• Robust for medium to heavy steel machining
• 1.2 mm corner radius, cylindrical hole

Reliable cutting performance under variable conditions

The T9225 composition is a CVD-coated carbide designed as a universal, robust grade for medium-to-heavy steel turning. This combination of coating and substrate increases resistance to flank wear while maintaining toughness under slightly interrupted cuts, which translates into fewer unplanned tool changes and more predictable production cycles. The coating promotes stable chip formation, reducing the risk of edge build-up and helping to preserve component surface quality throughout a production run.

Geometry that reduces set-up time and improves stability

The rhombic 80° geometry and the 0° clearance angle mean the insert is compatible with a wide range of ISO holders; the cylindrical hole ensures secure fastening and precise seating. A 1.2 mm corner radius balances edge strength and surface finish: larger radii increase edge durability and vibration resistance, while this radius still permits fine surface results on turned faces. Together, these geometric characteristics simplify tool selection and shorten set-up procedures in mixed production environments.

System advantages for predictable shop-floor productivity

As an ISO-standard indexable insert, this component forms part of a complete cutting system: insert, suitable external holder or boring bar, support shim and clamping screws. The single-sided chipbreaker matches the grade and workpiece demands to ensure controlled chip flow during both external and internal turning operations. Choosing this insert reduces tool-stock complexity and supports a cost-effective machining strategy by combining a universal cutting grade with geometry that suits many common turning tasks.
