CNMG 120404 T9215 indexable turning insert for turning, CVD-coated carbide, 0.4 mm – Tungaloy

CNMG 120404 T9215 is an ISO‑standard indexable insert designed for external and internal turning in medium steel, offering robust wear resistance and reliable chip control in continuous to slightly interrupted cuts

• CVD-coated carbide grade T9215
• 0.4 mm corner radius for precision
• Rhombic CNMG 80° geometry
• Double-sided chipbreaker, cylindrical hole fitting

Higher throughput through wear-resistant coating and grade

The T9215 grade combines a CVD-coated surface with a wear-resistant carbide substrate to extend tool life under production conditions. This composition provides a balanced combination of abrasion resistance and fracture toughness that supports higher cutting speeds and longer tool cycles. For workshops aiming to reduce changeover frequency and improve cycle time, the coated substrate helps lower total machining costs by maintaining consistent performance over extended runs.

Secure mounting and ISO compatibility for straightforward integration

Compatibility with standard ISO holders is ensured by the insert’s CNMG form, dimensional tolerances and a cylindrical through-hole for secure clamping. The geometry includes a 0° relief angle and an 80° main cutting angle, enabling predictable engagement with common external holders and boring bars. This results in stable cutting forces and reproducible positioning, which simplifies tool inventory management and reduces setup variability on the shop floor.

Precision finishes and effective chip control for medium steel

The 0.4 mm corner radius delivers repeatable edge strength while allowing fine surface finishes and dimensional control during turning operations in medium steel. The rhombic CNMG shape and double-sided chipbreaker offer two usable cutting edges per side, improving cost-efficiency per insert. Together, these features support consistent chip formation and evacuation, reducing the risk of built-up edge and minimising rework on turned components.

Practical assembly and system considerations for smooth implementation

The insert functions as part of a system comprising the ISO indexable insert, a compatible external holder or boring bar, a shim/clamping set and replacement screws. Selection of the appropriate chipbreaker and grade should follow the workpiece material and machining stability; the T9215 grade is particularly suited to medium steel applications where a balance of wear resistance and toughness is required. For workshop planning, the standard CNMG sizing simplifies matching to existing toolholders and inventory items.
