CNMG120404 T9215 CNMG indexable insert for turning — Tungaloy

The CNMG120404 T9215 is an ISO‑standard CNMG indexable insert engineered for external and internal turning in medium‑grade steels, combining CVD‑coated carbide robustness with a compact 0.4 mm corner radius for versatile production use.

• ISO CNMG geometry, compatible with standard holders
• CVD‑coated carbide T9215 for medium steel
• Double‑sided chipbreaker for stable chip control
• 0.4 mm corner radius for versatile turning

Consistent productivity for medium‑steel turning

The CNMG indexable insert delivers consistent productivity thanks to the CVD‑coated carbide T9215 grade, which balances high wear resistance with good fracture toughness for continuous to slightly interrupted cuts. The coating increases abrasion resistance and thermal stability, reducing flank wear under sustained machining. For production environments where tool life and predictable replacement intervals matter, this combination leads to fewer stoppages and more reliable cycle times while maintaining component tolerances.

Secure clamping and straightforward tool inventory

ISO standardisation of the rhombic CNMG shape, the cylindrical hole and the double‑sided format simplify tool logistics and clamping stability. The insert thickness of 4.76 mm and the nominal size designation ensure compatibility with holders that match form, relief angle and tolerance class. Using a double‑sided insert halves the per‑edge cost in relation to single‑sided alternatives and reduces inventory complexity, while the secure seating afforded by the hole style supports repeatable positioning and consistent surface finish across batches.

Improved chip control and surface quality

The double‑sided chipbreaker is tuned for medium‑steel applications, promoting stable chip formation and efficient evacuation even under higher metal removal rates. Stable chips reduce the load on toolpaths and machine tool components, and the combined effect of an optimised chipbreaker with CVD coating helps achieve improved surface quality and dimensional consistency. For workshops aiming to raise first‑pass yield, this insert offers a practical route to fewer reworks and a steadier process window.

Application guidance and selection tips

Designed primarily for turning operations, this insert suits both external and internal turning when the workpiece material and clamping stiffness are appropriate. Selection of the chipbreaker and cutting parameters should follow the workpiece stability: choose more robust settings for interrupted cuts and finer parameters for precise finishing passes. Compatibility with a holder depends on geometry, relief angle (0° in this case), fastening and size; pairing the insert with the correct external holder or boring bar ensures optimum performance and repeatable results.

FAQ

What materials is this insert best suited for? The CNMG120404 T9215 indexable insert from Tungaloy is optimised for medium‑grade steel machining, offering a balance of wear resistance and toughness suited to continuous and slightly interrupted turning.

Is this insert reversible and how does that affect inventory? Yes, the insert is double‑sided; this CNMG format allows flipping to a fresh cutting edge, effectively halving edge‑related inventory needs compared with single‑edged inserts while maintaining consistent clamping geometry.

How does the T9215 grade influence tool life and performance? T9215 is a CVD‑coated carbide grade that provides high wear resistance with reliable fracture strength, which supports longer tool life and predictable performance during productive turning operations in medium steels.

What does the cylindrical hole contribute to the setup? The cylindrical hole in this CNMG insert ensures secure and repeatable clamping on compatible holders, improving positional accuracy and consistency across multiple index changes when used with the correct fastening hardware.

Which holders or systems are compatible with this insert form? Compatibility depends on holder geometry, relief angle, tolerance class and fastening method; the ISO CNMG form, size 12 and 4.76 mm thickness make the CNMG120404 suitable for standard CNMG external holders and boring bars when matched correctly
