SNMG120412 AH6235 – ISO turning insert by Tungaloy for turning, 90° square, 1.2 mm radius

The SNMG120412 AH6235 Tungaloy ISO turning insert is engineered for external and internal turning, offering a PVD-coated carbide grade tailored to rostfreier Stahl and interrupted cutting conditions.

• PVD-coated carbide AH6235
• Optimised for rostfreier Stahl
• Suitable for interrupted cuts
• 90° square geometry, 1.2 mm radius
• Double-sided with cylindrical hole

Longer tool life and secure machining of stainless materials

The PVD-coated carbides of the AH6235 grade combine toughness and surface hardness to resist chipping under demanding conditions. This makes the insert especially suitable for machining rostfreier Stahl and applications with frequent interruptions in the cut, where brittle grades would fail prematurely. The coating improves resistance to built-up edge and wear, while the tougher substrate reduces catastrophic edge fracture, delivering more reliable tool life and fewer unscheduled tool changes.

Geometry and system compatibility that support process stability

A true benefit of the square, 90° geometry with a 1.2 mm corner radius is increased rigidity at the cutting edge and a predictable engagement with the workpiece. ISO compatibility depends on the insert shape, clearance angle, tolerance class, fixing method, size and thickness; therefore the insert integrates into standard turning systems when the matching holder, underlay/shim and clamping screw are used. Clear specification of these parameters enables consistent setup and repeatable component quality on turning centres and lathes.

Flexible handling and economical indexability

The double-sided design with a cylindrical hole and a robust chipbreaker allows two repositions per insert, lowering unit tooling cost and simplifying inventory. The doppelseitig chipbreaker layout provides balanced cutting conditions on both sides and supports reliable chip control in many turning scenarios. Because the insert is part of an ISO system, replacement is straightforward: a secure clamping arrangement and standard spare screws permit fast changeovers and minimal downtime.

Practical application guidance for stable results

Designed for external and internal turning tasks, the insert performs best when the chipbreaker and grade are matched to the workpiece material, cutting mode and machine stability. For operations on rostfreier Stahl or components with interrupted cuts, the AH6235 grade offers enhanced resistance to edge breakage; for smoother finishing passes a smaller feed and appropriate coolant strategy improve surface quality. The machining system typically comprises the ISO turning insert, a compatible holder, an underlay and the clamping set to ensure positional accuracy and repeatable performance.

FAQ

What is the primary application of this insert?
The SNMG120412 AH6235 insert is intended for external and internal turning, with a focus on rostfreier Stahl and interrupted cutting where a tougher grade reduces edge breakage.

How does the AH6235 grade differ from standard grades?
AH6235 is a tougher, PVD-coated carbide grade developed to improve resistance to chipping in difficult-to-cut materials and interrupted operations, offering longer in-process life for Tungaloy turning inserts.

Can the insert be indexed to use both cutting edges?
Yes, the SNMG120412 is double-sided and designed for indexability; the cylindrical hole and secure clamping enable safe repositioning to use multiple edges.

Which holder features are required for correct compatibility?
Compatibility depends on the holder’s form, clearance (frewinkel), tolerance class, fixing method, size and thickness; using a matching ISO external holder, underlay and clamping screws ensures correct seating and repeatable results.

Is this insert suitable for finishing passes on rostfreier Stahl?
The AH6235 grade can be used for finishing, but optimised feed, cutting speed and coolant strategy help achieve the desired surface quality while preserving edge integrity.
