CPMT 09T308 AH8005 Wendeplatten - Tungaloy

Reliable machining of heat‑resistant alloys and hard materials is achieved by combining the PVD‑coated carbide AH8005 grade with the 80° rhomboid geometry and a 0.8 mm corner radius for consistent surface finish and extended tool life. The ISO CPMT09T308 form ensures precise seating in standard holders. Order the insert directly via Metav Werkzeuge or consult the specialists for application‑specific recommendations.

CPMT 09T308 AH8005 turning insert — Tungaloy

A CPMT09T308 AH8005 ISO rhombic turning insert engineered for stable external and internal turning of heat‑resistant alloys and hard materials.

• ISO rhombic insert CPMT 09T308
• PVD-coated carbide grade AH8005
• 80° cutting angle, 11° clearance
• Single-sided chipbreaker, corner radius 0.8

Increased productivity through robust grade and geometry

The combination of a PVD coating with a wear‑resistant carbide substrate in grade AH8005 delivers improved edge stability during sustained cuts. This construction reduces flank wear and extends effective tool life, which leads to fewer indexings and less downtime. The 80° cutting angle gives a strong cutting edge suited to interrupted cuts and heavy feeds, while the 0.8 mm corner radius contributes to a predictable surface finish. For production environments seeking higher throughput, this geometry and grade help maintain consistent cycle times and reduce tooling costs per component.

Interchangeability and reliable clamping for easy integration

Compliance with ISO form CPMT09T308 ensures that the insert fits a wide range of standard external holders and boring bars when form, relief angle, tolerance class, fastening type, size and thickness match. The CPMT shape and the specified 11° clearance help avoid unwanted rubbing and ensure stable contact in the seat. The rhomboid design offers flexibility for both external and internal turning operations and simplifies inventory management, since compatible insert families and holder systems can be used across multiple machining tasks.

Application guidance and material suitability explained

The cutting material is optimised for machining heat‑resistant alloys and hard materials under stable machining conditions. The PVD coating provides a thin, hard layer that improves wear resistance and thermal stability; this is particularly beneficial when working with tough superalloys or hardened workpieces. For customers unfamiliar with the terminology: PVD (physical vapor deposition) forms a protective film on the carbide substrate to reduce adhesion and crater wear, while the carbide core maintains edge strength. Selecting the correct chipbreaker and cutting parameters is essential to exploit these benefits and achieve the desired surface integrity.

Practical handling, mounting and system considerations

The insert is supplied in the ISO CPMT09T308 form with a cylindrical hole and single‑sided countersink (40°–60°), compatible with common clamping screws and seat designs. The plate thickness of 3.97 mm and the single‑sided chipbreaker are tailored for stable turning; the chipbreaker helps control swarf in continuous cuts and supports predictable chip formation. Where system assembly is required, use the appropriate external holder or boring bar together with the correct shim/clamp set and replacement screws to secure repeatable clamping. For demanding or variable conditions, match the chipbreaker and grade to the workpiece material and rigidity of the setup to maintain process reliability.

FAQ

What materials is this insert best suited for? The CPMT09T308 AH8005 insert is optimised for heat‑resistant alloys and hard materials; the PVD‑coated carbide grade AH8005 improves wear resistance in these applications.

How does the ISO designation affect holder compatibility? ISO form CPMT09T308 indicates the rhombic shape and standard dimensions, which facilitates compatibility with holders and boring bars designed for CPMT inserts when form, thickness and fastening match.

Which chipbreaker is fitted and what is its effect? This insert features a single‑sided chipbreaker, designed to promote predictable chip formation during stable turning operations and to aid evacuation in continuous cuts.

What mounting features must be observed during assembly? The plate has a cylindrical hole with a single‑sided countersink (40°–60°); use the correct clamp/shim and screw torque for repeatable clamping and to avoid seating errors.

Can the insert be used for interrupted cuts? Yes — the 80° cutting angle provides a robust cutting edge suitable for interrupted cuts and applications requiring higher edge strength.
