DNMG150608 AH6225 Tungaloy turning insert for turning

A DNMG150608 AH6225 turning insert designed for stable medium turning operations, optimised for rostfreier Stahl and variable machining conditions

• ISO DNMG rhombic insert, 55° cutting angle
• PVD-coated carbide grade AH6225 for rostfreier Stahl
• Double-sided chipbreaker for reversible use
• 0.8 mm corner radius for medium finishing

Consistent edge life and predictable machining results

The insert delivers a balanced combination of a PVD-coated carbide substrate and a geometry tuned for consistent performance. The AH6225 grade is crafted to maintain a sharp yet robust cutting edge under changing cutting conditions, which reduces the need for frequent index changes and supports continuous production. Predictable wear behaviour enables stable component tolerances and lowers total machining costs through fewer tool replacements and less downtime.

Effective chip control and surface quality for rostfreier Stahl

With a double-sided chipbreaker and ISO-compliant geometry, the geometry assists in controlled chip formation and evacuation during external and internal turning. The chipbreaker, matched to the grade and cutting conditions, improves surface finish and minimises secondary operations. When machining rostfreier Stahl, the combination of edge stability and chip control reduces built-up edge and heat concentration, helping to achieve reliable component quality in one pass.

Compatibility, handling and economic benefits

The insert conforms to ISO DNMG dimensions and its fit is governed by form, clearance angle, tolerance class, fixation, size and thickness. The rhombic insert with a cylindrical hole is reversible and compatible with standard DNMG holders and boring bars; this reversible use doubles the effective cutting edges per insert. Reduced tool inventory and simpler re-grading of inserts lead to faster tool changeovers and improved shop-floor efficiency, supporting short lead times in batch production.

Coating and substrate explained for practical decisions

The tool uses a PVD-coated wear-resistant surface applied to a fine-grain carbide substrate, chosen for a broad material range with emphasis on rostfreier Stahl. The coating enhances thermal and abrasive resistance while the substrate provides toughness for medium cutting depths. The 0.8 mm corner radius offers a compromise between edge strength and surface finish; it is suited for finishing to medium-depth turning where rigidity and repeatable geometry are important.

FAQ

What materials is this insert best suited for?
The DNMG150608 AH6225 insert from Tungaloy is formulated for rostfreier Stahl and provides balanced performance across ferritic and austenitic stainless steels.

Can the insert be used on both external and internal turning applications?
Yes, the ISO DNMG geometry enables use in external and internal turning when paired with a suitable holder and correct mounting tolerance.

How does the AH6225 grade affect tool life?
The AH6225 PVD-coated grade offers a compromise between edge sharpness and stability, extending usable life in medium cutting when machining rostfreier Stahl.

Is the insert reversible and how many cutting edges are available?
The rhombic DNMG insert is double-sided and reversible, providing multiple cutting edges per insert to reduce tooling costs.

What corner radius is recommended for medium finishing?
This insert has a 0.8 mm corner radius, which is intended to balance edge strength with surface finish for finishing to medium operations.
