DNMG150404 AH6225 Tungaloy turning insert – ISO indexable insert for turning, 0° relief, 0.4 mm radius

A DNMG150404 AH6225 Tungaloy indexable insert designed for ISO-standard turning, optimised for machining stainless steel with a robust PVD-coated carbide grade

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• ISO DNMG150404 rhombic 55° geometry
• Double-sided design with cylindrical hole
• 0.4 mm corner radius for precise turning

Consistent cutting performance for stainless steel turning

The PVD-coated carbide composition of the AH6225 grade delivers a combination of a sharp, wear-resistant edge and sufficient toughness for medium cutting depths. This balance helps to reduce flank wear and sustain a reliable surface finish when machining stainless steel, particularly under varying feed and speed conditions. The PVD layer improves thermal and chemical resistance at the cutting edge, which translates into more stable tool life and fewer interruptions during batch production. Choosing a grade that emphasises both edge stability and economy supports higher uptime and predictable component quality.

Precision geometry that ensures secure mounting and easy indexing

The ISO DNMG150404 rhombic shape with a 55° wedge angle and 0° relief gives predictable cutting engagement and is widely supported by standard ISO holders. The insert’s double-sided design and cylindrical hole enable secure clamping and straightforward indexing to refresh the cutting edge, reducing changeover time. With a 0.4 mm corner radius and a plate thickness of 4.76 mm, the geometry is suited to controlled chip formation in external and internal turning tasks. Compatibility to the chosen holder is determined by form, relief angle, tolerance class, fastening and plate thickness—making this insert a pragmatic choice for customers seeking standardised, interchangeable tooling.

Productivity and economical machining in everyday production

Designed for turning operations, the insert offers stable chip control when paired with the appropriate double-sided chipbreaker and cutting parameters. The AH6225 grade is positioned as a universal solution for stainless steel, combining durability with reliable edge performance across batch sizes and mixed-series production. Selecting the right chipbreaker and optimising cutting data can shorten cycle times and reduce tooling costs per component, while the ISO-standard form supports rapid replacement and inventory rationalisation. Together, these aspects encourage process security and consistent surface quality in routine manufacturing.
