CNMG120412 T9225 — ISO turning insert, CVD-coated cemented carbide, 80° rhombic by Tungaloy

The CNMG120412 T9225 is an ISO rhombic turning insert designed for medium to heavy steel turning, combining a robust universal grade with a double-sided chipbreaker for versatile machining.

• CVD-coated carbide for high wear resistance
• Robust universal grade T9225 for steel turning
• 80° rhombic geometry with 1.2 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Reliable performance under varying cutting conditions

The combination of a CVD-coated cemented carbide substrate and the T9225 grade delivers a balance of toughness and wear resistance suited to fluctuating engagement and slightly interrupted cuts. The coating enhances resistance to abrasive wear and thermal loading, while the substrate maintains edge strength; together these characteristics reduce premature flank wear and lower the frequency of index changes. For production runs where tool life and predictable performance matter, this configuration helps to maintain surface quality and process stability.

ISO compatibility and secure clamping reduce set-up risk

Designed to the ISO designation, the insert matches standard holders when shape, relief angle, tolerance class, clamping method, size and thickness align. The 80° rhombic geometry and 0° relief angle support common CNMG-style holders, and the cylindrical hole provides reliable location for clamping systems. Clear identification of these parameters streamlines tooling selection and minimises set-up downtime, allowing straightforward integration into existing turning tool assemblies without bespoke adapters.

Improved efficiency through geometry and chip control

The double-sided chipbreaker and 1.2 mm corner radius are engineered to combine mechanical strength with effective chip formation for medium-to-heavy steel applications. The chipbreaker helps produce short, manageable chips under varying depths of cut, improving swarf handling and reducing the risk of re-cutting. The relatively large corner radius increases edge security and allows slightly higher feed rates where component geometry permits, contributing to improved metal removal rates and fewer insert changes during production.

FAQ

What materials is this insert suitable for? The CNMG120412 T9225 insert (Tungaloy turning insert, SKU 6780929-Tungaloy) is intended primarily for medium to heavy steel turning, offering the toughness required for variable engagement and slightly interrupted cuts.

How does the T9225 grade perform in interrupted cuts? The T9225 grade combines toughness with wear resistance, making it well suited to operations with changing cutting conditions or light interruptions where chipping risk is present.

Which toolholders are compatible with this insert? Compatibility is determined by geometry and dimensions; the 80° rhombic form, 0° relief and ISO 120412 sizing make the insert suitable for standard CNMG-style external turning holders that accept ISO rhombic plates.

Is the insert indexable and reversible? Yes, the insert is double-sided with a chipbreaker on each usable edge, allowing indexing to the next edge and efficient use of all available cutting corners.

What should be considered when selecting cutting data for this insert? Cutting parameters depend on workpiece material, machine rigidity and holder stability; the chipbreaker and 1.2 mm corner radius favour moderate to heavy feeds while supporting edge security in steel turning.
