DNMG150412 AH6225 Tungaloy turning insert — ISO rhombic insert for turning (55°)

The DNMG150412 AH6225 Tungaloy is an ISO rhombic turning insert engineered for reliable external and internal turning, optimised for machining stainless steels under medium cutting conditions

• DNMG ISO rhombic insert 55°
• PVD‑coated carbide AH6225 for stainless steels
• 1.2 mm corner radius for a robust cutting edge
• Double‑sided chipbreaker, with cylindrical hole

Consistent performance with PVD‑coated carbide for stainless steels

The combination of a PVD‑coated carbide substrate and the AH6225 grade delivers a balance of sharpness and edge stability that is particularly effective for stainless steels and similar difficult‑to‑cut alloys. This balance reduces flank wear during interrupted or variable cutting conditions and improves surface finish in medium machining. The insert’s chemistry and coating are chosen to extend tool life without sacrificing cutting ability, which translates directly into fewer tool changes and more predictable cycle times on production turning applications.

Stable geometry for repeatable turning results

The rhombic 55° shape with a 1.2 mm corner radius provides a dependable compromise between strength and form accuracy: the geometry supports controlled chip flow while the double‑sided chipbreaker ensures improved chip control across a range of feeds. The presence of a cylindrical central hole secures positive clamping and ensures repeatable positioning, so process stability and reproducibility are enhanced. These features together reduce vibration and help maintain a consistent cutting edge, benefiting both throughput and dimensional accuracy.

Easy integration into ISO holder systems and operational benefits

Designed as an ISO‑standard turning insert, this indexable plate fits established holder ecosystems when the form, clearance, tolerance class, fastening method, size and thickness match. A 0° clearance angle and a plate thickness of 4.76 mm are typical parameters to verify when selecting the mating toolholder and clamping set. The insert is double‑sided, enabling economical use of the cutting edges and straightforward replacement workflows. Clear compatibility criteria and the modular system setup—insert, suitable external holder or boring bar, shim/clamping set and spare screws—reduce downtime and simplify inventory management for production shops.

FAQ

What materials is this insert optimised for? The DNMG150412 AH6225 Tungaloy insert is optimised primarily for stainless steels and alloys with similar machining behaviour, offering improved edge life and surface quality in medium turning operations.

How does the geometry affect machining outcomes? The 55° rhombic form and 1.2 mm corner radius support a robust cutting edge that reduces vibration and improves dimensional repeatability, while the double‑sided chipbreaker enhances chip control across varying feeds.

Which holder characteristics must be checked for compatibility? Compatibility requires matching the insert form, clearance angle (0°), tolerance class, fastening type, size (15 mm) and thickness (4.76 mm) with the chosen holder, shim and clamping set to ensure secure seating and repeatable positioning.

Is the coating relevant for tool life and performance? Yes, the PVD coating on the AH6225 grade improves wear resistance and helps maintain a sharp yet stable cutting edge under the medium machining conditions typical for stainless steels.
