CPMT060204 AH725 Tungaloy indexable insert — ISO indexable turning insert, PVD-coated carbide

CPMT060204 AH725 is an ISO-standard indexable insert for turning, designed for reliable external and internal operations with universal, break-resistant performance.

• AH725 PVD-coated carbide grade
• ISO 06 size, 80° rhombic geometry
• Single-sided chipbreaker with cylindrical hole

Consistent process security with PVD-coated AH725 grade

The insert combines a PVD-coated surface with a robust carbide substrate, delivering improved wear resistance and edge stability in cyclic production. The AH725 grade is formulated as a universal, fracture-resistant option for applications that alternate between steel and rostfreier Stahl, ensuring fewer interruptions due to edge failure. The coating reduces flank and crater wear, which translates into longer tool life and a lower rate of insert changes—benefits that support higher machine utilisation and predictable output in batch or lights-out machining environments.

Geometry and ISO compatibility for flexible clamping solutions

With its 80° rhombic form and ISO 06 designation, the insert fits a wide range of standard external and internal holders. The configuration and compatibility depend on form, clearance angle, tolerance class, clamping method, size and thickness; the insert’s 11° clearance and 0.4 mm radius contribute to a balanced cutting edge for mixed turning tasks. The 0.4 mm radius helps absorb minor vibration and improves finish on medium- to roughing passes, while the rhombic geometry enables effective approach angles for both longitudinal and profiling cuts. Clear specification of these parameters simplifies holder selection and reduces setup time.

Application range and chip control for predictable surface results

The single-sided chipbreaker is tuned for general turning and supports controlled chip formation across varying cut depths and feed rates. This promotes stable cutting when machining steel and rostfreier Stahl, particularly in smaller tool assemblies or where process reliability is a priority. The insert’s PVD surface and geometry help maintain an even cutting action, which improves surface integrity and reduces the need for secondary finishing. As a result, productivity rises through fewer interruptions and more consistent part quality.

System integration, handling and economical operation

The insert is supplied as part of an ISO insert system comprising the indexable plate, the appropriate external holder or boring bar, a shim/clamping kit and replacement screws. The plate thickness of 2.38 mm and its cylindrical hole with a single-sided countersink (40°–60°) ensure secure fixation and straightforward indexing during service. Such mechanical clarity reduces changeover errors and simplifies inventory management. The robust combination of grade and geometry yields a cost-effective solution for shops seeking repeatable performance without frequent regrinding or excessive tooling variety.
