CCMT 060204 AH120 – Indexable turning insert for Turning by Tungaloy, PVD‑coated carbide, 0.4 mm radius

The CCMT060204 AH120 is an ISO‑standard indexable turning insert designed for external and internal turning, offering a wear‑ and chipping‑resistant PVD‑coated carbide grade for demanding production environments.

• PVD-coated carbide for high wear resistance
• 0.4 mm corner radius for precise profiling
• 7° clearance angle for stable cutting
• ISO CCMT form with wide holder compatibility

Reliable cutting performance for production turning

The insert is engineered to deliver process reliability in series production by combining a wear‑resistant grade with a robust geometry. The PVD‑coated surface reduces flank wear and helps maintain a sharp edge for longer intervals, which translates into fewer tool changes and more consistent part quality. The design supports both roughing and finishing when the correct chipbreaker and cutting parameters are chosen, so productivity increases without compromising surface integrity.

Grade AH120 and coating advantages explained

The AH120 grade is a PVD‑coated carbide formulation optimised for resistance to wear and micro‑chipping under intermittent and continuous cuts. In practice, this means improved edge stability when a crisp cutting edge is required together with predictable tool life. For customers unfamiliar with coating technology: PVD coating applies a thin, hard layer that improves resistance to abrasion and heat, while the substrate carbide provides toughness—this combination helps balance durability with sharpness for stable machining.

Geometry and compatibility that simplify setup

The rhombic CCMT geometry with an 80° included angle and 0.4 mm corner radius produces controlled chip formation and accurate profile reproduction. The 7° relief angle reduces friction behind the cutting edge, supporting steady cutting forces and lower tool deflection in many turning set‑ups. The insert is supplied with a hole and a cylindrical hole plus one‑sided countersink (40°–60°), ensuring secure clamping in compatible holders; compatibility is determined by form, relief angle, tolerance class, attachment, size and thickness.

Practical selection and process recommendations

Select the one‑sided chipbreaker variant and the AH120 grade when a balance of sharp edge and chipping resistance is required; choose the appropriate chipbreaker and cutting data according to material and stability of the set‑up. For unstable set‑ups favour a smaller depth of cut and conservative speeds; for rigid, well‑supported components, increased feed and speed will raise productivity. The insert’s ISO CCMT designation ensures it fits standard external or boring holders designed for CCMT inserts, provided the holder matches the insert form, thickness and clamping style.

FAQ

What turning tasks is this insert intended for?
The CCMT060204 AH120 insert by Tungaloy is intended for external and internal turning operations; choose the appropriate chipbreaker and cutting data for the specific material and stability of the set‑up.

How does the AH120 grade affect tool life and edge stability?
The AH120 PVD‑coated carbide grade is formulated to resist wear and micro‑chipping, offering stable cutting edges and extended tool life under many turning conditions.

Which holder features are required for correct compatibility?
Compatibility depends on the holder matching the insert form, relief angle, tolerance class, attachment method, size (06) and thickness (2.38 mm); the CCMT form is ISO‑standard and fits holders designed for CCMT inserts.

What is the benefit of the 0.4 mm corner radius?
A 0.4 mm corner radius provides finer profile control and improved surface finish compared with larger radii, while still offering edge strength for many finishing and light‑roughing cuts.

What does the hole and countersink specification mean for clamping?
The insert is supplied with a hole and a cylindrical hole plus one‑sided countersink (40°–60°), which enables secure clamping and correct seating in compatible indexable holders.
