CPMT 080208 AH725 Tungaloy indexable insert — PVD-coated carbide for turning, 0.8 mm corner radius

The CPMT080208 is an ISO‑normed indexable turning insert for external and internal turning, offering a universal, breakout‑resistant PVD‑coated carbide grade for mixed‑material production environments.

• ISO‑normed insert for turning operations
• PVD‑coated carbide grade AH725
• 0.8 mm corner radius, single‑sided chipbreaker
• Rhombic form with central hole and countersink

Consistent machining performance for steel and stainless steels

The PVD‑coated carbide grade AH725 delivers a balanced combination of wear resistance and toughness, designed specifically for mixed‑material runs. As a result, the insert ensures stable chip formation and reduced risk of edge breakouts when turning stainless steels and various grades of steel. This balance translates into fewer interruptions for tool changes and a steadier production rhythm, which is particularly beneficial for small‑tool setups and operations where process reliability is essential.

Clear compatibility and system setup for rapid integration

Compatibility with toolholders is determined by geometric and tolerance factors: insert form, relief angle, tolerance class, clamping method, size and thickness. The rhombic geometry and 80° included angle suit a broad range of holders and boring bars, while the central hole with cylindrical seat plus a single‑side countersink facilitates secure fastening. When assembled as a system — insert, suitable external holder or boring bar, shim/clamping set and replacement screws — the result is a robust, repeatable mounting that supports stable cutting conditions and predictable component quality.

Simple chip control and application suitability

The single‑sided chipbreaker and the 0.8 mm corner radius are optimised for conventional turning tasks where moderate to demanding process security is required. The chipbreaker assists in breaking and evacuating chips reliably, reducing the likelihood of rework and improving surface finish consistency. For operations that alternate between different workpiece materials, this insert provides an economical and productive option without frequent grade swaps.

FAQ

Which materials is this insert suitable for?
The CPMT080208 AH725 Tungaloy indexable insert is optimised for machining steel and stainless steels, offering breakout resistance and reliable performance across changing workpiece materials.

How is holder compatibility assured?
Compatibility depends on form, relief angle, tolerance class, clamping type, size and thickness; the rhombic CPMT shape and the specified dimensions allow selection of matching holders and boring bars for secure mounting.

What chip control can be expected?
The single‑sided chipbreaker provides dependable chip segmentation and evacuation, helping to maintain surface quality and reduce the need for secondary operations when using the AH725 grade.

Can the insert be used for both external and internal turning?
Yes — the geometry and hole design make the insert suitable for external turning and for use in boring bars for internal turning, provided the correct holder and clamping parts are used.

What identifiers should be referenced when ordering or specifying the insert?
Use the article number 6864988 or the manufacturer SKU TUN6864988 to ensure the correct CPMT080208 AH725 Tungaloy indexable insert is supplied.
