CCMT 09T308 AH6225 ISO turning insert — rhombic CCMT, 80° included angle, Tungaloy

CCMT09T308 AH6225 is an ISO‑standard rhombic turning insert designed for external and internal turning; the insert combines a PVD-coated carbide grade for reliable edge stability with a single‑sided chipbreaker for controlled chips under varying conditions.

• PVD-coated carbide AH6225
• Optimised for stainless steel turning
• Rhombic CCMT shape, 80° cutting angle
• Single-sided chipbreaker, sharp stable edge

Reliable edge geometry for consistent machining results

The combination of AH6225 grade and a PVD-coated surface provides a balance between edge sharpness and robustness, which is particularly valuable when machining stainless steel. The coating enhances resistance to built-up edge and heat, while the carbide substrate maintains dimensional stability during typical medium‑duty turning. This results in fewer interruptions for insert changes and a more predictable tool life, supporting higher uptime and process reliability on the shop floor.

ISO compatibility and straightforward holder selection

Produced to ISO specifications in the CCMT format, the insert ensures compatibility with most standard CCMT holders when matching form, relief angle and tolerance. The geometry features an 80° included angle and a 7° relief angle, with a plate thickness of 3.97 mm and a 0.8 mm corner radius; the mounting uses a cylindrical hole with a one‑sided countersink (40°–60°). These standardised dimensions simplify holder choice and tool assembly, reducing setup time and the risk of mismatched fixtures.

Improved chip control and surface quality

The one‑sided chipbreaker is designed for effective chip control in both external and internal turning operations, producing predictable chip flow that reduces the likelihood of surface damage. The sharp yet stable cutting edge contributes to a clean finish at typical cutting parameters for mid‑range turning. Overall, the insert helps to shorten cycle times and maintain consistent workpiece quality, which benefits production runs and subcontract machining where repeatability is crucial.

Suitable applications and selection advice

Intended primarily for turning applications, the insert is best applied where material conditions vary and operators need a universal grade for dependable performance. The PVD-coated AH6225 is particularly suited to stainless steel, delivering stable cutting behaviour under variable feeds and speeds. For optimal results, select the chipbreaker and specific holder combination according to workpiece stability and the desired surface finish; this measured approach minimises tool wear and supports efficient material removal.
