CPMT080208 AH6225 ISO turning insert (80° rhombic) by Tungaloy

The CPMT080208 AH6225 is an ISO-standard rhombic turning insert for external and internal turning, designed for medium cutting and optimised for rostfreier Stahl machining.

• PVD-coated carbide grade AH6225
• 80° rhombic geometry for stable engagement
• 0.8 mm corner radius for controlled chip formation
• Single-sided chipbreaker with centred hole

Precision and consistent results for turning operations

This insert combines a PVD coating with a wear-resistant carbide substrate, delivering a balance between edge sharpness and stability that suits interrupted cuts and varying conditions. The AH6225 grade is formulated for universal use on rostfreier Stahl, offering reliable edge life during medium machining. The 0.8 mm corner radius reduces peak load while maintaining cutting stability, which helps to produce repeatable part tolerances and reduces the risk of premature edge failure. The result is process stability and fewer tool changes in serial production.

Controlled chip formation and edge protection explained

The single-sided chipbreaker on this insert promotes predictable chip control for shoulder and profile turning, reducing the likelihood of long, entangling chips. A chipbreaker shapes the fracture and flow of chips at the cutting zone; in practice this improves surface finish and reduces machine downtime for chip clearance. The insert’s PVD layer supports a sharp cutting edge that resists built-up edge formation under varying feeds and speeds, and the rhombic 80° geometry provides a secure seat in the holder for stable cutting forces.

Compatibility, mounting and system benefits

Compatibility with ISO holders is determined by insert form, clearance angle, tolerance class, fixing method, size and thickness; the CPMT080208 AH6225 is supplied with a centring hole and 40°–60° single-sided countersink to ensure repeatable clamping. The plate thickness of 2.38 mm and the standard 08 size fit common external holders and boring bars designed for ISO-indexable plates. Selecting the correct holder and clamp set ensures the insert’s performance is translated into consistent component quality and predictable tool life.

Why this grade suits rostfreier Stahl and variable conditions

The AH6225 composition is optimised for rostfreier Stahl, combining toughness with wear resistance to handle adhesive tendencies and work hardening commonly encountered with these alloys. In applications with moderate depths of cut and interrupted cuts, the insert’s combination of PVD coating, edge geometry and chip control reduces process risk and supports higher uptime. For shops focused on repeatability and low set-up effort, this insert represents a pragmatic choice between edge life and surface integrity.

FAQ

What materials is this insert intended for?
The CPMT080208 AH6225 insert is intended primarily for rostfreier Stahl and similar alloys where a balance of edge sharpness and toughness is required.

How is the insert clamped in the holder?
The insert features a centring hole and a single-sided countersink (40°–60°) to ensure secure, repeatable clamping in ISO-compatible holders for the CPMT080208 AH6225.

What does the 0.8 mm corner radius affect in practice?
A 0.8 mm corner radius provides a compromise between cutting-edge strength and the ability to achieve good surface finish; for the AH6225 grade this helps maintain stability during medium cutting.

Can this insert handle interrupted cuts?
Yes, the combination of a robust carbide substrate and the AH6225 PVD coating gives the insert resilience for interrupted cuts and variable machining conditions.

Which holder type is recommended for best results?
Use an ISO-standard external holder or boring bar sized for the 08 plate, combined with a suitable shim and clamp set, to achieve the intended performance of the CPMT080208 AH6225.
