Maximise productivity for medium‑steel turning

The CVD‑coated carbide composition of this insert delivers a favourable balance between wear resistance and fracture toughness, making it a strong choice for productive turning of medium steel. The T9215 grade is engineered to maintain cutting-edge integrity during continuous operations and light interruptions, which translates directly into longer tool life and fewer indexings. This results in lower downtime and improved throughput on series and batch work where consistent performance is essential.

Consistent geometry for faster set‑up and interchangeability

Built to ISO dimensions, the rhombic insert form and the defined 80° geometry simplify holder selection and replacement. Compatibility is determined by shape, clearance, tolerance class, fastening and thickness, so using ISO‑compliant inserts reduces set‑up time and avoids ambiguity at tool changes. The presence of a cylindrical central hole and standard thickness of 4.76 mm supports secure clamping and repeatable positioning, which is particularly valuable for automated or multi‑station tooling arrangements.

Improved chip control and protected cutting edge

The double‑sided chipbreaker is designed to promote stable chip formation under typical turning parameters for steels; this supports safer evacuation and reduces risk of re-cutting. The 0.4 mm corner radius offers a robust edge that resists chipping while still allowing acceptable surface finish in many applications. Where surface integrity is critical, the corner radius and chipbreaker should be matched to workpiece stability and feed rate to achieve the desired balance between finish and tool life. The insert’s 0° clearance helps maintain predictable contact geometry with the workpiece.

Practical selection advice for everyday workshop use

Select the chipbreaker and grade to suit material, cut stability and the expected interruption level: the current specification is a first choice for standardised medium‑steel conditions. The insert is suitable for both external and internal turning when used with the appropriate holder and backing plate; a rigid set‑up will optimise life and part tolerances. For customers requiring further machining parameters or matching to specific holders, Metav Werkzeuge offers application guidance to align the insert characteristics with process requirements.

FAQ

What steels is this insert best suited to?
The T9215 grade in this CNMG090404 insert is optimised for medium steel machining, offering a balance of wear resistance and toughness suitable for productive continuous to light interrupted turning.

Is the insert reversible and how many cutting edges are available?
The insert is double‑sided with a rhombic form, providing multiple usable edges; the double‑sided chipbreaker supports repeated indexing.

How does the geometry affect holder compatibility?
Being ISO‑compliant, the insert’s form, clearance angle and size permit compatibility with standard CNMG holders when the holder matches the ISO specifications.

Can this insert handle interrupted cuts?
Grade T9215 is suitable for continuous and slightly interrupted cuts; severe interruptions require assessment of cutting conditions and may need a more robust grade or modified parameters.

What does the 0.4 mm radius mean for surface finish?
A 0.4 mm corner radius increases edge strength and reduces chipping risk while still producing acceptable surface finish; finer radii give better finish but lower edge robustness.
