DNMG 150412 AH905 indexable insert for ISO turning by Tungaloy — PVD‑coated carbide, rhombic form, 55° cutting angle

DNMG150412 AH905 Tungaloy indexable insert designed for ISO‑standard turning applications; compatible with matching holders and clamping systems.

• PVD‑coated carbide for high wear resistance
• Double‑sided chipbreaker for predictable chips
• ISO‑standard geometry for holder compatibility
• Rhombic form with cylindrical hole for secure clamping

Consistent cutting life through PVD‑enhanced carbide chemistry

The AH905 grade combines a hard PVD‑coating with a tough carbide substrate to resist flank wear and reduce the risk of edge chipping under varying cutting conditions. This chemistry supports a sharp cutting edge that preserves dimensional accuracy over multiple cuts, which translates into fewer indexings and less operator intervention. For users seeking process stability in general turning, the coating reduces adhesive wear and maintains surface finish quality without sacrificing tool life.

Geometry and clamping that protect the process

The insert’s ISO‑compliant geometry and rhombic form ensure compatibility with a broad range of external holders and boring bars; compatibility depends on form, relief angle, tolerance class, mounting and size. The 0° relief angle, 55° main cutting angle and 4.76 mm plate thickness create a stable seating and reduced vibration during machining. The cylindrical hole and the defined 1.2 mm corner radius help to position the insert precisely and allow secure clamping, which is essential for reproducible results in serial production.

Practical benefits: predictable chips and efficient reindexing

Equipped with a double‑sided chipbreaker, this insert delivers controlled chip formation and simplifies chip evacuation for turning operations. The reversible nature of the geometry allows rotation to fresh cutting edges, extending effective tool life and lowering consumable costs. The insert is supplied as part of a system that includes a matching external holder or boring bar, shim/clamping set and spare screws, enabling quick replacements on the shop floor and minimising downtime while maintaining process security.

FAQ

Is this insert compatible with standard ISO DNMG holders?
Yes. The DNMG150412 AH905 Tungaloy indexable insert follows ISO‑standard dimensions; compatibility with a holder is determined by form, relief angle, tolerance class, mounting, size and thickness.

Which machining tasks is this grade intended for?
The AH905 grade is a PVD‑coated carbide designed for turning operations where a sharp cutting edge and high process security are required; it is suited to continuous and interrupted cuts that demand wear resistance and chipping control.

How does the double‑sided chipbreaker benefit production?
The double‑sided chipbreaker on this Tungaloy insert promotes controlled chip formation and simplifies evacuation; the reversible geometry allows presenting fresh edges to extend service life and reduce tooling costs.

What does the DNMG150412 designation indicate?
The DNMG150412 code denotes the rhombic ISO insert form, nominal size and specific geometry; in this case, the 150412 variant includes the plate dimensions, hole style and a 1.2 mm corner radius suited for general turning.

Which components are needed to assemble a working tool system?
A complete turning system comprises the ISO insert, an appropriate external holder or boring bar, a shim or clamping set and the corresponding screws; the DNMG150412 AH905 Tungaloy insert is designed to integrate into this system for secure clamping and repeatable performance.
