CCMT120404 AH8005 Tungaloy turning insert — PVD-coated carbide, 0.4 mm corner radius

A CCMT120404 AH8005 turning insert designed for external and internal turning of heat-resistant alloys and hard materials, offering a balance of wear resistance and process stability.

• PVD-coated carbide AH8005 for long tool life
• Rhombic ISO CCMT form, 80° cutting geometry
• 0.4 mm corner radius for fine finishing
• Central hole with cylindrical seat and countersink

Durable grade for heat-resistant and hard materials

The AH8005 grade is a PVD-coated carbide developed for wear resistance under elevated cutting temperatures. As a hard, coated grade, it reduces flank and crater wear compared with uncoated grades; this translates directly into longer tool life and fewer indexings. For workshops machining heat-resistant alloys or hardened components, the combination of a robust substrate and a thin, adherent coating provides thermal stability and consistent cutting-edge performance, enabling fewer tool changes and improved productivity.

Stable geometry that supports precise turning operations

Built to ISO CCMT120404 dimensions, the rhombic 80° form and the specified 7° relief angle create a geometry optimised for stable external and internal turning. The standardised shape ensures compatibility with common CCMT holders; the 80° included angle balances edge strength with accessibility in shoulder or profile turning. Because the insert is indexed rather than ground in situ, consistent tolerances help maintain process security across multiple indexings, contributing to reproducible surface finishes and dimensional control in serial production.

Controlled finishing and reliable chip control

With a 0.4 mm corner radius and a single-sided chipbreaker, the insert suits fine-finishing passes where surface quality is a priority. The modest corner radius helps limit cutting forces and vibration while still providing a durable cutting edge for light to moderate depths of cut. The chipbreaker geometry is matched to the AH8005 grade and the intended cutting parameters to promote predictable chip formation; controlled chips reduce risk of workpiece damage and improve machine uptime.

System-ready specification for straightforward integration

The insert is supplied in the ISO CCMT format with a central hole and a cylindrical seat plus a one-sided countersink (40°–60°), enabling secure clamping in standard holders. Plate thickness (4.76 mm) and size (12 mm) conform to common tooling systems, simplifying inventory and replacement logistics. Selecting the correct holder and tightening torque according to the holder manufacturer’s guidance preserves insert seat integrity and ensures repeatable seating; consultants can advise on the optimal holder and screw combination to match machining stability and the chosen grade.

For reliable machining of heat-resistant alloys and hard materials, order genuine Tungaloy CCMT120404 AH8005 turning inserts from Metav Werkzeuge or consult their specialists to ensure the correct holder and set-up for the application.

FAQ

What materials is this insert suited for?
The Tungaloy CCMT120404 AH8005 insert is formulated for heat-resistant alloys and hard materials; the AH8005 grade and PVD coating provide wear-resistant performance in demanding cuts.

Can the CCMT120404 AH8005 be used for both roughing and finishing?
Yes, the insert can be applied to finishing and light- to medium-duty turning; the 0.4 mm corner radius and single-sided chipbreaker favour fine finishing and controlled chip formation.

How is the insert mounted in a holder?
The CCMT120404 includes a central hole with a cylindrical seat and a one-sided countersink (40°–60°) for secure clamping in standard CCMT holders; correct holder selection and torque are essential for repeatable seating.

Does the AH8005 coating improve thermal stability?
The PVD-coated AH8005 grade enhances thermal resistance and reduces abrasive wear, which helps maintain cutting-edge integrity at higher cutting temperatures.

What identifiers should be quoted when ordering replacements?
Please reference the product designation CCMT120404 AH8005, the manufacturer article number 6749963 and the SKU 6749963-Tungaloy when placing orders.
