CNMG090408 AH6225 Tungaloy turning insert — ISO turning insert, 0° clearance, 0.8 mm radius

A CNMG090408 AH6225 indexable turning insert designed for external and internal turning in variable conditions, optimised for rostfreier Stahl applications and medium cutting depths.

• CNMG geometry for versatile turning
• PVD-coated AH6225 grade for rostfreier Stahl
• 0.8 mm corner radius for controlled cutting
• Cylindrical hole with 0° clearance for secure clamping

Consistent edge life for productive turning operations

The insert is manufactured from carbide and finished with the PVD-coated AH6225 grade to deliver a combination of sharpness and edge stability. This composition reduces flank wear under fluctuating cutting conditions, which leads to fewer interruptions for index changes and lower overall tool consumption. The result is improved machine uptime and more predictable cycle times during series production and jobbing alike. The geometry and coating choice are geared towards efficiency in medium-duty turning rather than extreme high-speed or heavy interrupted cuts.

Precision geometry and clamping ensure process security

The rhombic CNMG form with an 0.8 mm corner radius and an 80° wedge angle provides a well-balanced contact area that supports dimensional accuracy and surface finish. A 0° clearance combined with a cylindrical hole and standard ISO fixing positions enables straightforward seating in compatible external holders or boring bars; compatibility is governed by form, clearance angle, tolerance class, fastening type, size and thickness. The double-sided chipbreaker offers repeatable chip control for turning processes, reducing the risk of chip entanglement and improving surface integrity on workpieces in rostfreier Stahl.

System approach for safe integration and predictable results

Integration into a turning system requires the matched holder, clamping set and replacement screws to maintain the expected tolerance chain. The insert thickness of 4.76 mm and the ISO size 09 are typical for many standard holders, while the double-sided design permits cost-efficient indexing and continuous use before disposal. Traceable identifiers (manufacturer SKU and article number) support process documentation and reordering. Specification-driven selection of chipbreaker and grade ensures the cutting edge remains productive across varying feeds and depths, delivering repeatable component quality and reduced rework rates.

FAQ

What materials is this insert best suited for?
The CNMG090408 AH6225 insert is optimised for rostfreier Stahl; the AH6225 PVD-coated grade balances sharpness and edge stability for medium-duty turning of stainless steels.

How does the 0° clearance affect holder selection?
A 0° clearance requires holders designed to accept neutral-clearance inserts; compatibility is determined by form, tolerance class and fastening, so the correct holder geometry must be selected for secure seating of the CNMG090408 AH6225 insert.

Is the insert indexable on both sides?
Yes, the insert is double-sided with a chipbreaker on each cutting edge, allowing economical indexing and extended tool utilisation before replacement.

Which dimensions are critical when matching a holder?
Critical dimensions include the plate thickness (4.76 mm), plate size (09), corner radius (0.8 mm) and the ISO-defined form; these determine correct engagement and clamping in the holder.

Can this insert be used for internal turning?
The geometry and chip control of this indexable insert permit use in both external and internal turning operations, provided an appropriate boring bar or internal holder is used.
