CPMT 080208 AH6235 — ISO turning insert, PVD-coated carbide · Tungaloy

The CPMT080208 AH6235 is an ISO rhombic turning insert engineered for external and internal turning, offering a single-sided chipbreaker and a cylindrical hole with one-sided countersink for secure fastening.

• ISO rhombic geometry for standard holders
• PVD-coated carbide grade AH6235 for stainless steels
• Single-sided chipbreaker for interrupted cuts
• Cylindrical hole with 40°–60° countersink

Proven cutting performance for stainless steels and critical edges

The combination of a PVD-coated surface and a carbide substrate provides improved edge stability and resistance to notch wear, which is particularly valuable when machining stainless steels or materials prone to built-up edge. The chosen grade delivers a balance between toughness and wear resistance, reducing the risk of premature fracturing during interrupted cuts. This results in longer indexable life and fewer insert changes, supporting continuous production and predictable tool costs.

Geometry that secures repeatable clamping and consistent finishes

Designed to the ISO series, the rhombic shape and precise geometry ensure compatibility with standard indexable holders; clamping fit depends on form, clearance, tolerance class, fastening method, size and thickness. The insert offers an 11° clearance and an 80° included angle, combined with a 2.38 mm thickness, to provide a stable cutting edge and reduce vibration transmission. These geometric details make it easier to achieve consistent surface quality and repeatable results across batches.

Application advantages for turning and interrupted operations

The insert is tailored for both external and internal turning, where interrupted or unstable cuts are common; the single-sided chipbreaker supports chip control and mitigates the risk of edge chipping in those conditions. A 0.8 mm radius helps to spread cutting forces over a larger edge area, improving strength at the cutting corner and enabling slightly more aggressive feeds without compromising edge life. This makes the insert suitable for operations where robustness and predictable tool behaviour are priorities.

System compatibility and logistic benefits for production environments

As part of a conventional ISO insert system, the item integrates with a matching outer holder or boring bar, backing plate/clamping set and replacement screws, simplifying inventory and reordering. Identifiers such as the manufacturer SKU support traceability in procurement and tool management. The combination of a standardised geometry and a robust PVD-coated grade reduces the need for special clamping solutions and helps to maintain steady machining throughput with fewer interruptions.

FAQ

Is this insert suitable for stainless steels?

Yes. The CPMT080208 AH6235 is a PVD-coated carbide insert formulated for machining stainless steels and for applications with higher break-out risk.

Which turning operations are recommended for this type of insert?

Suitable operations include external and internal turning, especially where interrupted cuts occur; the single-sided chipbreaker supports chip control in such tasks.

How is holder compatibility determined for this insert?

Compatibility is governed by the insert form, free (clearance) angle, tolerance class, fastening method, size and thickness; matching these parameters with the chosen ISO holder ensures secure clamping.

What is the corner radius and how does it affect machining?

The corner radius is 0.8 mm, which increases edge strength and allows more stable cutting under variable engagement, helping to reduce chipping in interrupted or unstable cuts.

What fastening style does the insert use?

The insert features a cylindrical hole with a one-sided countersink (40°–60°), designed for screw fastening in standard clamping arrangements.

Are additional system parts required to use the insert?

Yes. A matching external holder or boring bar, a backing plate or clamping set and suitable replacement screws complete the system for safe and repeatable use.
