CNMG 120402 T9215 — ISO turning insert (rhombic, 80°) by Tungaloy

The CNMG120402 T9215 is an ISO rhombic indexable insert for external and internal turning, engineered for productive machining of medium-strength components with a stable chipformer and reliable wear resistance

• CVD-coated carbide T9215 for high wear resistance
• Rhombic 80° geometry for stable cutting forces
• 0.2 mm corner radius for accurate contouring
• Double-sided chipbreaker for economical indexing

Higher productivity through targeted coating and substrate

The combination of a CVD-coated surface and a cemented carbide substrate provides a controlled wear pattern and consistent edge life, which directly reduces machining interruptions. This grade is tailored for medium-duty applications where a balance between wear resistance and fracture toughness is required; the result is longer intervals between indexings and fewer unscheduled tool changes. The engineered coating chemistry ensures predictable performance under continuous to slightly interrupted cuts while maintaining surface integrity on the workpiece.

Geometry that stabilises the cut and improves surface finish

An 80° included angle in a rhombic format delivers a wide bearing surface that dampens vibrations and distributes cutting loads. The modest 0.2 mm corner radius allows precise profile work without sacrificing edge strength, making the insert suitable for finishing passes and light roughing when stability is maintained. The zero-degree clearance specification supports a neutral cutting action that helps achieve consistent dimensional results and an improved nominal surface quality.

Practical compatibility and reliable clamping

As an ISO-standard insert, this indexable plate integrates into common holder systems when form, clearance angle, tolerance class, fastening and size match. The insert is furnished with a cylindrical hole, enabling secure mounting and repeatable positioning in compatible toolholders or boring bars. The double-sided chipbreaker design extends usable life by offering two cutting edges per index, increasing economy in high-volume setups without complex regrinding procedures.

Choosing the right chipformer and process parameters

Selecting the appropriate chipbreaker and cutting data maximises the benefits of the T9215 grade: for continuous cuts prefer moderate feed rates with stable support; for slightly interrupted conditions reduce cutting speed and favour the robust substrate to avoid chipping. The insert suits both external and internal turning operations when paired with a matching holder and correct clamping torque. Process planning that prioritises rigidity and consistent coolant supply will leverage the insert’s strengths for reproducible production output.

FAQ

What materials is this insert intended for?
The CNMG120402 T9215 insert from Tungaloy is optimised for medium-strength metals and components where a balance of wear resistance and toughness is required; it performs well on typical medium alloy and carbon workpieces.

How many usable edges does the insert provide?
This indexable plate features a double-sided chipbreaker, offering two primary cutting edges per side and therefore multiple indexing positions to extend effective tool life.

Is the insert compatible with standard CNMG holders?
Compatibility depends on matching form, clearance angle, tolerance class, fastening and size; the CNMG120402 conforms to ISO dimensions, so it fits holders specified for CNMG 120402 inserts when those parameters align.

Which cutting situations suit the T9215 grade best?
T9215 is designed for productive machining under continuous to slightly interrupted cuts where consistent wear resistance is required without compromising fracture toughness.

What benefits does the CVD coating provide on this insert?
The CVD-coated surface on the CNMG120402 T9215 improves wear resistance and stabilises edge behaviour, supporting longer service intervals and more reproducible surface finishes.
