CNMG 120408 AH6235 ISO turning insert for turning — Tungaloy

A CNMG120408 AH6235 indexable insert designed for ISO-compliant external and internal turning, optimised for stainless-steel applications and interrupted cuts.

• PVD-coated carbide grade AH6235
• Designed for stainless steel and interrupted cuts
• Double-sided chipbreaker for improved control
• ISO rhombic CNMG 120408 profile, 0° clearance

Consistent cutting performance for stainless-steel turning

The PVD-coated carbide composition of this indexable insert provides a balance between toughness and wear resistance, making it suitable for stainless steel machining where built-up edge and notch wear are common. The AH6235 grade is formulated to resist chipping in interrupted cuts and areas with elevated breakout risk, reducing scrap and stabilising cycle times. Selecting a grade with enhanced fracture resistance directly lowers the frequency of tool changes and helps maintain consistent surface finish on prismatic and cylindrical components.

Improved chip control and process stability

Equipped with a double-sided chipbreaker, the insert controls chip formation across varying feed rates and depths of cut, which reduces rework and machine stoppages. The rhombic geometry and the implemented chipbreaker promote predictable chip flow during both light finishing passes and heavier turning operations, lowering the risk of entanglement and tool damage. As a result, process reliability increases, contributing to shorter set-up times and more efficient production runs for batch and single-part manufacture.

Clear compatibility and simple handling save set-up time

Configured to ISO dimensions, the rhombic CNMG profile with 0° clearance and a 0.8 mm radius ensures compatibility with a wide range of external holders and boring bars when matching form, relief angle and tolerance class. The insert thickness of 4.76 mm and the central cylindrical hole permit secure clamping and straightforward indexation, simplifying inventory management and tool change routines. Using an ISO-standard insert streamlines procurement and makes it easier to match the correct insert to existing toolholders.

Practical advantages and recommended applications

This indexable insert is particularly effective for operations that combine external turning, face turning and light internal turning where stainless-steel alloys and interrupted cuts occur. The grade’s toughness supports applications with variable engagement and the PVD-coated surface enhances resistance to thermal softening, which can extend cutting life under typical shop-floor conditions. For jobs requiring consistent edge integrity, this option reduces unplanned downtime and supports higher first-pass yields.

FAQ

What materials is this insert best suited for?
The CNMG120408 AH6235 insert is formulated for stainless steel and performs well in interrupted cutting conditions where toughness is required.

How does the chipbreaker affect machining?
The double-sided chipbreaker on this insert improves chip formation and evacuation, enhancing process stability and reducing the likelihood of chip-related interruptions.

Is this insert compatible with standard CNMG toolholders?
Yes, the insert follows ISO CNMG dimensions and will fit holders designed for the 120408 profile when form, clearance and tolerance class are matched.

What is the corner radius and how does it influence finish?
The insert has a 0.8 mm corner radius, which helps achieve a balance between edge strength and surface finish, suitable for medium- to fine-turning operations.

Can the AH6235 grade handle intermittent cuts?
The AH6235 grade is specifically selected for increased fracture resistance, making it suitable for interrupted cuts and applications with elevated breakout risk.
