CPMT09T308 AH725 ISO turning insert for turning operations — Tungaloy

The CPMT09T308 AH725 is an ISO-format turning insert designed for external and internal turning, offering a single-sided chipbreaker and a cylindrical hole with a one-side countersink for secure clamping.

• PVD-coated cemented carbide AH725
• Universal grade for steel and stainless steels
• 0.8 mm corner radius for controlled cuts
• Cylindrical hole with single-side countersink

Consistent chip control from a dedicated grade

The combination of a PVD-coated surface and the AH725 cemented carbide grade provides steady cutting behaviour and improved wear resistance. The coating reduces built-up edge tendency and promotes reliable chip control, which is particularly beneficial when machining mixed batches of alloyed steel and stainless steels. This quality leads to fewer interruptions for insert changes and supports stable cycle times on production runs.

Geometry and clamping engineered for compatibility

The ISO-format geometry with an included angle of 80° and an 11° clearance angle ensures broad compatibility with standard holders; the insert’s rhombic form and the cylindrical hole with a single-side countersink facilitate straightforward, repeatable clamping. These design choices reduce setup variability and allow for quick insertion into established tool systems, supporting efficient changeovers and maintaining concentricity during turning.

Edge integrity and predictable performance for turning

A 0.8 mm corner radius provides a balance between cutting edge strength and surface finish, making the insert suitable for finishing and light to moderate semi-finishing passes. The single-sided chipbreaker is matched to the grade to control chip formation at a variety of cutting conditions, so the user benefits from predictable forces and a lowered risk of insert chipping under intermittent cuts or variable material hardness.

Practical application guidance and handling notes

The insert is intended for general-purpose turning where process reliability is a priority; the universal AH725 grade is appropriate when batches include both steels and stainless steels or when tool inventory should be minimised. For best results, select a matching holder that respects the insert’s form, tolerance class and thickness (3.97 mm), and set cutting data in accordance with the machine rigidity and workpiece material to exploit the grade’s strength in productive metal removal.
