CNMG 190616 AH6225 Tungaloy Turning Insert — PVD-coated carbide, 80° rhombic

The CNMG190616 AH6225 is an ISO rhombic turning insert designed for external and internal turning, optimised for stainless steel and for applications requiring a stable cutting edge in mixed production conditions.

• ISO rhombic insert CNMG190616, 80° geometry
• PVD-coated carbide AH6225 for stainless steel
• 1.6 mm corner radius for stable cutting
• Double-sided chipbreaker with cylindrical hole

Consistent edge stability for medium turning

The AH6225 grade, presented as a PVD-coated carbide, combines a sharp but robust cutting edge that is aimed at medium machining and fluctuating operational conditions. This composition delivers a stable cutting edge under varying feeds and depths, which means fewer unexpected interruptions and a more consistent surface finish. For shops processing stainless steel, the grade balances wear resistance and edge toughness: the coating helps reduce built-up edge while the substrate maintains integrity under intermittent loads. Translating material performance into production terms, the result is predictable tool life and reduced rework, supporting higher first-pass yield.

Designed for straightforward toolholder compatibility

The insert follows the ISO CNMG specification and the 80° rhombic geometry, which supports wide holder availability and simple indexability. The plate’s 6.35 mm thickness and the cylindrical hole ensure secure clamping in compatible holders; compatibility is determined by form, clearance angle, tolerance class, fastening type, size and thickness. The corner radius 1.6 mm offers a balance between edge strength and dimensional control: it dampens vibration better than a fine radius while still permitting decent profile definition. For workshops standardising on ISO tooling systems, this configuration reduces inventory complexity and shortens setup times.

Operational benefits: productivity and process security

Built as a double-sided insert with a doppelseitig chipbreaker design, the plate provides two indexed edges per side where applicable, helping to extend the usable life before disposal or regrinding. The chipbreaker geometry assists in controlled chip formation when machining stainless steel, lowering the risk of long, stringy chips and improving evacuation. Together, productive machining and maintained edge stability translate into lower downtime and a more consistent component quality. For manufacturing environments where repeatability and process security are priorities, this insert supports steady cycle times and reliable finishing, making it a pragmatic choice for mixed-batch turning operations.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The AH6225 grade and PVD-coated carbide construction are specified for universal use on stainless steel, offering a balanced edge that copes with the material's demands.

Can the CNMG190616 be used for internal turning as well as external turning?
Yes. The CNMG190616 AH6225 insert is indicated for both external and internal turning applications when mounted in a compatible holder.

What determines compatibility with a toolholder?
Compatibility depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness; the ISO specification ensures broad holder availability for the CNMG190616 geometry.

What is the corner radius and how does it affect performance?
The corner radius is 1.6 mm; this radius improves edge strength and vibration damping compared with smaller radii, supporting stable cutting and longer tool life in medium-turning operations.

What are the chip control features of this grade?
The plate is equipped with a double-sided chipbreaker and a cylindrical hole for secure clamping; the chipbreaker is designed to promote controlled chip formation when machining stainless steel.
