CPMT 080204 AH6235 ISO turning insert for external and internal turning — Tungaloy

CPMT080204 AH6235 is an ISO-format rhombic insert designed for robust turning operations, optimised for stainless-steel workpieces and interrupted cuts

• PVD-coated AH6235 for stainless steel
• Rhombic CPMT form, 80° included angle
• 0.4 mm corner radius for fine finishing
• With hole and single-side countersink 40°–60°

Optimised grade for demanding stainless-steel turning

The AH6235 grade is a PVD-coated carbide specifically developed for tougher machining conditions, such as stainless steel and interrupted cuts. The coating reduces built-up edge and improves heat resistance, which translates into longer tool life and fewer unplanned tool changes. In practice, this means a more consistent cutting action and reduced part-to-part variation when machining corrosive or work-hardening alloys. The tougher substrate paired with the surface treatment helps prevent edge breakouts in unstable conditions, offering a measurable gain in process reliability.

Stable cutting geometry for precision and repeatability

The rhombic CPMT geometry with an 80° included angle and 0.4 mm corner radius delivers a balanced mix of strength and surface finish. The 11° relief angle and 2.38 mm plate thickness provide sufficient support under load, while the central hole with cylindrical bore and one-sided countersink (40°–60°) ensures secure clamping in ISO-compliant holders. Together these features reduce vibration and promote a consistent chip formation, resulting in improved dimensional accuracy and extended insert life. The clear geometry also simplifies set-up checks and repeatable index changes during production.

System-level compatibility and practical selection advice

As an ISO turning insert, this component is intended to be used with a matching external holder or boring bar, plus the corresponding shim/clamp and fastening screws. Compatibility is governed by insert form, relief angle, tolerance class, fixation style, size and thickness, so selection should match the holder specification. Choose the one-sided chipbreaker style and the AH6235 grade when machining stainless steel or when facing a high risk of edge breakout; for other materials, select an alternative chipformer and grade optimised for the substrate. This approach minimises downtime and supports a productive machining workflow with consistent surface quality.

FAQ

What materials is this insert best suited for? The AH6235 grade is formulated for stainless steel and applications with interrupted cuts, so the CPMT080204 insert performs well where toughness and chipping resistance are required.

Which holder features are required for secure clamping? Secure clamping requires a holder compatible with the CPMT form, matching relief angle, correct tolerance class, appropriate fixation method and support for a 2.38 mm thick insert with the central hole and countersink.

Can the insert be used for finishing operations? Yes; with a 0.4 mm corner radius the insert can achieve good surface finishes, provided cutting parameters and holder rigidity are adapted for finishing passes.

How does the PVD coating benefit production? The PVD coating on the AH6235 grade improves heat resistance and reduces built-up edge, resulting in longer insert life and more consistent machining performance under demanding conditions.

Is this an ISO-standard insert and how does that help? Yes, the CPMT080204 is ISO-compliant; this ensures interchangeability with standard holders and simplifies tool management across machines.
