DNMG150412 AH6225 Tungaloy turning insert — PVD-coated carbide, for turning applications

DNMG150412 AH6225 Tungaloy turning insert is an ISO-standard rhombic insert designed for external and internal turning, offering a 55° cutting geometry and a medium-duty grade optimised for rostfreier Stahl machining.

• DNMG150412 geometry, 55° cutting edge
• PVD-coated carbide AH6225 grade
• For rostfreier Stahl machining, versatile
• Double-sided insert, cylindrical hole

Consistent wear resistance and predictable performance

The PVD-coated finish on this carbide grade provides a hard, wear-resistant surface that reduces flank wear and extends tool life under varying conditions. The AH6225 composition is developed as a universal grade for rostfreier Stahl, combining a sharp cutting edge with sufficient toughness for interrupted cuts and changing feeds. For production environments, this means fewer insert changes, improved process stability and a consistent surface finish — clear advantages when repeatability and uptime are priorities.

Geometry and dimensions that support precise turning

Configured in the standard DNMG shape, the insert features a 55° approach angle and a rhombic form that permit both external and limited internal turning operations. Its physical dimensions — 15 mm inscribed circle and 4.76 mm thickness — together with a 1.2 mm corner radius influence both edge strength and the achievable surface finish. The insert is double-sided with a cylindrical hole, enabling economical indexable use; compatibility with clamping systems depends on holder form, relief angle and tolerance class. These measurable parameters help planners select a matching holder and clamping set for reliable assembly and repeatable results.

Practical benefits for process reliability and machining quality

Selecting the correct chipbreaker and the AH6225 grade yields controlled chip formation and improved machining stability for rostfreier Stahl components. A medium-duty profile such as this supports a balance between productivity and tool life, particularly in mixed-production environments where feed rates and workpiece stability vary. Clear advantages include consistent edge geometry for predictable tool changes and the ability to maintain surface integrity without excessive cutting forces — supporting higher throughput with fewer interruptions.

FAQ

Which materials is this insert suited for?
The DNMG150412 AH6225 Tungaloy turning insert is optimised for rostfreier Stahl and performs well in a range of alloyed steels when matched with the appropriate chipbreaker and cutting data.

What are the key dimensions to consider when selecting a holder?
Key dimensions are the 15 mm inscribed circle, 4.76 mm thickness and 55° cutting geometry; ensure the holder matches these values and the insert’s hole style for secure clamping.

How does the AH6225 grade behave under variable cutting conditions?
AH6225 combines a sharp yet stable edge with a PVD coating to deliver predictable wear behaviour and good performance in medium-duty turning, especially when conditions change between passes.

Is the insert reversible and economical?
Yes, the insert is double-sided with a cylindrical hole, allowing indexable usage and improved economy by offering two cutting edges per side where applicable.

What role does the 1.2 mm corner radius play?
A 1.2 mm corner radius increases edge strength and helps produce a stable surface finish on rostfreier Stahl while moderating cutting forces for improved tool life.
