CCMT 120404 AH6235 – Turning Insert by Tungaloy (ISO CCMT, PVD-carbide)

The CCMT120404 AH6235 is an ISO-form turning insert designed for external and internal turning, optimised for interrupted cuts and machining of stainless steels.

• PVD-coated carbide grade AH6235
• Rhombic CCMT 80° geometry
• 0.4 mm corner radius for fine finishing
• Single-sided chipbreaker with centre hole

Durable grade for challenging stainless-steel operations

The PVD-coated AH6235 carbide composition provides a balance of toughness and wear resistance that is particularly suited to machining stainless steel and other materials prone to work-hardening. The coating enhances flank wear resistance and thermal stability, while the substrate hardness maintains edge strength during interrupted cuts. As a result, the insert supports longer tool life and steadier process windows, which reduces unplanned stops and improves overall throughput in production environments.

Geometry and clamping ensure repeatable accuracy

The rhombic CCMT form with an 80° approach angle, combined with a 0.4 mm corner radius and a 7° clearance, delivers a predictable cutting force vector and an even engagement at the tool tip. The insert’s centre hole (cylindrical with a single-sided countersink at 40°–60°) enables secure seating and consistent repeatability when used with compatible holders. The plate thickness of 4.76 mm and nominal size 12 mm contribute to radial stability and edge support, resulting in improved surface finish and fewer vibrations during external and internal turning.

Practical productivity advantages on the shop floor

Equipped with a single-sided chipbreaker, this insert promotes controlled chip formation and evacuation for medium to heavy interrupted feeds. The combination of the PVD surface and the robust substrate reduces edge chipping and extends usable life, delivering a clear cost-in-use benefit where frequent tool changes otherwise disrupt production. Compatibility with ISO-standard holders simplifies inventory management; selecting the correct holder, clamp and screw ensures stable performance and repeatable setups across batch runs.

FAQ

What materials is this insert best suited for?
The CCMT120404 AH6235 insert is optimised for stainless steel and workpieces where interrupted cuts or increased breakout risk occur, thanks to the AH6235 PVD-coated carbide grade.

Which holder types are compatible with this insert?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; use ISO-compatible holders designed for CCMT inserts and the specified 80° geometry for correct seating.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert controls chip formation and evacuation, improving surface quality and reducing the chance of re-cutting chips during longer or interrupted cuts.

Is the insert suitable for internal turning as well as external turning?
Yes, the insert’s rhombic CCMT form and defined geometry make it suitable for both external and internal turning tasks when used with the correct boring bars or holder assemblies.

What information should be provided when ordering a replacement?
Please quote the designation CCMT120404 AH6235, article number 6903445 or manufacturer SKU TUN6903445 to ensure correct identification.
