Stable performance under variable cutting conditions

The T9225 grade is a CVD-coated carbide designed for reliability in changing engagement and slightly interrupted cuts. Its formulation delivers a balance of toughness and wear resistance, reducing the risk of premature edge failure when operations vary between stable and intermittent contact. For production environments where consistency matters, this insert maintains cutting-edge integrity while preserving dimensional accuracy and surface quality.

Enhanced edge strength and surface finish for interrupted turning

With a 1.2 mm corner radius and a double-sided chipbreaker, the insert improves edge strength and chip control during heavier passes. The corner radius increases resistance to mechanical shock, which is particularly beneficial for interrupted cuts and modest overhangs. As a result, cycle times can be optimised through more reliable cutting parameters and fewer unplanned tool changes, contributing to a smoother workflow and predictable machining results.

Secure clamping and ISO compatibility explained

Designed to the ISO series of indexable turning plates, the geometry and the cylindrical hole guarantee consistent fitment to matching holders. Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; these parameters ensure a secure connection between insert and holder, minimising micro-movements that can degrade finish. Choosing the correct holder and torque for the screw secures repeatable seating and extends insert life.

Material versatility and production economy

The hardmetal substrate and CVD coating offer a cost-effective solution across a broad range of steels, making the insert suitable for many workshop and production tasks. The universal character of the grade reduces the need for multiple specialised grades, simplifying tool inventory and accelerating setup. When combined with correct cutting data, the result is improved productivity and lower total tooling cost per part, while preserving machining quality.

FAQ

What applications is this insert intended for? The Tungaloy VNMG160412 T9225 insert is intended for external and internal turning, especially in medium to heavy steel machining and situations with slightly interrupted cuts.

How does the T9225 grade differ from other grades? T9225 is a robust universal CVD-coated carbide grade that emphasises toughness for variable engagement and interrupted cutting, offering a compromise between wear resistance and edge strength.

Which corner radius is available and why does it matter? This insert has a 1.2 mm corner radius, which increases edge strength and improves resistance to mechanical shock, benefiting interrupted operations and enhancing surface finish.

Is the insert compatible with standard ISO holders? Yes, the VNMG160412 follows ISO dimensions; compatibility with a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness to ensure secure seating.

Can this insert handle prolonged heavy cuts? As a universal robust grade, the insert performs well in medium to heavy cutting; however, cutting data and machine stability should be adjusted to application specifics to maximise tool life and process safety.
