CNMG 160612 AH6225 CNMG160612 indexable insert – PVD-coated carbide for turning (80° rhombic, 1.2 mm radius) by Tungaloy

CNMG160612 AH6225 is an ISO-format indexable insert for general turning, designed for medium machining of rostfreien Stahl and variable production conditions

• PVD-coated carbide grade AH6225
• Optimised for rostfreien Stahl turning
• 80° rhombic form with cylindrical hole
• Double-sided insert, 1.2 mm corner radius

Consistent cutting performance under mixed conditions

The PVD-coated carbide grade AH6225 delivers a balance between a sharp and stable cutting edge, specifically optimised for machining rostfreien Stahl in medium-duty operations. The combination of the coating and the substrate increases resistance to built-up edge and abrasive wear, which translates into longer effective cutting life and fewer tool changes. The 1.2 mm corner radius stabilises the edge for reliable chip formation while the rhombic 80° geometry provides a compromise between strength and access—benefits that improve cycle-time predictability and part finish without sacrificing economy.

Quick integration into ISO tooling systems and secure clamping

This ISO-format insert conforms to established holder interfaces; compatibility depends on form, clearance angle, tolerance class, attachment, size and thickness, so the correct match with a suitable external holder or boring bar is essential. The insert measures with a nominal size of 16 and a plate thickness of 6.35 mm, presented double-sided with a cylindrical hole, enabling reversal to extend service life. The standardised design simplifies stocking: a single SKU covers two usable edges per side, supported by common shims, clamping kits and replacement screws for straightforward assembly in most ISO-compatible turning systems.

Productivity advantages and application guidance

The CNMG160612 AH6225 insert is intended for external and internal turning where moderate material removal and changing workpiece conditions occur. The double-sided chipbreaker design assists in controlled chip segmentation across varying feed rates, reducing interruptions and protecting the workpiece surface. Selecting the appropriate chipbreaker and grade according to component rigidity and cutting parameters optimises results; in less stable set-ups a smaller depth of cut or reduced feed helps maintain edge life. The combination of these design choices supports higher process reliability and efficient part output with predictable tool-change intervals.

FAQ

What materials is this insert suitable for?
This CNMG160612 AH6225 insert is formulated for rostfreien Stahl and general turning tasks where a durable, sharp cutting edge is required.

Can the insert be flipped or reversed?
Yes, the insert is double-sided; both sides can be used to extend service life, subject to correct orientation in the clamping system.

Which holder characteristics must be checked for compatibility?
Compatibility is determined by the insert form, clearance angle (0° free angle), tolerance class, attachment method, size and thickness; ensure the holder supports a CNMG 80° rhombic insert with a cylindrical hole.

How does the PVD coating affect cutting performance?
The PVD-coated carbide grade improves wear resistance and helps maintain a sharp edge under changing conditions, enhancing tool life and surface quality on rostfreien Stahl.

Is this insert suitable for finishing and semi-finishing?
The geometry and 1.2 mm corner radius make it suitable for medium machining and semi-finishing; for delicate finishing pass parameters should be adjusted to reduce edge load.
