CCMT 09T308 AH725 ISO turning insert, PVD‑coated carbide — Tungaloy

CCMT09T308 AH725 is an ISO‑standard rhombic turning insert designed for general turning applications on steels and stainless steels

• ISO‑standard rhombic insert
• PVD‑coated AH725 for steels and stainless steels
• 0.8 mm corner radius for robust edge
• 7° clearance angle for stable cutting

Reliable performance for mixed‑material production

The CCMT09T308 AH725 insert delivers consistent chip control and process security across a wide range of steels. The PVD‑coated carbide grade AH725 is engineered for universal use and resists premature edge breakdown when workpiece materials vary or when small tool sizes are required. In practice, this means fewer unexpected tool changes and a steadier production rhythm; the coating reduces abrasive wear while the substrate maintains toughness. The result is improved uptime and an economical balance between tool life and cutting performance.

Geometry that ensures repeatable accuracy

A well‑defined cutting geometry directly supports reproducible surface quality and tool life. The rhombic ISO form, with an included angle of 80° and a 0.8 mm corner radius, is suitable for both finishing and light roughing tasks, offering a compromise between strength and small‑radius profiling. The 7° clearance minimises rubbing and lowers cutting forces, while the plate thickness of 3.97 mm contributes to stable clamping. The insert’s hole is a cylindrical bore with a single‑side countersink (40°–60°), which assists secure seating in the pocket and straightforward indexability for fast replacement.

System compatibility and practical application advice

This insert functions as part of a complete ISO turning system: an indexable insert, a matching outer holder or boring bar, and the correct clamping set with replacement screws. Compatibility is determined by form, clearance, tolerance class, fixation and plate thickness, so selecting the correct holder geometry is essential for achieving the advertised performance. The one‑sided chipbreaker and universal AH725 grade are particularly suitable where frequent material changes occur or where process reliability is paramount. Typical uses include external and internal turning tasks on unalloyed and alloyed steels as well as stainless steels; choose the chipbreaker and grade to match the desired surface finish and stability.

Practical benefits for workshop productivity

Adopting this PVD‑coated indexable plate supports a predictable production workflow: fewer tool failures, consistent surface finishes and lower process variability. The universal nature of the grade minimises the number of different inserts required on the tool trolley, simplifying inventory and reducing setup time. For shops aiming to balance cost and uptime, this insert offers a pragmatic solution that prioritises process security, stable chip formation and dependable edge performance.
