CPMT 09T308 AH6225 — ISO turning insert by Tungaloy for medium turning of rostfreiem Stahl

CPMT09T308 AH6225 is an ISO-format rhombic turning insert designed for external and internal turning; the PVD-coated carbide grade provides a balance of sharpness and edge stability across variable machining conditions.

• ISO-standard rhombic insert CPMT09T308
• PVD-coated carbide AH6225 for rostfreiem Stahl
• 11° relief angle for stable cutting
• Cylindrical hole with countersink for secure clamping

Consistent mid-range performance for rostfreiem Stahl

The PVD-coated carbide grade AH6225 is formulated for universal performance when machining rostfreiem Stahl, delivering a sharp cutting edge that withstands fluctuating conditions during medium cuts. The single-sided chipbreaker promotes controlled chip formation, reducing interruption and supporting higher process reliability. For production environments where consistent surface finish and repeatable tool life matter, this insert offers an effective compromise between aggressiveness and durability, helping to maintain throughput without excessive tool changes.

ISO compatibility and secure mounting for stable results

Designed as part of the ISO turning insert family, suitability to a specific holder depends on the insert’s form, relief angle, tolerance class, fixing method, size and thickness. The rhombic geometry and the cylindrical hole with a single-sided countersink (40°–60°) enable secure clamping in standard ISO holders and boring bars; the 11° relief angle and 3.97 mm thickness contribute to mechanical stability during radial and axial cutting forces. Clear labelling of ISO designation and dimensional data simplifies tool selection and helps avoid mismatches that can affect runout and surface integrity.

Process security through coating and geometry

The combination of a robust PVD layer and the insert’s 0.8 mm corner radius provides an extended cutting edge life under varying feeds and depths of cut. The PVD coating reduces flank wear and improves thermal resistance, which is particularly beneficial when turning rostfreiem Stahl where work hardening and adhesive wear can be issues. Choosing the correct chipbreaker and grade for the cut and machine rigidity allows the tool to deliver repeatable part quality, aiding predictable tool-change intervals and lower overall machining costs while maintaining productivity.

FAQ

Which holder types are compatible with this insert?
Compatibility is determined by the ISO form and the insert’s dimensions; the CPMT09T308 AH6225 fits standard ISO rhombic holders and boring bars that accept a size 09 insert with a cylindrical hole and countersink.

Is this grade suitable for finishing or roughing operations?
The AH6225 grade is optimised for medium machining of rostfreiem Stahl, offering a balance between sharpness and wear resistance rather than extreme finishing or heavy roughing specialisation.

What clamping hardware is required?
A matching ISO external holder or boring bar with the appropriate clamp or screw that engages the cylindrical hole and countersink will secure the insert; ensure the holder’s tolerance class and form match the insert specification.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert promotes predictable chip formation during turning, which improves evacuation and reduces the risk of built-up edge, supporting a steadier process and surface finish.

What key dimensions should be checked before ordering?
Verify the corner radius (0.8 mm), insert thickness (3.97 mm), relief angle (11°) and ISO designation CPMT09T308 against the holder and application requirements to ensure correct fit and performance.
