SNMG120412 AH110 Tungaloy ISO turning insert — PVD‑coated carbide, square 12 mm

A SNMG120412 AH110 Tungaloy ISO‑normed square insert engineered for dependable external and internal turning where a sharp cutting edge and process security are required

• PVD-coated carbide for wear resistance
• Double-sided chipbreaker for stability
• ISO‑standard 12 mm square form
• 1.2 mm corner radius for versatile turning

Consistent turning performance that reduces downtime

The PVD‑coated AH110 grade combines a wear‑resistant surface with a tough carbide substrate to maintain a sharp cutting edge under varying machining conditions. This insert supports steady metal removal rates and reduces unscheduled tool changes, contributing to improved machine uptime. The double‑sided chipbreaker promotes controlled chip formation, which minimises interruptions for chip clearing and helps preserve tool life. Such measurable process stability is particularly valuable in batch production and mixed‑lot environments.

Easy integration and predictable geometry for holder compatibility

Designed to the ISO insert system, the square format with a 12 mm side and standard centre hole ensures compatibility with a wide range of external holders and boring bars. The 0° rake angle and standard tolerance class mean repeatable clamping and predictable cutting directions, simplifying setup and reducing trial runs. The 4.76 mm plate thickness and cylindrical hole offer mechanical rigidity in the clamping assembly, so the insert performs reliably even when axial and radial forces fluctuate during external and internal turning operations.

Material and coating explained for informed tool selection

The combination of a PVD coating and a carbide substrate in the AH110 grade is optimised for wear resistance and edge integrity. PVD (physical vapour deposition) provides a hard, thin coating that reduces flank and crater wear while preserving a sharp edge for finishing and semi‑finishing passes. The 1.2 mm corner radius balances edge strength with the ability to produce fine surface finishes; a larger radius increases edge stability, while a smaller radius favours very fine detail. Selecting this grade and geometry suits workshops seeking a reliable, general‑purpose solution for a range of steels and common alloys.

FAQ

What materials is this insert suited for?
The SNMG120412 AH110 Tungaloy insert is intended for a broad range of steels and common alloys; the PVD coating and carbide substrate give wear resistance suitable for general turning tasks.

How does the double‑sided chipbreaker affect machining?
A double‑sided chipbreaker on this insert promotes controlled chip formation and stability, reducing machine interruptions and supporting more consistent cycle times with the SNMG120412 AH110 grade.

Can the insert be used for both external and internal turning?
Yes — the ISO square form, centre hole and standard geometry make the insert suitable for both external and internal turning when combined with the appropriate holder or boring bar.

What does the 1.2 mm corner radius mean for surface finish?
A 1.2 mm radius offers a compromise between edge strength and surface quality: it improves edge durability while still allowing good surface finishes in semi‑finishing and finishing passes.

Is the insert compatible with standard ISO holders?
The SNMG‑format and ISO designation ensure compatibility with holders and clamping sets designed for SNMG inserts, subject to matching form, size and tolerance class
