CNMG090304 AH6225 indexable insert for turning (Tungaloy)

The CNMG090304 AH6225 is an ISO rhombic turning insert designed for external and internal turning of stainless steels, offering a sharp yet stable cutting edge for medium machining and variable conditions

• ISO CNMG090304 geometry, 80° included angle
• PVD-coated AH6225 carbide grade
• Optimised for stainless steel machining
• Double-sided chipbreaker, rhombic insert

Reliable geometry for consistent chip control and repeatable results

The ISO CNMG090304 geometry combines an 80° included angle with a rhombic outline and a 0° clearance to give rigid seat and reliable cutting orientation. This layout enhances tool stability during lateral and axial cutting, which translates into reduced vibration and more consistent surface finishes. The double-sided chipbreaker supports controlled chip formation across a range of feeds, lowering the frequency of manual interventions and contributing to uninterrupted production cycles. Such geometry is particularly beneficial in mixed-batch environments where repeatable results are essential.

Advanced grade and coating for stainless steel performance

The insert’s AH6225 grade is a PVD-coated carbide designed as a universal solution for stainless steel applications, balancing a sharp cutting edge with sufficient chipping resistance. The PVD layer increases wear resistance and reduces the tendency for built-up edge formation, which often jeopardises surface integrity when machining work-hardenable alloys. As a result, operators obtain steadier tool life and a better-quality component finish under medium cutting conditions, while tool change intervals are stabilised — a tangible contribution to productivity and cost-efficiency.

Practical compatibility and handling advantages for workshop workflow

With a 3.18 mm plate thickness, 0.4 mm corner radius and a rhombic 09 size, the insert fits standard ISO holders when matched by form, clearance, tolerance class and fastening method. The cylindrical hole enhances secure clamping and positional repeatability, while the double-sided design effectively doubles available cutting edges per seat. For procurement and inventory planning, the manufacturer SKU TUN6903154 and article number 6903154 identify the genuine component; technical support and selection guidance are available through Metav Werkzeuge to ensure the chosen chipbreaker and grade match the specific material and stability conditions of the operation.

FAQ

What materials is this insert suited for? The CNMG090304 AH6225 insert is optimised for machining stainless steel; the AH6225 PVD-coated carbide grade reduces built-up edge and improves wear resistance during medium cutting.

What are the key geometric specifications to check for holder compatibility? Compatibility depends on form, clearance, tolerance class, fastening, size and thickness; the CNMG090304 uses a rhombic 09 size, 3.18 mm thickness and 0° clearance which should be matched to ISO holders.

How does the AH6225 grade affect tool life and surface finish? The AH6225 grade provides a sharp yet stable cutting edge with a PVD coating that enhances wear resistance and lowers built-up edge, resulting in steadier tool life and improved surface quality under typical stainless steel conditions.

Is this insert reversible and how does that impact cost-efficiency? The double-sided chipbreaker design allows the insert to be indexed for additional cutting edges, effectively increasing usable life per insert and reducing tooling cost per component.

Which identifiers should be used when ordering the original part? Order using the manufacturer article number 6903154 or the SKU 6903154-Tungaloy to ensure the genuine Tungaloy indexable insert is supplied.
