CPMT090302 AH725 ISO turning insert — PVD-coated carbide for turning, by Tungaloy

The CPMT090302 AH725 is an ISO rhombic turning insert designed for reliable external and internal turning; its compact geometry and universal grade make it suitable for mixed-material production where process security is critical.

• ISO rhombic insert CPMT090302
• PVD-coated AH725 universal carbide grade
• 0.2 mm corner radius for accurate finish
• Cylindrical hole + single countersink 40°–60°

Consistent cutting performance and reduced process risk

The PVD-coated AH725 grade is formulated as a universal, fracture-resistant option for machining steel and rostfreier Stahl, providing stable chip formation and predictable wear characteristics. A PVD-coated carbide substrate reduces adhesive wear and extends edge life under variable conditions, which translates into fewer tool changes and more predictable batch times. The small 0.2 mm corner radius supports fine profiling and improved surface finish on light to medium cuts, while the 11° relief angle ensures reliable engagement and reduced rubbing. These technical choices prioritise reproducibility and economical productivity in component turning.

Designed for fast system integration and secure clamping

The insert follows ISO dimensions and is compatible with holders when matched by form, relief, tolerance class, fastening, size and thickness, which simplifies stocking and tool management. The cylindrical hole with a single countersink 40°–60° enables firm location and consistent clamping torque in standard indexable holders; the system approach—insert, holder, underlay/shim and fixing screw—reduces set-up time and minimises downtime during index changes. Clear adherence to ISO geometry helps maintain repeatable clamping and dimensional stability across multiple machines and operators.

Versatile application range with a focus on process security

Engineered for both external and internal turning, the single‑sided chipbreaker and AH725 composition provide a balance between edge robustness and general-purpose performance. This combination is particularly advantageous when workshops face varying workpiece materials or smaller tool assemblies that demand high process security. The insert’s rhombic form (09) and 3.18 mm thickness allow compact toolholders to deliver consistent cutting forces, while the universal grade supports long runs with fewer quality deviations. For operations seeking a dependable, multi‑purpose turning solution, this insert offers a pragmatic compromise between precision and tool life.

FAQ

What holders are compatible with this insert?
Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness; the CPMT090302 AH725 fits holders designed for 09-size ISO rhombic inserts with 3.18 mm thickness and a cylindrical hole with a single countersink (40°–60°).

Which materials can be machined with this grade?
The AH725 grade on the CPMT090302 insert is a universal, fracture‑resistant option intended for machining steel and rostfreier Stahl, making it suitable for mixed‑material workshops and changing workpiece conditions.

What benefit does the PVD coating provide?
The PVD coating on this carbide insert reduces adhesive wear, improves edge strength under variable cutting conditions and contributes to more consistent tool life for the Tungaloy turning insert.

Is the insert suitable for internal turning?
Yes, the insert is designed for both external and internal turning operations; the rhombic form and compact radius support precise profiling in confined tool geometries.

How is the insert secured in the holder?
The insert is located by the cylindrical hole and clamped using the single countersink (40°–60°) arrangement; a matching underlay/shim and fixing screw complete the standard ISO system.
