CNMG 120404 T9215 turning insert by Tungaloy — ISO rhombic insert, 80° geometry

The CNMG 120404 T9215 is an ISO-standard rhombic, double-sided turning insert designed for external and internal turning in medium steel, offering a CVD-coated carbide grade tailored for productive, continuous to slightly interrupted cuts

• CVD-coated cemented carbide grade T9215
• 80° rhombic geometry for robust engagement
• 0.4 mm nose radius for mixed finishing and roughing
• Double-sided insert with cylindrical hole

Higher throughput with a wear-resistant CVD-coated grade

The T9215 grade combines CVD coating and a specifically engineered carbide substrate to deliver extended tool life under typical mid-range steel cutting conditions. This material pairing increases resistance to abrasive wear while maintaining fracture toughness, so machining intervals can be extended without compromising component quality. For manufacturers focused on efficient batch production, the result is reduced tool-change frequency and steadier cycle times, which directly supports predictable throughput and lower operational overhead.

Secure clamping and versatile compatibility for reliable turning

The insert’s ISO designation and rhombic form ensure compatibility with standard external holders, boring bars and tooling systems, provided that form, clearance angle and tolerance class match. The 80° cutting angle and 0° relief create a stable cutting geometry that tolerates moderate radial engagement and interrupted cuts. The central cylindrical hole supports positive clamping systems and replacement screws, enabling quick index changes and reproducible positioning — a practical advantage in production environments where setup time and repeatability matter.

Practical handling and application guidance for process stability

With a 4.76 mm plate thickness and double-sided configuration, the insert offers two cutting edges per index, lowering cost per edge and simplifying inventory management. The 0.4 mm nose radius permits a balance between surface finish and tool life: select lighter feeds for improved finishes or increase feed for higher material removal while retaining process security. For turning tasks in medium steel, the T9215 grade is suited to continuous to slightly interrupted cuts; choose a chipbreaker and cutting parameters aligned with workpiece rigidity and machining strategy to benefit fully from the grade’s wear and fracture properties.

FAQ

What materials is this insert best suited for?
The CNMG 120404 T9215 insert is optimised for medium steel machining; the CVD-coated cemented carbide grade combines wear resistance with fracture toughness for productive turning operations.

How does the insert’s geometry affect stability in interrupted cuts?
The 80° rhombic geometry and 0° relief angle of the CNMG 120404 provide a robust cutting edge that tolerates moderate interruptions, improving process stability in less continuous cuts.

Can this insert be clamped in standard ISO holders?
Yes, the ISO designation and cylindrical hole enable secure clamping in compatible external holders and boring bars when form, free angle and tolerance class match the holder specification.
