CCMT120412 AH725 Tungaloy turning insert — PVD‑coated carbide, 1.2 mm radius

A CCMT120412 AH725 Tungaloy turning insert engineered for ISO‑standard external and internal turning, offering a universal, fracture‑resistant grade optimised for steel and stainless steels.

• PVD‑coated carbide AH725
• Universal grade for steel and stainless steels
• 1.2 mm corner radius for secure edges
• ISO‑standard CCMT120412 form

Reliable cutting performance for mixed-production environments

The insert delivers consistent chip control and predictable durability thanks to the PVD‑coated carbide composition and the AH725 grade, which is formulated as a universal, breakout‑resistant option for machining steel and stainless steels. With a 1.2 mm corner radius the geometry balances edge strength and surface quality, making the component suitable for smaller toolholders and operations requiring high process security. The ISO conformity of the plate ensures that fitment is determined by form, clearance, tolerance class, fastening, size and thickness, so replacement and inventory management in mixed fleets remain straightforward.

Consistent surface quality with extended tool life

The hard, wear‑resistant coating reduces flank wear and improves resistance to built‑up edge, which translates into longer service intervals and more reliable production runs. The rhombic form and the single‑sided chipbreaker create a positive cutting engagement that supports stable cutting forces and a good surface finish on both roughing and finishing passes. The modest 7° clearance helps maintain the correct cutting geometry while limiting radial intrusion; in practice this combination reduces vibration and improves repeatability across batches.

Plug‑and‑play integration into ISO turning toolkits

Designed for easy integration into standard ISO holders, the insert features a 12 mm size, 4.76 mm thickness and a central hole with a cylindrical bore plus a single‑side countersink (40°–60°) for secure clamping. The 80° lead angle provides a versatile approach for both external and internal turning tasks. When selecting the appropriate chipbreaker and holder, consider the workpiece material and required stability — the CCMT120412 AH725 excels where process reliability and broad material coverage are priorities, particularly in applications with frequent material changes.

FAQ

What materials is this insert suitable for?
The CCMT120412 AH725 insert is specified for steel and stainless steels, the AH725 grade giving universal, breakout‑resistant performance across these materials.

Which toolholders fit this insert?
Compatibility is determined by the ISO CCMT form: holders matching the plate form, clearance, tolerance class, fastening, size 12 and thickness 4.76 mm are suitable for secure clamping.

Is the insert intended for roughing or finishing?
With a 1.2 mm corner radius and single‑sided chipbreaker, the insert supports both finishing and general‑purpose turning; selection of chipbreaker and cutting parameters will refine performance for roughing or fine finishing.

How does the PVD coating benefit production?
The PVD coating on the AH725 grade reduces wear and built‑up edge, improving tool life and process stability in varied production runs.

Does the insert include a central hole for clamping?
Yes — the plate features a cylindrical hole with a one‑side countersink (40°–60°) to ensure reliable clamping in compatible toolholders.
