CNMG090404 T9215 CNMG turning insert by Tungaloy — ISO turning insert for medium steel

CNMG090404 T9215 Tungaloy insert provides a reliable solution for external and internal turning in medium steel, combining wear resistance and fracture toughness for continuous to slightly interrupted cuts.

• CVD-coated cemented carbide grade T9215
• Rhombic form with cylindrical hole
• Double-sided chipbreaker for stable chips
• 0.4 mm corner radius for fine finishing

Consistent chip control for efficient production

The combination of a double-sided chipbreaker and CVD coating ensures consistent chip formation under varying cutting conditions, which reduces cycle-time variability and helps maintain stable machining parameters. The coated cemented carbide substrate offers enhanced wear resistance and thermal stability, so the cutting edge retains geometry over longer runs; for batch processing this means fewer tool changes and more predictable throughput. Compatibility with ISO holders simplifies stocking and program transfer between machines.

Robust cutting edge to extend tool life

A small but decisive 0.4 mm corner radius and the T9215 grade deliver a balance between edge strength and surface finish. The insert’s design focuses on resisting flank wear and chipping during the moderate interruptions common in component turning; this translates into longer effective edge life and lower tooling consumption per part. The 80° approach angle supports a stable cutting force direction, reducing vibration and improving repeatable surface quality when machining medium steel.

Easy integration and predictable inventory handling

The ISO designation and standardised dimensions (size 09, thickness 4.76 mm) allow straightforward replacement and interchangeability across holders that accept CNMG inserts with a cylindrical hole. The presence of a central hole and standard tolerance class means clamping and location are reproducible, which reduces setup time and the risk of mounting errors. For shops managing multiple machine types, this standardisation supports consistent process documentation and tool management.

Application guidance and material suitability

Designed primarily for turning applications, the insert performs best in medium steel where a combination of wear resistance and toughness is required. The T9215 grade is aimed at productive machining at continuous to slightly interrupted cuts, rather than heavy interrupted or abrasive applications. For modifications to cutting data or to confirm suitability for specific alloys and cutting conditions, consult technical data sheets or request tailored advice from Metav Werkzeuge to optimise feed and speed settings for the required surface finish and tolerance.

FAQ

Is this insert suitable for internal turning operations?
Yes. The CNMG090404 T9215 Tungaloy insert is designed for both external and internal turning; the rhombic form and central cylindrical hole allow reliable clamping in appropriate ISO holders.

What material is the cutting substrate and what coating is used?
The insert uses a cemented carbide substrate with a CVD coating, the combination of which provides wear resistance and toughness suitable for medium steel machining.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius balances edge strength and finish quality; with appropriate feeds it delivers good surface integrity while resisting edge chipping during continuous to lightly interrupted cuts on medium steel.

Can the insert handle interrupted cuts?
The T9215 grade is intended for continuous to slightly interrupted cutting; heavier interruptions may require a different grade or a larger corner radius to avoid premature edge failure.

Which holders are compatible with this insert form?
Compatibility is determined by the insert form, relief angle, tolerance class, clamping style, size and thickness; the ISO-form CNMG090404 fits standard holders that accept CNMG inserts with a cylindrical hole.
