DNMG150412 AH6225 DNMG turning insert (PVD-coated carbide, 55°) — Tungaloy

The DNMG150412 AH6225 is an ISO-standard turning insert for external and internal turning, optimised for stainless steels and fluctuating cutting conditions.

• ISO-standard 55° rhombic geometry
• PVD-coated carbide for stainless steels
• 1.2 mm nose radius for stable finishes
• Double-sided chipbreaker with hole

High reliability through optimised coating and substrate

The combination of a PVD-coated carbide substrate and the AH6225 grade delivers a balance between sharpness and edge stability that is particularly suited to medium-duty turning operations. The coating reduces built-up edge formation when machining stainless steels, while the base carbide maintains a predictable wear progression; this means longer tool life and fewer unplanned insert changes, which supports a steady production flow and improved process economics.

Precision geometry for consistent surface quality

A 55° geometry in a rhombic format provides versatile clearance and approach angles for both contouring and facing operations. The 1.2 mm nose radius is a compromise between strength and surface finish, enabling reliable dimensional control with reduced vibration risk. When paired with a correctly specified holder, the insert’s design translates into repeatable part quality and reduced rework rates on rotating components.

Practical compatibility and efficient handling

The insert is furnished with a cylindrical hole and double-sided chipbreaker, permitting two indexable cutting edges per side and straightforward clamping in standard ISO holders. Compatibility is determined by form, relief angle, tolerance class, clamping method, size and thickness; selecting the matching external holder or boring bar completes the system for immediate use in turning operations. The robust edge preparation of the AH6225 grade supports varied cutting parameters, helping to maintain cycle time and surface integrity under changing conditions.
