DNMG150408 AH6225 Tungaloy indexable insert for turning — PVD-coated carbide, 55°

The DNMG150408 AH6225 is an ISO-standard rhombic indexable insert designed for external and internal turning, offering a sharp yet stable cutting edge optimised for stainless steels.

• ISO DNMG150408 geometry, 55° cutting angle
• PVD-coated AH6225 carbide for stainless steel
• Rhombic insert with 0.8 mm nose radius
• Double-sided chipbreaker, cylindrical hole

Stable chip control for reliable machining results

The PVD-coated grade AH6225 combines a fine, wear-resistant coating with a substrate that maintains a sharp edge under varying conditions. This results in improved chip control during medium turning operations on stainless steels, where built-up edge and variable workpiece properties can otherwise disrupt cycle times. The double-sided chipbreaker and rhombic form help to channel chips away from the cut, reducing interruptions and enabling consistent surface finish quality.

Seamless integration into ISO tooling systems

Built to the ISO-standard DNMG150408 form, the insert fits holders defined by geometry, relief angle and tolerance class; compatibility is determined by form, free angle, tolerance and fastening. The 55° approach and 0° relief angle suit conventional DNMG holders, while the cylindrical hole facilitates secure clamping. With a plate thickness of 4.76 mm and a 0.8 mm nose radius, the insert balances strength and detail, making it suitable for external and internal turning tasks requiring repeatable positioning and accurate dimension control.

Productivity and predictable tool life with reduced downtime

The reversible, double-sided design extends service life without compromising edge stability, supporting continuous production cycles and lower tool consumption. The PVD layer contributes to a durable cutting edge that withstands moderate cutting forces, which enhances process security and lowers the frequency of index changes. When paired with an appropriate holder and clamping set, this insert offers a practical route to improved throughput and reduced non-productive time in batch or single-part manufacturing.

FAQ

What materials is this insert suited for?
The DNMG150408 AH6225 insert is optimised for machining stainless steels and performs well where a stable cutting edge and good chip control are required.

How does the 0.8 mm nose radius affect the operation?
A 0.8 mm nose radius provides a compromise between edge strength and the ability to achieve fine feature detail; the DNMG150408 geometry with this radius supports reliable dimensional control and surface finish.

Is the insert compatible with standard DNMG holders?
Compatibility follows ISO DNMG rules; the insert form, relief angle and hole style match conventional DNMG holders when the holder and clamping set adhere to the same ISO tolerances.

Can both sides of the insert be used to extend life?
Yes, the insert is double-sided and reversible, which effectively doubles the available cutting edges and contributes to longer service intervals before replacement.

What benefits does the PVD coating bring to the cutting process?
The PVD-coated AH6225 grade offers improved wear resistance and edge stability under varying conditions, resulting in more predictable tool life and fewer process interruptions.
