DNMG 150616 AH6225 Turning indexable insert by Tungaloy — PVD-coated carbide, 1.6 mm radius

A DNMG150616 AH6225 rhombic indexable insert designed for external and internal turning, optimised for stainless steels and variable machining conditions.

• DNMG150616 rhombic 55° insert
• PVD-coated AH6225 grade for stainless steels
• 1.6 mm corner radius for stable cutting edges
• Double-sided chipbreaker, cylindrical hole

High-performance grade for reliable stainless steel turning

The PVD-coated AH6225 grade combines a sharp, wear-resistant cutting edge with enough toughness for medium cutting depths, offering consistent results across variable conditions. The PVD-coated surface reduces built-up edge and improves wear behaviour, which translates into longer in-process lifetime and fewer index changes. For shops seeking predictable tool life and reduced downtime, this grade balances edge stability and economical material removal. The composition and coating are chosen to manage the specific challenges of machining stainless steels, where heat and adhesion can shorten tool life if the wrong grade is used.

Geometry and chip control that protect productivity

A rhombic geometry with a 55° included angle and a 1.6 mm corner radius gives a secure cutting profile that resists chipping while maintaining good surface finish on the workpiece. The double-sided chipbreaker is engineered to segment and evacuate chips efficiently, helping to prevent entanglement and to keep cycle times low. The insert’s cylindrical hole and standard dimensions ensure correct clamping and repeatable positioning in ISO-compliant toolholders, reducing set-up errors. In practice, the geometry and chip control reduce rework and contribute to stable process windows for both roughing and finishing passes.

System compatibility and easy specification for production planning

Designed to ISO standards, this indexable insert fits common external holders and boring bars when matched for form, clearance angle, tolerance class, fastening method, size and thickness. The standardised format simplifies inventory management and tool selection across machines. The carbide substrate and moderate thickness provide rigidity during interrupted cuts and versatile performance across alloys. For engineers planning production runs, the insert’s predictability supports cost-effective batch machining and easier machining parameter standardisation, aiding process security and quality control.

FAQ

What materials is this insert suited for?
The DNMG150616 AH6225 insert is formulated for machining stainless steels; the PVD-coated AH6225 grade provides improved wear resistance and adhesion control specifically for such alloys.

How many usable edges does the insert provide?
This rhombic DNMG insert is double-sided, offering multiple cutting edges per index, which extends the service life before the insert needs replacement.

What does AH6225 mean in practical terms?
AH6225 denotes a PVD-coated carbide grade tuned for a balance of sharpness and toughness; it is intended for medium-depth cuts on stainless steels and variable machining conditions.

Is the insert compatible with standard ISO holders?
Yes; the insert follows ISO dimensions and locates via its cylindrical hole and standard thickness, but holder compatibility depends on matching form, clearance, tolerance class, fastening and size.

How does the chipbreaker benefit the process?
The double-sided chipbreaker fragments and directs chips away from the cut, reducing the risk of entanglement, improving surface finish and maintaining stable cutting forces.
