CCMT120404 AH6225 Tungaloy ISO turning insert — PVD-coated carbide, 80° rhombic

CCMT120404 AH6225 Tungaloy is an ISO-standard indexable insert for general turning applications, designed for reliable performance on rostfreier Stahl and similar materials.

• PVD-coated carbide for improved wear resistance
• Optimised for rostfreier Stahl machining
• Rhombic 80° geometry with 0.4 mm radius
• Central bore with cylindrical hole and 40°–60° countersink

Reliable cutting-edge performance for medium turning

The PVD-coated carbide grade AH6225 delivers a sharp but stable cutting edge, specifically formulated for medium machining and changing conditions. This indexable insert provides consistent cutting behaviour through a balance of toughness and wear resistance, reducing the need for frequent tool changes. Compatibility is governed by insert form, clearance angle, tolerance class, clamping and thickness; the ISO standard geometry allows straightforward selection of matching holders and adapting existing tool systems.

Geometry that balances strength and accessibility

The 80° rhombic geometry with a 0.4 mm radius offers a practical compromise between corner strength and accessibility for finish and semi-finish turns. The 80° angle increases rigidity for heavier cuts, while the modest corner radius helps maintain surface quality. The insert features a 7° relief angle and a 4.76 mm thickness, ensuring secure clamping and repeatable positioning in appropriately rated toolholders, which in turn supports stable machining and predictable tool life.

Built-in chip control and secure fixing for process stability

A one-sided chipbreaker adapts chip formation to general turning tasks, promoting controlled evacuation and reducing the risk of built-up edge when machining challenging stainless alloys. The insert is supplied with a central hole and a cylindrical bore plus a single-sided countersink (40°–60°) for secure fixing and precise seating; this reduces vibration and contributes to consistent surface finishes during production runs.

Practical selection advice and system considerations

As an ISO-series insert, CCMT120404 AH6225 should be chosen together with a compatible external holder or boring bar plus the correct shim/clamp set and replacement screws for a complete system. When processing rostfreier Stahl, select the chipbreaker and grade combination that matches feed, depth of cut and machine rigidity to benefit from the AH6225 blend of edge sharpness and wear resistance. The result is improved cycle-time reliability and lowered scrap rates through consistent chip control.

FAQ

What materials is this insert suitable for?
The CCMT120404 AH6225 Tungaloy insert is designed primarily for rostfreier Stahl and similar stainless alloys; the AH6225 grade balances edge sharpness and toughness for medium turning.

How does the PVD coating benefit production?
The PVD-coated carbide finish on the CCMT120404 AH6225 improves wear resistance and temperature tolerance, extending tool life and maintaining a stable cutting edge under varying conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, clamping style, insert size and thickness; select an 80° rhombic external holder or boring bar specified for ISO CCMT inserts and confirm clamping hardware fits the central bore and countersink.

What cutting tasks suit the 0.4 mm radius?
A 0.4 mm radius is suitable for semi-finish and light roughing where a balance of surface quality and edge strength is required; it provides improved accessibility over larger radii while retaining sufficient corner durability.

Does the insert require special mounting hardware?
The insert uses a central bore with a cylindrical hole and a countersink (40°–60°); use the matching shim/clamp set and replacement screws designed for ISO CCMT inserts to ensure secure, repeatable mounting.
