CPMT090304 AH725 – CPMT turning insert (ISO) by Tungaloy

CPMT090304 AH725 is an ISO‑standard rhombic insert for external and internal turning, providing an 11° clearance and a single‑sided chipbreaker for dependable performance on steel and stainless steels

• Universal AH725 grade for steel and stainless steels
• PVD-coated carbide for stable edge life
• Rhombic ISO insert, 11° clearance, 0.4 mm radius
• Central hole with cylindrical seat and countersink

Reliable edge life and consistent chip control for mixed workshops

The PVD-coated AH725 grade combines a wear‑resistant coating with a tough carbide substrate to deliver a balance between tool life and fracture resistance. The result is stable chip formation across a broad range of steels and stainless steels, which reduces the risk of unexpected insert failure in mixed‑material production. For small‑diameter tools or applications with high demands on process security, this combination helps maintain cutting edge integrity and consistent component quality. The coating also improves resistance to built‑up edge and oxidation at elevated cutting temperatures.

Seamless integration into ISO toolholder systems for fast changeovers

Designed as an ISO‑standard rhombic insert, the geometry and mounting features ensure straightforward compatibility with matching external holders and boring bars. Key locating parameters—form, clearance angle, tolerance class, fastening method, size and thickness—determine holder fit; the CPMT090304 uses an 11° clearance and a 0.4 mm corner radius to suit a variety of finishing and medium‑cut turning tasks. The central cylindrical hole with a one‑sided countersink provides positive seating and repeatable clamping, simplifying insert indexing and reducing setup time in multi‑station operations.

Improved productivity and surface finish with focused application choice

When the correct chipbreaker and grade are selected to match the workpiece and cutting conditions, this insert contributes to higher productivity and better surface quality. The single‑sided chipbreaker is optimised for controlled swarf flow in common turning operations, which can lower the need for secondary finishing. Selecting the AH725 grade for intermittent or mixed‑material work supports lengthened intervals between insert changes, thereby decreasing machine downtime and total cutting cost per part. For complex requirements, Metav Werkzeuge can advise on the ideal chipbreaker and cutting parameters to maximise output.
