CPMT060204 AH6225 — Tungaloy ISO turning indexable insert for turning, PVD-coated carbide

A CPMT060204 AH6225 indexable insert designed for ISO-standard turning operations; optimised for stainless-steel applications with a sharp yet robust cutting edge and standard mounting features for secure clamping.

• PVD-coated carbide grade AH6225
• Universal for stainless steel turning
• Rhombic 80° geometry, 0.4 mm radius
• Cylindrical hole with single-side countersink

Predictable fit and simple ISO compatibility

The insert follows ISO norms, so compatibility with holders is governed by form, relief angle, tolerance class, fastening style, size and thickness rather than proprietary geometry. That standardisation simplifies tooling logistics and reduces the effort of selection: matching a standard CPMT insert to a compatible outer holder or boring bar, plus the correct shim and clamping set, avoids costly trial-and-error. The inclusion of a cylindrical hole with a single-side countersink (40°–60°) ensures secure fastening and repeatable seating, which translates into a steady production process and predictable downtimes.

Enhanced cutting performance for stainless steels

The AH6225 grade is a PVD-coated carbide designed as a universal solution for stainless steel machining. The combination of a comparatively sharp cutting edge and a stable substrate delivers a balance between reduced cutting forces and edge retention under medium machining conditions. The PVD coating improves resistance to built-up edge and thermal wear, leading to more consistent part surface quality and fewer unscheduled insert changes. In practice, this means longer uninterrupted runs and a better cost-in-use profile when processing reactive or work-hardening stainless alloys.

Practical geometry and application guidance

The 80° rhombic geometry with a 0.4 mm corner radius is suited to both external and internal turning where a compromise between finish and edge strength is required. The 2.38 mm plate thickness and 11° clearance angle support stable mounting and effective chip control when paired with the correct one-sided chipbreaker for the chosen operation. A 0.4 mm radius improves edge strength compared with very fine radii while still allowing acceptable surface finish on turned faces; select a smaller or larger radius only if the machining strategy or part specification explicitly demands it. For system set-up, ensure the holder profile, tolerances and screw type match the ISO designation to maintain clamping integrity and repeatable cutting geometry.

FAQ

Is this insert suitable for stainless-steel turning?
The AH6225 grade is formulated for stainless steel turning; the CPMT060204 insert offers a sharp yet stable cutting edge suited to medium operations on such alloys.

Which holder types are compatible with this ISO insert?
Compatibility is defined by the insert form, relief angle, tolerance class, fastening and thickness — the ISO designation CPMT060204 matches standard ISO external holders and boring bars when the holder specification references the same insert code.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm radius increases edge strength and tends to produce a robust finish; for finer surface requirements, a smaller radius or an alternate insert geometry should be selected.

Does the insert require a specific chipbreaker?
Chipbreaker choice should be matched to the workpiece material, machining type and machine stability; the supplied one-sided chipbreaker suits general turning but can be changed for heavy roughing or fine finishing.
