CCMT060204 AH725 Tungaloy indexable insert — PVD‑coated carbide, 0.4 mm radius

The CCMT060204 AH725 is an ISO‑standard rhombic turning indexable insert designed for external and internal turning, featuring a single‑sided chipbreaker and a cylindrical hole with one‑side countersink for secure clamping.

• ISO rhombic turning insert CCMT format
• PVD-coated carbide grade AH725
• 0.4 mm corner radius for fine finishing
• Cylindrical hole with 40°–60° countersink

Stable cutting performance for mixed steels

The AH725 grade delivers consistent cutting behaviour across a wide range of steels and stainless steels, offering a balanced combination of wear resistance and edge stability. The PVD coating reduces friction and protects the substrate under interrupted cuts, while the carbide substrate provides the toughness required for small tools and demanding process conditions. This results in fewer insert changes and a more predictable tool life, supporting uninterrupted production runs and improved process security.

Secure clamping and ISO compatibility for fast changeovers

Thanks to the ISO CCMT060204 designation and the central cylindrical hole with one‑side countersink (40°–60°), the insert installs reliably in matched holders and boring bars. The standardised geometry simplifies inventory and replacement procedures: a compatible outer holder, shim/clamp set and replacement screws form a complete system. The 0.4 mm corner radius and 7° clearance angle contribute to stable contact and repeatable seating, reducing setup time and the risk of misalignment.

Geometry and chip control explained

The rhombic form with an 80° included angle provides a versatile approach angle for both roughing and finishing passes. The single‑sided chipbreaker is tuned for controlled chip formation on a variety of steels, improving evacuation and reducing the chance of built‑up edge. For operators unfamiliar with insert geometry: the chipbreaker influences where the chip curls and breaks, so choosing this single‑sided design helps maintain surface quality and protects the cutting edge under variable feed rates.

Economy and recommended use cases

Using this PVD‑coated carbide insert in mixed‑material batches pays off through extended edge life and reduced downtime. The grade is particularly advantageous for shops facing frequent material changes or operating smaller tooling setups where process reliability is paramount. Typical applications include external finishing, light to medium roughing and internal turning where dimensional stability and surface integrity are required.

FAQ

What materials is this insert suited for?
The CCMT060204 AH725 insert is specified for a broad spectrum of steels and stainless steels, offering fracture resistance and stable cutting across mixed workloads.

How does the AH725 grade improve process security?
AH725’s PVD coating and carbide substrate combine to reduce friction and resist edge damage, giving the insert predictable wear behaviour and elevated process reliability in turning applications.

Which holders fit the CCMT060204 format?
ISO‑standard CCMT holders and compatible boring bars that accept size 06 rhombic inserts with a centrally located cylindrical hole and countersink will accommodate this insert.

What cutting tasks suit the 0.4 mm corner radius?
A 0.4 mm corner radius is ideal for fine finishing and light to medium turning passes where surface quality and dimensional control are priorities.

Is this insert suitable for interrupted cuts or unstable setups?
Yes; the fracture‑resistant AH725 grade and PVD coating improve performance on interrupted cuts, and the insert’s geometry supports stability in less rigid conditions.
