CCMT 09T304 AH6225 – CCMT turning insert for Drehen by Tungaloy (0.4 mm radius, PVD-coated)

A CCMT 09T304 AH6225 indexable insert designed for turning (Drehen), offering a balanced combination of edge sharpness and robustness for medium cutting regimes

• PVD-coated carbide grade AH6225
• Optimised for rostfreier Stahl
• Rhombic CCMT geometry with 7° relief
• 0.4 mm corner radius for precise finishing

Predictable performance for rostfreier Stahl and mixed conditions

The PVD-coated AH6225 carbide grade is specified for universal use on rostfreier Stahl, providing a compromise between sharpness and wear resistance that supports consistent cycle times. The coating reduces adhesion and improves thermal resistance during interrupted cuts or variable feeds, which results in fewer unplanned tool changes and more stable component tolerances. For production environments where material batches or cutting conditions vary, this configuration reduces setup risk and maintains surface quality across runs.

Geometry tuned for accuracy and repeatability

The rhombic CCMT form with an included angle of 80° and the 0.4 mm corner radius is intended to combine robustness with the ability to achieve fine surface finishes. The moderate radius allows controlled cutting edge engagement for facing and light turning while preserving edge strength at the outer corner. The 7° relief contributes to predictable chip flow and reduces rubbing, which helps sustain dimensional accuracy over repeated tool indexes and simplifies process parameter setting on conventional and CNC lathes.

Coating and substrate engineered for tool life

A PVD-coated carbide substrate offers a hard, wear-resistant surface that tolerates elevated temperatures and abrasive contact commonly encountered with rostfreier Stahl. The AH6225 composition is engineered to provide stable chip formation and extended useful life under medium-duty operations, lowering regrind frequency and improving cost per part in moderate runs. Explaining technical terms: PVD (physical vapour deposition) is a thin, adherent layer that enhances hardness and reduces chemical affinity between the workpiece and the tool surface.

System compatibility and practical handling

The insert is supplied in the ISO CCMT form (ISO designation CCMT09T304) and is compatible with standard CCMT external holders and boring bars when matching the insert form, relief angle, tolerance class, fixing method, size and thickness. The version with a cylindrical hole and single-sided countersink (40°–60°) enables secure clamping and easy indexing. Its nominal thickness of 3.97 mm and size designation 09 follow ISO conventions, allowing straightforward integration into existing tool inventories and assuring interchangeability for both external and internal turning tasks.

FAQ

What materials is this insert best suited for?
The CCMT09T304 AH6225 Tungaloy indexable insert is optimised for rostfreier Stahl and performs well across a broad range of steels in medium cutting regimes.

Can this insert be used for internal as well as external turning?
Yes, the CCMT geometry and the design features of the insert permit both external and internal turning when mounted in the appropriate holder.

What does AH6225 indicate for the insert?
AH6225 denotes the PVD-coated carbide grade chosen for a balance of sharpness and wear resistance suitable for variable cutting conditions and reliable chip formation.

How does the 0.4 mm corner radius influence finishing?
A 0.4 mm corner radius provides a compromise between edge strength and surface finish capability, allowing fine finishing without excessively weakening the corner during interrupted cuts.

Is the CCMT09T304 compatible with standard ISO CCMT holders?
The insert follows the ISO CCMT form; compatibility depends on match of form, relief angle, tolerance class, fixing and thickness, and it is typically compatible with standard CCMT external holders and boring bars.
