CPMT 090304 AH725 — ISO indexable turning insert, 0.4 mm radius by Tungaloy

A CPMT090304 AH725 indexable insert engineered for ISO-compliant external and internal turning, offering a universal, outchip-resistant PVD-coated carbide grade optimised for steel and stainless steels

• ISO-compliant rhombic insert, 09 size
• PVD-coated AH725 grade for steels
• 0.4 mm corner radius for fine finishes
• Compatible with cylindrical hole clamping

Increased process security for mixed-material turning

The PVD-coated AH725 carbide grade delivers a balanced combination of toughness and wear resistance, making it suitable for a wide range of steels and stainless steels. This universality reduces the need for frequent insert changes when workpiece materials vary, improving uptime and consistent cycle times. The grade is designed to maintain stable chip formation and minimise unexpected edge breakouts, supporting predictable production results and lowered scrap rates.

Geometry that improves surface quality and edge life

With a 0.4 mm corner radius and an 11° relief angle, the rhombic geometry provides a compromise between cutting-edge strength and the ability to achieve fine surface finishes on finishing passes. The rhombic form and 3.18 mm thickness supply sufficient support for interrupted cuts while the modest corner radius helps avoid excessive tool engagement at low feeds, which benefits both dimensional accuracy and tool life. These geometric features translate directly into fewer rework cycles and more consistent part quality.

System compatibility for straightforward tool changes

The insert follows the ISO specification and features a cylindrical hole with a single-sided countersink (40°–60°), ensuring compatibility with common holders and clamping systems. Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness; selecting the correct holder and clamp reduces setup time and secures a repeatable clamping position. The insert’s design supports quick indexing and replacement, which helps to keep machines running and reduces non-productive time during tool changes.

Practical advantages for turning operations and productivity

Intended for both external and internal turning, the insert’s one-sided chipbreaker is matched to applications where controlled chip formation and process stability are priorities. For small tools or operations with varying materials, the AH725 grade offers a reliable balance of edge robustness and wear resistance, often extending the interval between tool changes. The result is a measurable improvement in machining throughput and a reduction in downtime related to tooling, contributing to overall cost-efficiency in component production.
