CCMT 120408 AH6235 indexable turning insert for turning — Tungaloy

The CCMT120408 AH6235 is an ISO-standard indexable turning insert engineered for external and internal turning, optimised for rostfreie Stähle and interrupted cuts where edge strength and reliable chip control are required.

• PVD-coated carbide grade AH6235 for rostfreie Stähle
• 0.8 mm nose radius for fine surface finish
• 7° clearance angle to reduce rubbing
• ISO CCMT120408 rhombic insert with central hole

Stable cutting performance for demanding stainless-steel turning

The PVD-coated AH6235 carbide delivers a balance of toughness and wear resistance that suits operations with increased risk of chipping and interrupted cuts. As an indexable turning insert, the grade is formulated to maintain edge integrity under variable cutting conditions, which reduces unplanned tool changes and supports steady cycle times. The PVD layer improves resistance to built-up edge and flank wear, while the substrate hardness preserves cutting edge stability; together these characteristics translate into more predictable tool life and consistent component quality.

Designed for safe system integration and correct seating

Compliance with the ISO designation CCMT120408 ensures straightforward selection of matching holders and tooling systems. Compatibility is determined by insert shape, relief (here 7° clearance), tolerance class, clamping method, size and thickness; matching the insert to a suitable CCMT holder and the required shim/clamp set secures repeatable seating and stable cutting conditions. The rhombic form with an 80° included angle provides versatility for general turning tasks, while the central hole with a cylindrical countersink (40°–60°) supports positive and secure fastening.

Efficiency gains through geometry and chip control

The one-sided chipbreaker and the 0.8 mm nose radius combine to deliver improved surface finish and controlled chip formation in many turning scenarios. For series production or mixed-batch work involving rostfreie Stähle and interrupted sections, this insert reduces cycle variability and supports higher process reliability. Choosing the correct chipbreaker and the AH6235 sort optimises swarf behaviour and minimises secondary operations, so machining becomes more economical and less prone to scrap — a concrete gain for production planning and shopfloor predictability.

FAQ

What is the primary application of this insert?
The CCMT120408 AH6235 indexable turning insert is intended for external and internal turning operations, especially where interrupted cuts or rostfreie Stähle are involved.

Which materials can this grade handle?
The AH6235 PVD-coated carbide is formulated for rostfreie Stähle and similar alloys where edge toughness and resistance to chipping are priorities.

How does one ensure the insert fits the holder correctly?
Compatibility depends on insert form, clearance angle, tolerance class, clamping style, size and thickness; matching these parameters with the selected CCMT holder ensures correct seating and stable machining.

Is this insert suitable for interrupted cuts?
Yes, the AH6235 grade was developed to withstand interrupted cuts and applications with elevated breakout risk, offering improved edge strength compared with standard grades.

What surface finish can be expected from the 0.8 mm nose radius?
A 0.8 mm nose radius offers a good compromise between edge strength and surface finish, enabling fine finishes on turned components while maintaining sufficient robustness.
