CNMG 120404 T9215 Wendeplatten - Tungaloy

Take advantage of the combination of CVD-coated cemented carbide wear resistance, the 0.4 mm corner radius for precise finishes, and reliable double-sided chip control to keep turning operations productive and predictable; order the CNMG120404 T9215 insert directly via Metav Werkzeuge or ask our consultants if needed.

CNMG 120404 T9215 ISO indexable turning insert — rhombic 80° geometry, CVD-coated

The CNMG 120404 T9215 is an ISO-standard rhombic indexable insert designed for external and internal turning in medium-steel machining.

• CVD-coated cemented carbide for wear resistance
• Rhombic 80° geometry for versatile turning
• Double-sided chipbreaker for consistent chips
• 4.76 mm thickness with cylindrical hole for secure mounting

Boosted productivity for medium-steel turning

The insert is manufactured from CVD-coated cemented carbide, a coating-substrate system that offers a balance of high wear resistance and fracture toughness, making it particularly well suited to continuous and lightly interrupted turning of medium-strength steel. This results in consistent tool life and fewer unscheduled tip changes, which improves machine uptime and lowers cycle-time variability. The combination of coating and substrate is engineered for reliable performance under typical workshop feeds and speeds, delivering an efficient wear profile rather than abrupt failure.

Stable chip formation and surface quality

A double-sided chipbreaker combined with the rhombic 80° geometry ensures controlled chip evacuation and a stable cutting edge contact. For operators less familiar with insert micro-geometry: the chipbreaker redirects and fragments chips so they do not entangle or damage the workpiece, which helps to secure repeatable surface finish and reduces the risk of workpiece rework. The 0° clearance and the specified 0.4 mm corner radius support edge strength and predictable cutting forces, which contributes to improved dimensional stability on turned components.

Designed for easy integration and repeatable results

This insert conforms to ISO norms for indexable turning plates, so compatibility with holders depends on form, free angle, tolerance class, fastening, size and thickness. The 4.76 mm thickness, 12 mm size, and cylindrical hole allow secure clamping in standard CNMG-capable toolholders; the double-sided design doubles service life per insert. For production planning, the part number and manufacturer SKU facilitate ordering and inventory: the insert is supplied as an ISO-series component intended for a system that includes a matched holder, shim and clamping set. The result is reduced setup time and a predictable process window that supports consistent batch production.

FAQ

What materials is this insert intended for? The CNMG120404 T9215 insert is optimised for medium-steel machining thanks to its CVD-coated cemented carbide grade, offering an effective balance of wear resistance and edge robustness.

Can the insert be used for interrupted cuts? Yes, the T9215 grade is suitable for continuous to lightly interrupted cuts; its fracture-resistant substrate supports stable performance under slight interruptions.

How does the chipbreaker affect machining? The double-sided chipbreaker on this insert promotes consistent chip formation and evacuation, which contributes to stable cutting forces and improved surface quality on turned parts.

Is this an ISO-standard insert and how does that help? The insert conforms to ISO indexable turning plate standards (designation CNMG120404), enabling compatibility with standard CNMG toolholders when form, clearance, tolerance class, fastening, size and thickness match.
