CNMG090404 T9225 — CNMG 090404 turning insert, ISO rhombic, 80° by Tungaloy

The CNMG090404 T9225 is an ISO rhombic indexable insert for external and internal turning, engineered for medium to heavy steel machining where interrupted cuts demand toughness.

• CVD-coated carbide grade T9225
• 80° rhombic insert for stable turning
• 0.4 mm corner radius for fine finishing
• Double-sided chipbreaker, with cylindrical hole

Consistent performance under variable cutting conditions

The combination of a CVD-coated cemented carbide substrate and the T9225 grade gives a balance of hardness and toughness intended for medium to heavy steel machining. The coating reduces flank wear and improves edge stability under changing engagement conditions, while the substrate maintains resistance to chipping during light interruptions. This results in consistent cycle times and reduced reject rates, supporting a more predictable production flow and lower process variation.

Precision geometry for reliable surface quality

An 80° rhombic form with a 0.4 mm corner radius delivers a compromise between strength and finishing capability: the larger approach angle gives improved cutting-edge support for heavy cuts, while the modest radius enables finer surface finishes where required. The plate thickness of 4.76 mm and the central cylindrical hole ensure secure clamping in standard CNMG-compatible holders. The insert’s double-sided chipbreaker aids controlled chip formation, lowering the risk of built-up edge and promoting consistent surface integrity on turned components.

Easy integration into ISO turning systems

As an ISO-format indexable plate, the CNMG090404 designation denotes compatibility with a wide range of external holders and boring bars when the holder matches the insert’s shape, relief angle, tolerance class, fastening method, size and thickness. Check holder specifications for the 80° rhombic form and the 0° relief to ensure correct seating and clamp engagement. Proper matching reduces axial runout and vibration, which in turn extends effective tool life and improves repeatability across batches.

Where the insert adds most value on the shop floor

This insert is particularly suitable for operations requiring robustness under intermittent cuts or variable engagement—typical scenarios in roughing and mixed finish/roughing cycles. Use of the T9225 grade supports broad material coverage and stable chip formation, which helps maintain productivity in flexible production environments. For setups where tool-change frequency and process stability affect throughput, selecting this ISO indexable plate helps to reduce downtime and contributes to predictable per-part machining costs.

FAQ

Which materials is this insert best suited for?

The CNMG090404 T9225 insert is formulated for medium to heavy steel machining where a tougher grade is preferred for interrupted cuts and variable engagement.

How is the insert secured in a holder?

Compatibility depends on matching the insert’s form, relief angle, tolerance class, fastening method, size and thickness; the CNMG090404 uses a cylindrical central hole and is clamped in CNMG-compatible external holders or boring bars.

Can the insert be used for finishing operations?

Yes, with its 0.4 mm corner radius the plate can achieve fine surface finishes when applied with appropriate feeds and speeds; the geometry also supports heavier cuts when needed.

Is the CNMG090404 indexable on both sides?

The plate is double-sided with a chipbreaker on both faces, enabling one index for a fresh cutting edge and thus improved economy per insert.
