CPMT 09T302 AH8015 rhombic indexable insert for turning — Tungaloy

CPMT 09T302 AH8015 is an ISO‑standard rhombic turning insert designed for external and internal turning of heat‑resistant alloys and similar demanding materials

• ISO rhombic insert, 80° cutting angle
• PVD‑coated carbide grade AH8015
• 0.2 mm corner radius for fine finishing
• Single‑sided chipbreaker with central hole

Consistent cutting performance where process reliability matters

The insert delivers a predictable cutting result thanks to its 80° geometry and PVD‑coated carbide construction. The 80° rhombic shape provides robust engagement and stability on external and internal turning operations, while the AH8015 grade balances wear resistance and edge stability for long tool life. These technical choices reduce the need for frequent insert changes and support steady cycle times, helping to maintain throughput in production environments.

Optimised edge form and surface quality for tighter tolerances

With a 0.2 mm corner radius and a single‑sided chipbreaker, the geometry is tailored for finishing and moderate roughing, producing consistent surface finishes with minimal vibration. The 11° relief angle and 3.97 mm plate thickness contribute to a secure seating in compatible holders, which in turn preserves dimensional accuracy. For components that demand repeatable surface integrity, the combination of small corner radius and PVD coating helps to safeguard the cutting edge against thermal softening and edge rounding.

Clear compatibility and secure clamping for straightforward integration

The insert follows ISO standards for form, relief angle, tolerance class, attachment and thickness, so compatibility with holders is determined by those parameters. The central cylindrical hole with a single‑side countersink (40°–60°) enables standard clamp or screw fixation in ISO‑compliant external holders or boring bars. Typical system assemblies include the insert, a matching external holder or boring bar, a shim or clamping set and replacement screws — this modular approach simplifies stock management and reduces setup times.

Practical benefits for workshop productivity and material versatility

This grade is specified as a first choice for machining heat‑resistant alloys, offering a pragmatic balance between edge stability and wear performance. The PVD coating enhances tool life under elevated temperatures, which is particularly valuable when machining alloys with lower thermal conductivity. Selecting the appropriate chipbreaker and matching the insert geometry to the machining stability and feed conditions yields measurable improvements in cycle consistency and component quality.

FAQ

What materials is this insert best suited for?
The CPMT 09T302 AH8015 insert is specified as a first choice for heat‑resistant alloys; the AH8015 grade and PVD coating provide a balance of wear resistance and edge stability for these materials.

How is the insert secured in the holder?
The insert uses a central cylindrical hole with a single‑side countersink (40°–60°) for clamp or screw mounting; compatibility requires matching form, relief angle, tolerance class, size and thickness with the chosen ISO‑compliant holder.

What surface finish can be expected with a 0.2 mm corner radius?
A 0.2 mm corner radius supports fine finishing and consistent surface quality when combined with an appropriate feed rate and the single‑sided chipbreaker, helping to reduce vibration and produce repeatable results.

Is this insert suitable for both external and internal turning?
Yes, the rhombic geometry and indexed design are suitable for both external and internal turning operations when the holder and process parameters are matched to the application.
