CNMG120408 T9225 indexable turning insert by Tungaloy — ISO rhombic 80° for turning

CNMG120408 T9225 is an ISO‑standard indexable turning insert designed for external and internal turning, offering a tough, CVD‑coated carbide grade for stable performance under variable engagement conditions

• ISO rhombic CNMG 80° geometry
• CVD-coated carbide grade T9225
• Robust universal grade for medium/heavy steel
• Double-sided insert with cylindrical hole
• 0.8 mm corner radius, 4.76 mm thickness

Reliable performance for demanding steel turning

The CNMG120408 T9225 insert brings together an ISO‑compliant rhombic geometry and a CVD‑coated carbide substrate engineered for the oscillating demands of medium‑to‑heavy steel turning. The combination of grade T9225 and a design optimised for interrupted cuts results in predictable tool life and consistent cutting forces, which reduces cycle time variation in production. Compatibility with standard indexable holders is determined by form, clearance angle and tolerance class, ensuring straightforward integration into existing tool systems while maintaining stable contact and clamping.

Controlled chips and stable cutting for fewer interruptions

Built as a double‑sided insert with a cylindrical hole, the plate enables rapid indexation and economical use of cutting edges. The 0.8 mm corner radius and rhombic form contribute to reliable chip formation and reduced vibration under heavier engagement. For operators unfamiliar with insert terminology: the corner radius softens the cutting edge to distribute load and improve finish, while a double‑sided insert provides two usable edges, lowering tooling cost per part. These characteristics together support enhanced surface quality and extended edge life on structural and alloyed steels.

Process reliability and easy integration into workshop workflows

This indexable plate is part of a system comprising the insert, the matching external holder or boring bar, a support pad or clamp set and spare screws; specifying the correct holder geometry and tolerance class is essential to exploit the grade’s full potential. The carbide substrate with CVD protection resists abrasive wear while preserving edge toughness, making the insert suitable where changing engagement or light interruptions demand resilience. The result is a tool that helps maintain cycle consistency and reduces unscheduled stoppages, supporting higher throughput and lower rework rates.

FAQ

What materials is this insert suitable for?
The CNMG120408 T9225 insert is formulated as a universal, robust grade for medium‑to‑heavy steel machining; the CVD‑coated carbide substrate provides wear resistance suitable for a broad material range including alloyed steels.

How does the double‑sided design affect costs?
A double‑sided indexable plate offers two usable edges per insert, effectively halving the insert cost per cutting edge compared with single‑edged alternatives, improving economy in batch production.

Which cutter holders are compatible with this geometry?
Compatibility depends on holder form, free angle, tolerance class, fastening method, size and thickness; the plate follows ISO CNMG standards, so holders specified for CNMG inserts with a cylindrical central hole are applicable when tolerances match.

What performance benefits does the T9225 grade provide?
The T9225 carbide grade delivers a balance of toughness and wear resistance for interrupted cuts and variable engagements, yielding stable cutting and extended edge life in steel turning.

Is the insert reversible and easy to index?
Yes — the insert is double‑sided with a central cylindrical hole for secure clamping and straightforward indexation in compatible toolholders (SKU 6794544‑Tungaloy).
