CNMG 090402 T9215 Tungaloy – ISO turning insert with CVD‑coated carbide, rhomboid form, 0° relief

CNMG 090402 T9215 is an ISO‑standard turning insert designed for medium steel machining and compatible ISO holders; its rhomboid form and cylindrical hole ensure secure clamping and repeatable positioning.

• CVD‑coated carbide grade T9215
• 0.2 mm corner radius
• Double‑sided chipbreaker
• ISO CNMG compatibility

High throughput with controlled wear for medium steel

The CVD‑coated carbide composition of the T9215 grade delivers a robust combination of wear resistance and fracture toughness that is particularly suited to medium steel applications. The coating reduces flank and crater wear under continuous to lightly interrupted cuts, which translates into longer effective tool life and fewer index changes. Specifying an insert with a 0.2 mm corner radius helps maintain dimensional stability on external profiles while balancing edge strength; this trade‑off supports higher feed rates without sacrificing surface integrity. The overall result is a measurable improvement in machining consistency and productivity when replacing conventional uncoated or lower‑grade inserts.

Secure fit and ISO compatibility to reduce downtime

Belonging to the ISO turning insert series, the CNMG 090402 geometry is defined so that compatibility with the toolholder depends on form, relief angle, tolerance class, clamping method, size and thickness. The rhomboid plate shape and the cylindrical centre hole provide reliable clamping and repeatable indexing in matched CNMG holders or boring bars. With a plate thickness of 4.76 mm and a nominal included angle of 80°, the insert sits stably in the pocket, reducing chatter and facilitating predictable wear patterns. Clear fitment standards lower the risk of incorrect assembly and shorten tool changeover times, contributing to smoother process flow on the shop floor.

Optimised chip control for continuous productivity

The double‑sided chipbreaker geometry is engineered to support effective chip formation and evacuation during routine turning operations. Good chip control reduces the likelihood of built‑up edge and workpiece marking, improving first‑pass quality and reducing rework. For continuous machining or light interruptions, the combination of the insert’s geometry and the T9215 grade maintains cutting stability, enabling longer uninterrupted runs and higher overall throughput. By reducing unexpected stops for edge changes and managing swarf more consistently, the insert helps maintain planned cycle times and labour efficiency.

Grade and coating in plain terms

The designation T9215 indicates a CVD‑coated carbide grade optimised for a wide range of steels; the coating provides a hard, heat‑resistant surface while the substrate retains core toughness, which helps prevent premature fracture under higher feed or interrupted cuts. The 0° relief means the insert is manufactured for neutral clearance suited to many turning setups; paired with the rhomboid CNMG shape, it supports both external and internal turning tasks when used with matching holders. For customers less familiar with coating technologies: CVD (chemical vapour deposition) creates a uniform, adherent layer that increases resistance to abrasive wear and thermal degradation, extending edge life in demanding production environments.

FAQ

What materials is this insert intended for?
The CNMG 090402 T9215 insert is optimised for medium steel machining; the T9215 CVD‑coated carbide grade balances wear resistance and toughness for continuous to slightly interrupted turning operations.

Will this insert fit existing CNMG holders?
Compatibility is determined by form, relief angle, tolerance class, clamping method, size and thickness; the CNMG090402 geometry matches standard CNMG toolholders when the pocket is specified for ISO CNMG inserts.

What advantages does the T9215 coating provide?
The CVD coating on the T9215 grade improves resistance to flank and crater wear and supports higher productivity by maintaining edge condition longer under elevated temperatures typical of continuous steel cutting.

How does the double‑sided chipbreaker affect use?
A double‑sided chipbreaker allows effective chip control on both usable faces of the insert, enhancing swarf management and surface finish during routine turning cycles.

Is the corner radius suitable for profile turning?
The 0.2 mm corner radius offers a compromise between edge strength and fine profile definition, making it suitable for many external turning profiles where a moderate radius is required.
