CNMM 250924 T9215 indexable turning insert for turning – Tungaloy

A CNMM250924 indexable insert in a rhombic form designed for general turning applications, offering an 80° included angle and optimised grade for medium-steel machining.

• ISO rhombic insert CNMM250924, 80° geometry
• CVD-coated carbide grade T9215 for medium steel
• 2.4 mm corner radius for robust edge life
• Cylindrical hole, 9.52 mm thickness for secure clamping

Consistent performance for medium-steel machining

The combination of CVD-coated carbide and the T9215 grade delivers a balance between wear resistance and edge toughness that suits medium-steel applications. The insert’s material and coating are selected to extend tool life under continuous and lightly interrupted cutting conditions, improving process stability and reducing unplanned tool changes. This results in a more predictable machining rhythm and supports higher throughput in production environments.

Geometry and clamping that support reliable production

The 80° geometry and rhombic shape provide a versatile cutting profile for both external and internal turning. A 2.4 mm corner radius gives a durable cutting edge that resists chipping under moderate feed and depth of cut, while the cylindrical hole and 9.52 mm plate thickness ensure secure clamping in compatible holders. Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness, so pairing with the correct outer holder or boring bar is essential for repeatable results.

What the coating and substrate mean in practice

A CVD coating on a carbide substrate creates a hard, wear‑resistant surface that reduces flank wear and maintains cutting-edge geometry for longer. The carbide body provides the necessary substrate toughness; combined with the coating, it allows sustained cutting performance and consistent surface finish on steel. For production planning, this means fewer insert changes and a lower rate of edge-related scrap when operating within recommended cutting parameters.

Application guidance and process benefits

Designed for turning operations, the insert is suitable for external and internal turning where a single-sided chipbreaker matches the workpiece material and machining stability. Selecting the correct chipbreaker and grade for the job helps to manage chip formation and evacuation, improving surface integrity and reducing cycle times. The overall design supports more efficient material removal, contributing to a higher productivity rate and a more economical process per part produced.

FAQ

Which holders are compatible with this insert?
Compatibility is determined by the holder’s form, clearance angle, tolerance class, fastening method, size and plate thickness; the CNMM250924 insert requires an ISO-compatible rhombic external holder or boring bar designed for inserts with a cylindrical hole.

Is this grade suitable for interrupted cuts?
The T9215 grade is optimised for continuous to light interrupted cuts; it balances wear resistance and toughness to perform well under modest interruption without excessive edge chipping.

What materials is this insert intended for?
This insert is primarily intended for medium-steel machining; the CVD coating and carbide substrate provide the wear resistance and toughness required for this material group.

How does the 2.4 mm corner radius affect cutting?
A 2.4 mm corner radius enhances edge robustness, improves tool life under higher feed or depth of cut and can help produce a consistent surface finish when feeds and speeds are set accordingly.

Can this insert achieve high productivity?
Yes, the combination of CVD-coated carbide and the T9215 grade supports higher cutting volumes with stable performance, making the insert suitable for productive turning operations.
