DNMG 150612 AH6225 Tungaloy turning insert (ISO DNMG150612, 55°)

DNMG150612 AH6225 Tungaloy turning insert crafted for general-purpose turning in demanding materials

• Versatile PVD-coated carbide grade AH6225
• Universal performance for stainless steels
• Rhombic shape with 55° lead angle
• 6.35 mm thickness for stable clamping

Consistent edge life through a balanced grade

The PVD-coated carbide substrate of this insert combines wear resistance with a deliberately sharp yet stable cutting edge, making it suitable for medium cutting depths and varying process conditions. The AH6225 grade is formulated to manage the tough machining behaviour of stainless steels, promoting a consistent chip formation that reduces edge chipping and unplanned tool changes. The coating enhances adhesive wear resistance and heat protection, which translates into longer in-process life and more predictable tool cycles, supporting higher uptime on production lines.

ISO form and dimensions that simplify tool setup

Built to the ISO DNMG specification, the rhombic geometry with a 55° approach and a plate thickness of 6.35 mm ensures compatibility with common holders when the form, relief angle, tolerance class, fastening method, size and thickness match. The insert’s rhombic outline and cylindrical hole facilitate repeatable clamping and a secure fit, which reduces vibration and improves surface finish on workpieces. Clear, standardised dimensions support quick changeovers and minimise setup errors in mixed production environments.

Reliable chip control and economical use in turning

Equipped with a double-sided chipbreaker, the insert permits economical use of both cutting edges and supports steady chip evacuation during external and internal turning operations. The corner radius 1.2 mm strengthens the cutting edge for interrupted cuts and provides a robust profile for common turning tasks, striking a balance between edge strength and profile accuracy. As part of a system—insert plus compatible holder, shim and clamping set—the component is designed to deliver repeatable results when the correct chipbreaker and grade are selected for workpiece material and machine stability.

FAQ

Which materials is this insert suitable for?
The AH6225 grade is designed as a universal solution for stainless steels and performs reliably across a broad range of austenitic and other chromium-containing alloys.

How does the AH6225 grade help in everyday production?
AH6225 combines a PVD coating with a carbide substrate to reduce adhesive wear and maintain a sharp cutting edge, improving consistency and lowering unplanned tool changes in medium machining.

Will this insert fit existing DNMG holders?
Compatibility depends on holder form, relief angle, tolerance class, fastening and size; the DNMG150612 designation and 6.35 mm thickness match common DNMG holders when those parameters align.

What is the advantage of the double-sided chipbreaker?
A double-sided chipbreaker offers economical edge usage and reliable chip control, enabling longer usage before indexation and stable machining behaviour.

What does the corner radius mean for machining results?
The corner radius 1.2 mm increases edge strength for interrupted cuts and contributes to a controlled tool mark on the workpiece while retaining sufficient profile for finishing passes.
