CCMT 120408 AH6225 indexable turning insert by Tungaloy — PVD-coated carbide, 7° relief

CCMT 120408 AH6225 Tungaloy indexable turning insert for external and internal turning applications, offering a sharp yet stable cutting edge for medium machining and variable conditions

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• ISO CCMT 120408 form, 80° included angle
• 0.8 mm corner radius, single-side chipbreaker

Consistent cutting performance with PVD-coated carbide

The PVD-coated carbide composition of this insert provides a reliable balance between edge sharpness and wear resistance. The AH6225 grade is formulated as a universal option for machining stainless steel, delivering consistent tool life under fluctuating conditions. The PVD layer reduces adhesion and improves heat resistance, which helps maintain the cutting edge during medium-duty operations. This results in predictable cycle times and fewer indexings, supporting a smoother production flow and reduced machine downtime.

Easy integration into ISO tooling systems for predictable setup

Compatibility with tool holders is governed by form, relief angle, tolerance class, fastening, size and thickness; the ISO CCMT 120408 geometry ensures straightforward replacement and predictable clamping in standard external holders or boring bars. The insert’s 7° relief and 80° included angle contribute to positive cutting forces and good seat stability. The system concept comprises the indexable insert, matching external holder or boring bar, a shim or clamp set and spare screws, enabling quick assembly and reproducible clamping repeatability for serial operations.

Process reliability, surface quality and material coverage

A 0.8 mm corner radius improves resistance to edge chipping while supporting an acceptable surface finish on finished components. The single-side chipbreaker is tuned for dependable chip control in turning operations, reducing the risk of chip entanglement and improving operator safety. As a medium-range grade, the insert helps manage production costs by offering a favourable wear‑life profile and wide material coverage, making it a practical choice for mixed batches and workshops that require versatility without sacrificing stability.
