CPMT 090308 AH725 Tungaloy indexable insert for turning, PVD-coated carbide

A CPMT 090308 AH725 Tungaloy indexable insert designed for ISO-standard external and internal turning, offering a fracture-resistant grade and stable clamping for mixed-steel machining.

• ISO-standard rhombic insert 09 size
• PVD-coated carbide AH725 for steels
• One-sided chipbreaker for secure cutting
• Countersunk centre hole for stable clamping

Reliable performance for mixed-steel production

The AH725 PVD-coated carbide grade delivers a balanced combination of wear resistance and toughness, making it suitable for machining steel and stainless steel under varying conditions. The universal, fracture-resistant composition reduces the risk of unexpected edge breakouts when changing workpiece materials or switching to smaller tooling setups. This translates into fewer tool changes, less unplanned downtime and more consistent cycle times—advantages that directly support production efficiency and process reliability.

Geometry and clamping that ensure repeatable results

Designed as a rhombic 09 insert with an included angle of 80°, this indexable plate provides predictable cutting engagement and good access in confined turning and boring situations. The 0.8 mm corner radius and 11° clearance angle contribute to robust edge strength and stable cutting forces, while the 3.18 mm thickness and the cylindrical centre hole with a single-side countersink (40°–60°) enable stable clamping and repeatable positional accuracy. Compatibility with holders depends on form, clearance, tolerance class, fastening, size and thickness, so choosing the correct seat and clamping kit maintains surface finish and dimensional stability.

Practical selection and system integration for turning operations

For efficient integration into the tooling system, match the one-sided chipbreaker and the AH725 grade to the workpiece material and machining stability. Typical use cases include external roughing and finishing as well as internal turning when tool overhang and rigidity are controlled. The ISO-standard system comprises the indexable insert, a compatible turning holder or boring bar, a seating pad/clamping kit and replacement screws—together these elements ensure secure fastening and consistent chip control. The CPMT 090308 AH725 insert offers a pragmatic balance between tool life and process security, supporting predictable production outputs.

FAQ

What materials is this insert suitable for? The CPMT 090308 AH725 insert is specified for machining steel and stainless steel; the AH725 grade offers a balance of wear resistance and fracture toughness for mixed-material batches.

How does the insert ensure secure clamping in the holder? A cylindrical centre hole with a single-side countersink (40°–60°) and a plate thickness of 3.18 mm provide stable seating and repeatable clamping, maintaining the insert position under cutting loads.

Which operations are typical for this insert? Typical applications include external and internal turning where a rhombic 09 geometry and an 80° included angle provide access and consistent chip formation for finishing and light roughing.

What role does the AH725 coating play? The PVD AH725 coating improves wear resistance while retaining toughness, reducing the likelihood of edge chipping and supporting consistent tool life across varying steels.

How should the chipbreaker be matched to the process? Select the one-sided chipbreaker based on workpiece material, depth of cut and rigidity of the setup; this insert’s chipformer is designed to stabilise chip flow and enhance process security.
