DNMG 150412 AH6225 DNMG ISO 150412 indexable turning insert – Tungaloy

DNMG150412 AH6225 is a rhombic ISO indexable turning insert designed for external and internal turning in rostfreier Stahl and similar materials

• ISO rhombic insert, 55° cutting geometry
• PVD-coated carbide for rostfreier Stahl
• Double-sided chipbreaker for stable cutting
• Cylindrical hole, secure fastening

Secure ISO fit and straightforward holder compatibility

The insert follows the ISO-Drehwendeschneidplatten standard, which ensures predictable fitment to compatible holders. Compatibility depends on form, relief angle, tolerance class, fastening type, size and thickness; this standardisation minimises setup time and reduces the risk of mismatched tool assemblies. The rhombic geometry at 55° provides a reliable compromise between strength and reach, while the cylindrical hole ensures consistent clamping repeatability. For machining lines that require quick changeovers, the standard format simplifies inventory and supports predictable process windows.

Consistent cutting performance in rostfreier Stahl

The AH6225 grade is a PVD-coated carbide developed for universal performance in rostfreier Stahl, offering a sharp yet stable cutting edge for medium-duty and varying conditions. The combination of coating and substrate delivers enhanced wear resistance and edge security under changing feeds and speeds, which helps maintain surface finish and dimensional control. The double-sided chipbreaker assists chip control without compromising edge integrity, reducing the frequency of stoppages for chip management and enhancing overall throughput.

Practical system setup and handling benefits

A complete machining system consists of the ISO insert, a matching external holder or boring bar, a support shim or clamp set and replacement screws. The 4.76 mm plate thickness contributes to stiffness in the cutting zone, while the 1.2 mm corner radius smooths engagement and spreads cutting forces across the edge, extending tool life under interrupted cuts. The insert’s reversible nature halves tooling cost per edge compared with single-sided solutions, enabling a cost-effective balance between life-cycle expense and cutting performance.

Productivity advantages and application guidance

Designed for both external and internal turning, the insert performs best when the chipbreaker and grade are selected to match workpiece stability, feed and depth of cut. The ISO rhombic shape offers versatility across turning tasks, and the PVD coating helps maintain edge condition in sticky or work-hardening rostfreier Stahl. When combined with a stable machine setup and suitable feeds, the insert contributes to predictable cycle times and consistent surface quality, supporting high first-pass yields and lower rework rates.

FAQ

What materials is this insert designed for?
The AH6225 grade of the DNMG150412 insert is formulated primarily for rostfreier Stahl and comparable alloys, providing a balance of edge sharpness and wear resistance suitable for medium machining operations.

How does the 1.2 mm corner radius affect cutting?
A 1.2 mm corner radius on the insert distributes cutting forces more evenly, improving edge life and surface finish when turning rostfreier Stahl, while also offering better resistance to minor interruptions.

Is the insert reversible and what is the benefit?
Yes, the plate is double-sided; reversing the insert provides an additional cutting edge, effectively reducing tooling cost per usable edge and extending runtime before replacement is required.

Which holder characteristics must be matched to ensure compatibility?
Compatibility requires matching form, relief angle, tolerance class, fastening type, size and thickness to the ISO insert; the cylindrical hole style and plate dimensions should align with the chosen clamping system for repeatable secure mounting.

Can this insert be used for internal boring as well as external turning?
The insert’s rhombic geometry and chipbreaker make it suitable for both external and internal operations, provided the selected holder offers the necessary rigidity and access for the intended internal geometry.
