CNMG190612 AH6225 ISO turning insert — PVD-coated carbide, 80° rhombic — Tungaloy

The CNMG190612 AH6225 is an ISO rhombic indexable insert for precision external and internal turning, designed to deliver a balance of cutting-edge sharpness and edge stability in varied machining conditions.

• PVD-coated carbide grade AH6225
• 80° rhombic shape, 19 mm size
• Double-sided chipbreaker, 1.2 mm corner radius
• Cylindrical-hole design for secure clamping

Faster, more consistent cutting with PVD-coated carbide

The combination of a PVD-coated surface and a carbide substrate in grade AH6225 provides a sharp yet robust cutting edge optimised for medium cutting conditions. This balance reduces built-up edge and promotes a predictable wear pattern when machining rostfreie Stähle, which in turn helps stabilise cycle times and surface finish. The coating acts as a thermal barrier and improves adhesion resistance, so the insert sustains performance under variable feeds and speeds without excessive edge rounding.

Reliable chip control and application clarity for turning

Built with a double-sided chipbreaker, the insert manages chip formation for common turning tasks, making it suitable for both roughing and semi-finishing when the correct break geometry is selected. A chipbreaker improves evacuation and reduces spindle load; explained simply, it directs and breaks chips into shorter curls, lowering the risk of entanglement and improving tool life. Use this insert in standard turning toolholders or boring bars compatible with ISO rhombic plates to exploit its chip control benefits.

Secure seating and system compatibility reduce downtime

An ISO-standard geometry plus the cylindrical hole ensure repeatable clamping and quick indexability in a wide range of holders; compatibility depends on form, relief angle, tolerance class, fastening arrangement, plate size and thickness. The 80° approach angle supports a versatile contact geometry that balances radial and axial cutting forces, while the 1.2 mm corner radius offers a compromise between edge strength and surface finish. These aspects make the insert straightforward to integrate into existing tool systems and help reduce set-up time.

Predictable economics through tool-life and process stability

The insert forms part of a system—holder, underlay/clamp set and fastening hardware—to deliver a stable cutting environment and predictable replacement intervals. Favourable wear characteristics of AH6225 can lower the overall cost per part by extending service intervals and maintaining surface quality without constant requalification. For manufacturers seeking reproducible results in serial production, this insert contributes to fewer process interruptions and a steady output quality.

FAQ

What materials is this insert suitable for?
The CNMG190612 AH6225 insert is designed primarily for machining rostfreie Stähle and can be used in varied stainless-steel turning tasks where a sharp, stable cutting edge is required.

What does the AH6225 grade offer compared with general-purpose grades?
AH6225 is a PVD-coated carbide grade optimised for a balance of sharpness and edge stability, delivering improved wear resistance and thermal behaviour in medium machining of rostfreie Stähle.

Is the insert reversible or indexable on both sides?
Yes, the CNMG190612 is double-sided with a chipbreaker on both active edges, permitting indexability to extend service life and reduce tooling costs.

Which toolholders are compatible with this ISO plate?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the insert follows ISO rhombic standards and uses a cylindrical hole for secure clamping.

What cutting geometry is represented by the 80° angle?
An 80° approach angle gives a balanced distribution of radial and axial forces, making the plate versatile for external and internal turning while supporting stable cutting in rostfreie Stähle.

Can this insert be used for finishing passes?
Yes; with appropriate feeds and speeds and depending on the required surface finish, the 1.2 mm corner radius and the AH6225 grade allow semi-finishing and finishing in many rostfreie Stahl applications.
