CNMG120404 T9215 – Rhombic turning insert for medium steel turning by Tungaloy

CNMG120404 T9215 presents an ISO‑standard rhombic insert designed for turning operations, optimised to balance wear resistance and fracture toughness for productive machining of medium steels.

• CVD-coated carbide grade T9215
• 80° rhombic insert geometry
• 0.4 mm corner radius
• Double-sided chipbreaker design
• ISO 120404 compatibility

Enhanced productivity through wear-resistant grade and coating

The T9215 grade, delivered as a CVD-coated carbide substrate, is selected specifically for medium steel applications where a combination of wear resistance and fracture toughness is required. This composition reduces flank and crater wear over extended production runs and supports higher metal removal rates under stable cutting conditions. By choosing a grade engineered for continuous to slightly interrupted cuts, manufacturers can expect fewer insert changes and more consistent cycle times, improving overall line efficiency and component throughput.

Geometry that secures part quality and process stability

The 80° rhombic geometry combined with a 0.4 mm corner radius provides a reliable compromise between edge strength and part finish. The rhombic form enables both external and internal turning profiles while the modest corner radius helps absorb impact at entry and exit points, lowering the risk of chipping. The double-sided chipbreaker contributes to predictable chip formation and evacuation, which supports repeatable surface integrity and reduces secondary operations. These features translate into fewer rejects and a steadier process window for batch production.

Straightforward integration into ISO tool systems

As an ISO‑standard insert, compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness. The CNMG120404 is supplied with a cylindrical hole and a plate thickness of 4.76 mm, allowing installation in a wide range of established external holders and boring bars that accept ISO 120404 inserts. The ISO-standard designation simplifies tool inventory and replacement planning, so adaption into existing tool packs is rapid and predictable. If uncertainty remains about holder matching, technical consultation is recommended to verify form and tolerance alignment.

Application guidance for consistent results

This insert is optimised for continuous to slightly interrupted cuts in medium steel and performs best when paired with a matching chipbreaker and cutting data tuned to the grade’s capabilities. The CVD coating improves thermal resistance and adhesion at the cutting edge, making the insert tolerant to elevated cutting temperatures typical of high‑productivity turning. Expect improved tool life and stable edge behaviour when operations avoid severe interruptions and use appropriate coolant or cutting‑fluid strategies. For complex material mixes or unusual geometries, select the chipbreaker and holder to match stiffness and stability requirements.
