DNMG150412 AH6225 Tungaloy turning insert — PVD-coated carbide, 55° rhombic for turning

The DNMG150412 AH6225 is an ISO rhombic turning insert engineered for medium machining and variable conditions, providing a balanced cutting edge and reliable repeatability in workshop and production environments.

• PVD-coated carbide for extended life
• Universal grade for rostfreier Stahl
• Double-sided chipbreaker for economy
• ISO rhombic form, 15 mm, 55° geometry

Consistent cutting performance and material compatibility

The insert uses a PVD-coated carbide substrate in the AH6225 grade, designed specifically as a universal solution for rostfreier Stahl. The coating enhances edge stability and wear resistance, while the substrate maintains toughness under interrupted cuts. This combination yields a sharp yet stable cutting edge, reducing the need for frequent indexing and helping to maintain cycle times. For production planners, this means fewer tool changes and more predictable output during medium-duty turning.

Precise fit and quick indexable exchange to reduce downtime

Produced to ISO dimensions, the rhombic plate ensures consistent seating and repeatable clamping, with the holder compatibility determined by form, clearance, tolerance class, fastening and thickness. The insert features a cylindrical hole and a 0° clearance angle that allow secure fixation in compatible external holders or boring bars. Standardised geometry simplifies tool management across toolrooms and enables faster changeovers, contributing to steady process performance and reduced set-up times.

Improved surface quality and cost efficiency in serial machining

The double-sided chipbreaker design provides economical usage through reversible indexing, while the 1.2 mm corner radius strikes a balance between strength and surface finish. The 55° lead angle supports a stable cutting action that helps to deliver consistent finishes on workpieces. Taken together, these attributes support both part quality and tool cost control: fewer inserts consumed per shaft of production and less rework due to improved initial surface characteristics.

FAQ

Is this insert suitable for rostfreier Stahl?
Yes. The AH6225 grade is specified as a universal grade for rostfreier Stahl and is engineered to provide a stable cutting edge under varied stainless machining conditions.

How is the insert secured in the holder?
The insert has a cylindrical hole and is seated to ISO dimensions; compatibility depends on form, clearance angle, tolerance class, fastening and thickness for correct clamping.

Can both sides of the insert be used?
Yes. The DNMG150412 AH6225 is double-sided with a chipbreaker on both faces, allowing reversal and economical use of the cutting edges.

What are the typical applications for this insert?
The plate is intended for external and internal turning operations in general workshop and production settings, especially for medium machining where a balance between edge sharpness and stability is required.

What does the 1.2 mm corner radius mean for finishing?
A 1.2 mm radius offers a compromise between strength and surface finish: it supports robust cutting forces while still delivering acceptable surface quality for many turning tasks.
