CCMT120412 AH6235 — CCMT indexable insert for turning, Tungaloy

The CCMT120412 AH6235 is an ISO‑standard indexable turning insert optimised for external and internal turning, particularly suited to stainless steels and interrupted cuts.

• PVD-coated carbide AH6235 grade
• 1.2 mm nose radius
• With cylindrical hole and countersink
• Optimised for interrupted cuts and stainless steels

Increased productivity with a tougher grade

The combination of a PVD‑coated carbide substrate and the AH6235 grade produces a tougher insert that is designed to resist chipping during intermittent cuts. This composition reduces unplanned tool changes and leads to a more predictable tool life; the PVD coating improves surface hardness and reduces adhesive wear while maintaining toughness. For applications involving stainless steels or other work‑hardening materials, this balance results in improved cycle times and fewer rejects, translating directly into cost efficiency on the shop floor.

Easy integration into ISO turning systems

The rhombic CCMT shape with an 80° included angle and ISO designation guarantees compatibility with standard CCMT holders when form, clearance angle, tolerance class, fastening method, size and thickness match. The insert’s dimensions — 12 mm across and 4.76 mm thickness — combined with the cylindrical hole and single‑side countersink (40°–60°) allow secure clamping and simple positioning. This compatibility reduces setup time and allows predictable clamping forces, which in turn stabilise cutting conditions and improve repeatability across batches.

Controlled profile and chip management for consistent finishes

A 1.2 mm nose radius offers a good compromise between edge strength and contour fidelity, enabling stable feeds while helping to maintain surface quality on the workpiece. The 7° clearance angle and the single‑side chipbreaker geometry promote reliable chip formation and evacuation; this is especially important when machining interrupted surfaces or tougher alloys. The resulting machining behaviour supports consistent surface finish and dimensional accuracy, lowering the time needed for subsequent finishing operations.

FAQ

What materials is this insert best suited for?
The CCMT120412 AH6235 is formulated for tough applications and is especially effective on stainless steels and other materials prone to work hardening; the AH6235 grade provides improved resistance to chipping.

How is the insert secured in the toolholder?
The insert features a cylindrical hole with a single‑side countersink (40°–60°) and is clamped in standard CCMT holders that match the ISO form, clearance angle and thickness.

What advantage does the PVD coating provide?
The PVD coating on the carbide substrate enhances surface hardness and reduces adhesive wear while preserving toughness, which helps maintain edge life and consistent cutting behaviour under interrupted conditions.

Can this insert be used for both internal and external turning?
Yes, the geometry and CCMT form make the insert suitable for both external and internal turning operations when paired with the appropriate holder and setup.

Which product code should be ordered for this insert?
Order reference details include article number 6903453 and manufacturer SKU TUN6903453 for the CCMT120412 AH6235 Tungaloy indexable insert.
