SNMG120408 AH6235 SNMG Turning Insert by Tungaloy — PVD-coated carbide, 0.8 mm radius

The SNMG120408 AH6235 is an ISO-format turning insert for external and internal turning, engineered for interrupted cuts and tough rostfrei applications where edge security and predictable wear are essential.

• PVD-coated carbide AH6235
• 0.8 mm corner radius for durable edge
• ISO SNMG120408 square insert
• Double-sided chipbreaker, cylindrical hole

Reliable edge security for demanding stainless-steel turning

The combination of a PVD-coated surface and the AH6235 carbide formulation provides enhanced resistance to wear and thermal loading, which is particularly important when machining stainless steel or other work-hardened alloys. The 0.8 mm corner radius increases the edge's mechanical strength and reduces susceptibility to micro‑fracture during interrupted cuts. This results in more consistent component quality and fewer unplanned tool changes, helping to maintain cycle times and reduce scrap rates. The coating also aids in adhesion resistance, extending tool life in high-temperature zones.

Designed for precise system integration and repeatable set-up

Compliance with the ISO SNMG120408 designation simplifies toolholder selection: geometry, relief angle, tolerance class, fastening method, size and thickness determine compatibility. The insert’s square form and cylindrical hole ensure secure clamping and repeatable positioning in a suitable external holder or boring bar. A correctly matched underlay and clamping set allow rapid indexing and consistent runout control, which supports predictable surface finish and dimensional accuracy. Clear reference to the system build—insert, holder, shim/clamp and replacement screws—reduces setup errors and supports efficient production workflows.

Optimise productivity through fewer interruptions and flexible application

The double-sided chipbreaker offers economical use of the cutting edges and enables multiple indexings before replacement, lowering per-part tooling costs. The tougher grade is tailored for operations with increased breakout risk and provides an advantage in unstable or interrupted machining conditions. Selecting the appropriate chipbreaker and grade relative to workpiece material and machining stability leads to measurable improvements in throughput and tool life. Where process stability allows, the insert’s geometry contributes to consistent chip control and better surface quality, supporting a reliable, cost‑efficient turning process.

FAQ

What materials is this insert suitable for?
The SNMG120408 AH6235 is formulated for stainless steel and similar tough alloys; the AH6235 grade and PVD-coated surface give improved resistance in demanding rostfrei machining.

Is the insert suitable for interrupted cuts?
Yes. The tougher AH6235 grade and a 0.8 mm corner radius make the insert appropriate for interrupted cutting where increased breakout risk occurs.

How is compatibility with a toolholder determined?
Compatibility depends on the insert’s form, relief angle, tolerance class, fastening, size and thickness; the ISO SNMG120408 designation helps to match a suitable external holder or boring bar for the insert.

Can the insert be indexed to present fresh cutting edges?
The insert design features a double-sided chipbreaker and a clamping hole, allowing multiple indexings to use fresh edges; consult the technical datasheet for the exact number of indexings for this SKU.
