CCMT 09T308 AH725 turning insert — Tungaloy

The CCMT 09T308 AH725 is an ISO rhombic turning insert designed for versatile external and internal turning applications where process reliability and resistance to chipping are required.

Universal PVD-coated AH725 grade for mixed steels
Rhombic CCMT shape with 80° included angle
0.8 mm corner radius for controlled chip formation
Cylindrical hole with single-side countersink for secure clamping

High-performance grade for mixed steels and stainless steels

The PVD-coated AH725 grade offers a balance of toughness and wear resistance that suits changing workpiece materials. For turning of both plain steel and stainless steel, the combination of the PVD-coated carbide substrate and the optimised microstructure reduces the risk of edge chipping and premature wear. This results in more consistent tool life across batches and less unplanned downtime, which supports predictable production planning and lower overall machining costs.

Geometry engineered to stabilise the cutting process

The rhombic insert geometry with an 80° included angle and a 0.8 mm corner radius promotes stable cutting forces and a repeatable cut profile. The single-sided chipbreaker design improves chip control in interrupted cuts and varying depths of cut, while the 7° relief angle helps reduce rubbing and heat generation at the flank. Together these features lead to improved surface finish and reduced rework, especially beneficial when switching between roughing and finishing passes.

Clear compatibility and easy integration into existing tool systems

The insert conforms to ISO dimensions and the CCMT format, making it compatible with common external holders and boring bars when form, relief angle, tolerance class, fastening method, size and thickness match. The central cylindrical hole with a single-side countersink (40°–60°) secures the insert reliably in the pocket and simplifies index changes. For operations that demand quick set-ups and reproducible clamping, this insert supports efficient tool management and minimises bench time.

Practical benefits for process security and productivity

Choosing the CCMT 09T308 in AH725 provides predictable performance in variable production environments. The grade is particularly appropriate for smaller tool sizes and applications where process security is critical: shorter trial phases, consistent batch-to-batch results and stable chip formation reduce scrap rates and support higher machine utilisation. Where mixed-material runs or frequent material changes occur, the insert’s universal character reduces the need for multiple specialised grades.

FAQ

What materials is this insert suitable for?
The CCMT 09T308 AH725 insert is designed for general turning and is especially suitable for steel and stainless steel applications due to the toughness and wear resistance of the AH725 grade.

How does the 0.8 mm corner radius affect the cut?
A 0.8 mm corner radius gives a balance between edge strength and surface finish: it reduces the likelihood of chipping while delivering a good machined surface for both roughing and light finishing passes.

Is the insert compatible with standard CCMT holders?
Yes, the insert follows ISO CCMT dimensions; compatibility depends on matching form, relief angle, tolerance class, fastening and thickness to the holder.

What advantages does the PVD coating bring?
The PVD-coated surface enhances wear resistance and adhesion strength, improving performance under varying cutting speeds and delivering consistent tool life across mixed-material batches.

Which article number and SKU should be ordered for replacement?
Use article number 6864924 or SKU 6864924-Tungaloy when ordering the CCMT09T308 AH725 turning insert from Metav Werkzeuge.
