DNMG 150404 AH6225 — Turning insert by Tungaloy with PVD-coated grade for stainless steels

The DNMG150404 AH6225 Tungaloy insert is an ISO rhombic turning insert designed for external and internal turning of stainless steels and similar materials

• ISO rhombic insert DNMG 150404 for turning
• PVD-coated AH6225 carbide for stainless steels
• Sharp, stable cutting edge for medium machining

Consistent edge life from a PVD-coated universal grade

The AH6225 grade is a PVD-coated carbide developed for reliable performance when machining stainless steels under varying conditions. Its balance between hardness and toughness produces a sharp cutting edge that resists chipping during interrupted cuts while still providing good wear resistance for medium cutting parameters. This combination reduces the frequency of index changes and supports predictable tool life, which helps to plan production cycles with fewer disruptions.

Geometry that ensures repeatable accuracy and secure clamping

The rhombic geometry with a 55° included angle and a 0.4 mm corner radius combines freedom for approach angles with edge robustness for finishing and semi-finishing operations. The insert’s ISO designation ensures compatibility with standard external holders when form, tolerance, relief angle and thickness are matched. Clear geometry translates into consistent surface finish and repeatable dimensional results, particularly important where process stability and interchangeability matter.

Economical double-sided use and practical handling

The insert is double-sided, allowing efficient use of both cutting edges before replacement, which lowers tooling cost per cutting edge. The central cylindrical hole and standard mounting form facilitate straightforward seating and clamping in common toolholders; spare screws and wedge sets typical for ISO systems complete the setup. The 4.76 mm thickness adds rigidity in clamping, reducing vibration risk and supporting higher achievable feeds without compromising dimensional control.

Application guidance and material match for turning tasks

Engineered for turning, the insert performs well in external and internal operations where a mix of moderate cutting speeds and intermittent conditions occur. Its PVD-coated carbide substrate is suitable for stainless steels and similar alloys; for highly abrasive or unusually hard workpieces, select grades and chipbreakers matched to the specific condition. When integrating into an existing toolline, verify holder compatibility with the ISO 150404 geometry, relief angle and tolerance class to ensure secure seating and correct rake behaviour.

FAQ

What materials is this insert suitable for?
The answer: The AH6225 grade on the DNMG150404 insert is optimised for stainless steels and offers a compromise of edge sharpness and wear resistance for common turning tasks.

Can the insert be used on both external and internal turning operations?
Yes. The ISO rhombic form and the cylindrical hole allow the insert to be clamped in compatible external holders and boring bars for internal turning when the holder matches the ISO 150404 geometry.

How many usable edges does this insert provide?
This is a double-sided insert, offering two primary cutting edges per index; flipping and indexing extend the usable life before replacement.

What should be checked to ensure holder compatibility?
Verify holder form, relief angle, tolerance class, fastening method, size and plate thickness (4.76 mm); correct matching guarantees secure clamping and intended cutting geometry.

Is the product available with a chipbreaker suited for heavy depths of cut?
The insert is supplied with a double-sided chipbreaker tailored for medium machining; for heavy depths or high-volume removal, select a chipbreaker and grade matched to the specific machining strategy.
