DNMG 110404 AH6225 Tungaloy ISO turning insert — PVD-coated carbide, 55°

The DNMG110404 AH6225 Tungaloy insert is an ISO rhombic, double-sided indexable insert engineered for medium turning of stainless steels, balancing a sharp cutting edge with robust wear resistance.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel turning
• Rhombic 55° geometry, corner radius 0.4 mm
• Double-sided design with cylindrical hole

Consistent cutting performance in stainless steel turning

The universal AH6225 grade, delivered as a PVD-coated carbide substrate, is formulated to provide a sharp yet stable cutting edge under variable cutting conditions. The coating reduces abrasive wear and helps maintain edge geometry, which translates into fewer edge changes and more predictable cycle times. The relatively small 0.4 mm corner radius offers a compromise between surface finish and tool strength, enabling reliable medium-depth cuts without sacrificing component quality. Such technical balance supports consistent productivity in batch and job-shop environments.

ISO compatibility and secure clamping for process stability

Compatibility with the machining system depends on form, relief angle, tolerance class, fastening method, size and thickness; the insert’s ISO form and rhombic geometry ensure use with standard 55° turning holders. The cylindrical hole and defined plate thickness of 4.76 mm contribute to secure clamping and repeatable seating, reducing vibration and promoting dimensional consistency. A double-sided design halves stocking variants and allows fast indexation, improving uptime and simplifying tool management in production-oriented workshops.

Lower tooling costs through extended edge life and application flexibility

A universal grade tailored to stainless steels enables broader coverage across varying alloys and temperatures, decreasing the need for constant grade changes. The PVD coating improves wear resistance on the rake face while the substrate supports a reliable cutting edge, which together reduce the frequency of insert replacement and lower cost per component. Choosing the correct chipbreaker and matching the insert’s geometry to the holder delivers better chip control and safer machining, which in turn supports predictable tool costs and higher overall process efficiency.

FAQ

Which materials is this insert best suited for?
The DNMG110404 AH6225 Tungaloy insert is optimised for stainless steels and performs well under the mixed conditions typical of medium turning operations.

How does the insert secure in the holder?
Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness; the DNMG110404’s cylindrical hole and defined thickness ensure reliable clamping in compatible 55° holders.

What are the advantages of the AH6225 grade and PVD coating?
AH6225 combined with a PVD-coated carbide substrate offers improved wear resistance and a stable cutting edge, reducing edge changes and providing predictable tool life in varying conditions.

Is the insert indexable to extend edge life?
Yes — the double-sided design of this rhombic insert allows indexing to a fresh cutting edge, extending usable life and reducing stocking complexity for workshop operations.
