CNMG 120408 T9215 Wendeplatten - Tungaloy

Take advantage of a CVD-coated T9215 grade that combines high wear resistance with fracture toughness and a 0.8 mm nose radius in an ISO rhombic format for reliable medium-steel turning. The combination of sturdy cemented carbide and an 80° geometry ensures productive, continuous or lightly interrupted cuts; order directly via Metav Werkzeuge or consult the specialists for application advice.

CNMG120408 T9215 rhombic ISO turning insert for Turning — Tungaloy

The CNMG120408 T9215 is an ISO-format rhombic indexable turning insert designed for external and internal turning in medium steels, offering a balance of wear resistance and breakage safety for productive machining.

• CVD-coated carbide T9215
• Optimised for medium steel
• Rhombic 80° geometry, 0° relief
• 0.8 mm nose radius, double-sided chipbreaker

Consistent productivity through CVD-coated wear resistance

The CVD-coated T9215 grade is engineered for medium steel machining and provides a reliable compromise between abrasion resistance and edge stability. The CVD-coated surface reduces flank wear under continuous and slightly interrupted cuts, extending tool life and supporting longer production runs. As an ISO insert, it fits into standard clamping systems; compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness. The result is a predictable process window that supports higher productivity with fewer tool changes.

Geometry tuned for surface finish and dimensional control

The rhombic insert shape with an 80° cutting angle and 0° relief gives stable engagement for both facing and turning operations, while the 0.8 mm nose radius contributes to a consistent surface finish and improved edge strength. The insert thickness of 4.76 mm and the cylindrical hole for mounting ensure secure fixation in compatible holders, reducing vibration and improving repeatability. These geometric choices support tighter tolerances and a measurable improvement in part quality on medium-steel components.

System benefits and selection guidance for efficient integration

As part of the ISO turning insert system, the plate works in conjunction with the matching external holder or boring bar, backing pad and clamping set; replacement screws are standardised. The cemented carbide substrate provides the core toughness, while the double-sided chipbreaker allows economical use by flipping the insert when one side is worn. For best results, select the chipbreaker and grade according to workpiece material, machining method and machine stability—this reduces scrap and increases throughput while keeping process costs transparent.

FAQ

What materials is this insert suited for?
The CNMG120408 T9215 insert is optimised for medium steels; the T9215 grade pairs CVD-coated wear resistance with edge toughness for productive machining of steel components.

Can the insert be used for interrupted cuts?
Yes, the cemented carbide substrate and T9215 coating tolerate continuous to lightly interrupted cuts; heavy interruptions may require a different grade or positive geometry.

How is the insert mounted in a holder?
The plate features a cylindrical hole and standard ISO dimensions; secure mounting depends on matching holder form, clamping set and tolerance class to the CNMG120408 geometry.

Is the chipbreaker reversible?
The indexable plate has a double-sided chipbreaker, allowing the insert to be rotated or flipped to use a fresh cutting edge, improving cost-efficiency.

Which feature most improves productivity?
The combination of CVD-coated T9215 and the robust 0.8 mm nose radius provides extended tool life and reliable surface finish, supporting longer runs with fewer interruptions.
