CNMG120416 AH6225 indexable turning insert for turning — Tungaloy

CNMG120416 AH6225 is a standard ISO indexable turning insert designed for external and internal turning applications where a balance of sharpness and cutting edge stability is required

• ISO rhombic 80° geometry
• PVD-coated cemented carbide AH6225
• 1.6 mm corner radius for robust edges
• Double-sided chipbreaker with cylindrical hole

Reliable performance for stainless steel machining

The CNMG120416 AH6225 insert combines a PVD-coated cemented carbide substrate with a universal grade developed specifically for stainless steels, delivering a sharp yet durable cutting edge during medium machining operations. This balance reduces the frequency of tool changes and supports steady cycle times in small- to medium-batch production. The 80° rhombic shape provides stable cutting forces and good accessibility for external and internal profiles, while the 1.6 mm corner radius helps maintain edge strength under interrupted cuts. Such design choices translate into predictable tool behaviour and improved process stability on conventional and CNC turning centres.

Improved chip control and edge life for consistent results

A double-sided chipbreaker matched to the universal AH6225 grade promotes effective chip formation across varying cutting conditions, which reduces the risk of built-up edge and improves surface finish. The PVD coating enhances wear resistance at the cutting edge and contributes to a longer effective tool life, especially when machining work‑hardening stainless alloys. Where thermal and mechanical conditions change during a shift, this insert maintains a reliable cutting geometry, lowering scrap rates and supporting repeatable part quality — a practical advantage for manufacturers aiming for consistent throughput.

System compatibility and straightforward handling

The insert conforms to ISO standards; compatibility with a holder depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness. The plate is double-sided and supplied with a cylindrical hole for secure clamping, enabling economical indexation and simple rotation for renewed cutting edges. Using standard ISO holders and the correct seat and clamp components ensures secure fixation and repeatable positioning. For workshops requiring quick tool changes, this indexable solution minimises downtime and simplifies inventory by using a universally recognisable insert shape and size.

FAQ

What materials is this insert intended for?
The CNMG120416 AH6225 insert is formulated as a universal grade for stainless steels, offering a good compromise between sharpness and edge stability for medium machining.

Can the insert be rotated or indexed to a second edge?
Yes, the plate is double-sided and designed for economical indexation to expose a fresh cutting edge, extending usable life per insert.

Which insert geometry does CNMG120416 use and why does it matter?
The insert features an 80° rhombic geometry, providing robust cutting force distribution and improved access for external and internal turning tasks.

How does the PVD coating benefit production?
The PVD coating increases wear resistance at the cutting edge, reducing flank wear and improving tool life under variable cutting conditions.

Is this insert compatible with standard ISO holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and thickness; matching the CNMG120416 dimensions to a corresponding ISO holder ensures correct fit and secure clamping.
