DNMG150416 AH6225 Tungaloy turning insert — PVD‑coated carbide, 55° rhombic

A DNMG150416 AH6225 insert for turning, designed as an ISO‑standard rhombic insert for stainless steel machining and medium‑duty operations

• PVD‑coated carbide for durable cutting
• Optimised for stainless steel machining
• 55° rhombic form with 1.6 mm radius
• Double‑sided chipbreaker, ISO‑compatible

Higher productivity through a sharper, more stable cutting edge

The PVD‑coated carbide grade AH6225 combines a fine, wear‑resistant coating with a substrate engineered for moderate cutting forces; this yields a sharp cutting edge that remains stable under variable conditions typical for stainless steel. The coating reduces built‑up edge and abrasion while the substrate controls flank wear, so chip formation stays predictable and cycle times remain consistent. For shops seeking process reliability, the result is fewer tool changes and more consistent component quality.

Seamless integration into ISO turning systems

As an ISO‑standard rhombic insert, the DNMG150416 format fits a wide range of external holders and boring bars when matched by form, free angle, tolerance class, fastening and thickness. The 0° clearance angle and cylindrical hole permit secure screw mounting and straightforward indexing; the double‑sided design offers economical re‑use of both edges. This compatibility simplifies inventory management and allows rapid replacement during production, keeping set‑up times minimal and throughput high.

Practical handling and application advantages for daily machining

The 15 mm inscribed size, 1.6 mm corner radius and 4.76 mm thickness provide a robust profile for medium‑duty turning where repeatable surface finish and tool life matter. The double‑sided chipbreaker supports controlled chip evacuation in stainless steels, reducing the risk of workpiece damage and improving operator safety. For workshops facing mixed batches, the universal nature of the grade reduces the need for multiple specialised inserts while delivering consistent results across changing conditions.

FAQ

Which materials is this insert suited to?
The DNMG150416 AH6225 Tungaloy turning insert is a universal grade optimised primarily for stainless steel; its PVD coating and substrate balance wear resistance and edge stability for common stainless machining tasks.

What are the critical dimensions to check for holder compatibility?
Check the inscribed circle/size (15 mm), insert thickness (4.76 mm), corner radius (1.6 mm) and the 55° approach angle; the cylindrical hole must match the clamping screw and seat of the chosen holder.

Is the insert reversible and how is it mounted?
The insert is double‑sided and indexable; mounting uses the cylindrical hole with a suitable screw and seat in ISO‑compatible holders, allowing the second cutting edge to be used after rotation.

What does the AH6225 grade and PVD coating deliver in practice?
AH6225 with a PVD layer provides improved resistance to adhesive wear and better control of chip formation on stainless steels, extending usable edge life and supporting consistent surface quality.
