CNMG 090304 AH6225 Wendeplatten - Tungaloy
Take advantage of a proven ISO geometry combined with a PVD-coated AH6225 grade to maintain production stability and surface quality when machining stainless steels; the sharp yet robust cutting edge and double-sided chipbreaker reduce changeovers and help sustain throughput — order the insert directly via Metav Werkzeuge or consult its specialists for application support. 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.

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.

Why indexable inserts are indispensable in modern machining
Indexable inserts, also known as cutting inserts or indexable cutting inserts, are standardised, replaceable cutting elements that mount on tool holders such as turning bits, milling cutters or drills. Made from wear-resistant materials like carbide, cermet, ceramic or other superhard grades, they carry the actual cutting edge and allow a worn corner to be rotated or flipped instead of replacing or regrinding the entire tool body.
How these inserts work and when to choose them
In everyday workshop and production settings, indexable inserts perform the direct material removal on the workpiece. Standard inserts for tool systems without internal coolant typically feature closed faces or a single central fixing hole, with heat evacuation handled by external machine nozzles. Inserts designed for systems with internal coolant are engineered to support coolant flow: they include calculated chipbreaker geometries that guide an internal coolant jet under the chip or, in specialised designs, contain sintered microchannels to direct coolant right to the cutting edge. Such coolant-compatible inserts are essential for machining heat-resistant alloys, heavy cutting operations and deep internal machining, where thermal load and chip control are critical.
Tangible benefits for production and workshop efficiency
Choosing the right indexable inserts delivers measurable operational advantages:
- Reduced downtime: faster changeover because a worn insert is simply indexed rather than the whole tool being replaced.
- Extended cutting-edge life: targeted coolant application and optimised chipbreaker design lower thermal stress and improve tool life.
- Consistent part quality: predictable cutting-edge geometry from standardised inserts maintains tolerances across batches.
- Versatility: availability in carbide, cermet, ceramic and superhard grades permits selection according to workpiece material and cutting conditions.
- Lower tooling costs over time: fewer full-tool replacements and less regrinding required.

Quick summary
Indexable inserts (cutting inserts or indexable cutting inserts) enable economical, repeatable material removal by allowing worn cutting edges to be indexed or replaced quickly; coolant-adapted designs further reduce thermal load and enhance chip control for demanding applications.
FAQ
What materials are indexable inserts available in?
Indexable inserts are available in wear-resistant grades such as carbide, cermet, ceramic and other superhard materials, selected according to the workpiece material and cutting conditions.
When should I choose inserts with internal coolant support?
Choose inserts designed for internal coolant when machining heat-resistant alloys, performing heavy cuts or working in deep internal features, because the coolant reduces thermal load at the cutting edge and actively improves chip breakage.
How do chipbreaker geometries affect performance?
Chipbreaker geometries on indexable inserts guide the chip flow and, when matched to an internal coolant jet, direct the coolant under the chip to control temperature and facilitate reliable chip formation, which extends edge life and stabilises machining.
Can standard inserts be used with external coolant only?
Yes; standard inserts for tool systems without internal coolant typically have closed faces or a central fixing hole and rely on external machine nozzles for heat evacuation, which is sufficient for many routine, accessible cuts.
Why source inserts through Metav?
Metav supplies a broad range of indexable inserts and tooling, backed by decades of expertise and a comprehensive European stock, making it a practical choice for consistent quality and dependable delivery.
