, size and thickness; this standardisation ensures simple replacement and consistent clamping forces. The double-sided design with a cylindrical hole enables quick indexing and secure attachment, reducing downtime during regrips or insert changes and improving overall equipment efficiency.

Practical benefits in shop-floor turning operations

Designed for both external and internal turning, the insert supports applications where chip control and a reliable cutting edge are essential. Selecting an appropriate chipbreaker and using the AH6225 grade tailored to the workpiece stability will optimise chip formation and surface quality. The reversible insert format contributes to material savings and lowers per-edge tooling cost, while the robust substrate assists in resisting thermal and mechanical wear during medium-duty operations. For production environments seeking predictable throughput, the Tungaloy indexable insert offers a pragmatic mix of longevity and performance.

FAQ

What materials is this insert intended for?
The DNMG150404 AH6225 insert from Tungaloy is intended primarily for stainless steels and performs well in medium cutting conditions where a balance of sharpness and edge stability is required.

Is the insert compatible with standard ISO holders?
Yes, the ISO form of the DNMG150404 AH6225 means compatibility with ISO holders is determined by shape, relief angle, tolerance class, fastening, size and thickness so it can be used with matching ISO clamping systems.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius on the DNMG150404 AH6225 increases edge strength compared with smaller radii, improving resistance to chipping while still allowing good profile definition on typical turning tasks.

Does the insert allow quick indexing and secure clamping?
The double-sided design with a cylindrical hole provides secure fixation and enables quick indexing of the cutting edge, which supports reduced downtime during insert changes.
