CCMT120408 AH6235 Tungaloy indexable turning insert — PVD-coated carbide for turning

A CCMT120408 AH6235 indexable turning insert designed for general and interrupted turning of stainless steels, offering a robust geometry and ISO compatibility for reliable workshop performance.

• PVD-coated carbide for stainless steels
• Rhombic CCMT shape with 7° clearance
• 0.8 mm corner radius for robust cutting edge
• Cylindrical hole with 40°–60° countersink

Increased productivity for stainless-steel turning

The PVD-coated carbide grade AH6235 delivers higher resistance to edge chipping in demanding environments, making it particularly effective for rostfreie Stähle and interrupted operations. The coating improves wear behaviour at elevated interface temperatures while the substrate provides toughness for unstable cutting conditions. As a result, machining cycles benefit from fewer insert changes, more consistent surface finishes and predictable tool life, which contributes directly to process efficiency and reduced operating cost.

Secure fit and straightforward holder compatibility

Belonging to the ISO series of indexable turning plates, compatibility is determined by shape, clearance angle, tolerance class, fastening style, size and thickness. The rhombic CCMT outline and its 7° clearance angle ensure correct seating in standard CCMT holders, while the presence of a cylindrical hole with single-sided countersink (40°–60°) facilitates accurate centring and reliable clamping. This structured system design enables reproducible set-ups and minimises the time needed for insert replacement.

Robust geometry to reduce interruptions and scrap

A corner radius of 0.8 mm combined with a plate thickness of 4.76 mm provides a balance between edge strength and cutting versatility. The one-sided chipbreaker supports controlled chip formation in many stainless-steel cutting regimes, reducing the risk of edge breakout during variations in feed or interrupted cuts. Better chip control and a stable cutting edge translate into fewer rejects and a steadier surface quality, especially when machining parts with frequent interruptions or variable material consistency.

Practical selection and machining recommendations

Select a matching chipbreaker and the AH6235 grade when priority is resistance to chipping and consistent performance on tougher-to-machine alloys. Optimise cutting parameters for reduced heat build-up: moderate cutting speeds and steady feed rates are typically advantageous for rostfreie Stähle; coolant strategy should favour effective heat extraction. Metav Werkzeuge’s technical advisors can assist with holder selection and process parameters to align the insert’s strengths with specific production goals, ensuring the right combination of grade, geometry and clamping for each application.

FAQ

What materials is this insert suitable for? The CCMT120408 AH6235 insert is intended primarily for rostfreie Stähle and other demanding alloys where resistance to chipping is required.

How does the AH6235 grade differ from general-purpose grades? AH6235 is a tougher, PVD-coated carbide grade that favours interrupted cutting and applications with increased breakout risk, offering longer edge life compared with standard grades.

How is compatibility with a holder determined? Compatibility depends on the insert’s shape, clearance angle, tolerance class, fastening style, size and thickness; the CCMT form and 7° clearance ensure fit with standard CCMT holders.

Does this insert have a locating hole and countersink? Yes — the insert includes a cylindrical locating hole with a single-sided countersink specified at approximately 40°–60° to aid accurate seating and clamping.

What is the corner radius and why does it matter? The corner radius is 0.8 mm; this radius increases edge strength and helps to reduce chipping during interrupted cuts while influencing surface finish and allowable feed rates.
