CNMG120408 T6215 ISO indexable turning insert — Tungaloy

CNMG120408 T6215 is an ISO-format indexable insert designed for turning, optimised for stable to lightly interrupted machining of stainless steel and similar materials

• CNMG120408 geometry, ISO compatible
• CVD-coated carbide grade T6215 for stainless steel
• Double-sided chipbreaker, cylindrical hole

Consistent cutting performance for stainless steel

The CNMG120408 T6215 insert pairs a CVD-coated carbide substrate with a geometry that supports steady cutting in stainless steel. The T6215 grade delivers improved wear resistance, which translates into longer intervals between indexing and lower tooling costs per component. The CVD coating forms a hard outer layer that reduces abrasive wear and helps maintain edge integrity under the thermal and adhesive tendencies common when machining stainless steel, resulting in more consistent part surfaces and fewer unplanned tool changes.

ISO compatibility that reduces setup time and variation

As an ISO-standard insert, the component fits established holders when matched by form, clearance angle, tolerance class, fixation method, size and thickness. This simplifies tool-room inventories and reduces setup time on new jobs. The rhombic plate shape and standardised dimensions mean that replacement and retrofitting into existing toolholders is straightforward, offering reliable repeatability in multi-shift production where process stability and minimal downtime are priorities.

Predictable chip control and extended tool life

The insert’s double-sided chipbreaker geometry and cylindrical hole support secure clamping and repeatable chip formation, which is particularly beneficial when cutting stainless steel where chip control is critical. The modest 0.8 mm corner radius balances edge strength and surface finish, while the 80° approach angle and 0° clearance reduce radial cutting forces in many turning setups. Together, these features produce manageable chips, reduce workpiece marking and contribute to an overall extension of tool life—supporting a lower cost per produced part.

System advice and practical application notes

Indexable-insert systems require the correct combination of insert, holder, shim and screw to achieve the stated performance. The insert is intended for external and internal turning operations under stable to slightly interrupted conditions; choose the chipbreaker and grade to match the workpiece material and machine rigidity. For complex setups or materials with challenging properties, technical consultation is recommended to select suitable cutting parameters and holder geometry so that the full benefits of the T6215 grade and insert form are realised.

FAQ

What materials is this insert best suited for?
The CNMG120408 T6215 insert is optimised for machining stainless steel under stable to lightly interrupted conditions; the CVD-coated carbide formulation improves wear resistance and surface quality for such materials.

How does the T6215 grade affect tool life?
Tungaloy’s T6215 grade provides enhanced wear resistance compared with uncoated carbide, helping to prolong edge life and reduce the frequency of indexing or replacement in production turning operations.

Can this insert be used for internal boring as well as external turning?
Yes; the ISO CNMG geometry and rhombic form enable use in both external and internal turning applications when paired with a suitable holder and correct tool projection.

What is the significance of the double-sided chipbreaker?
The double-sided chipbreaker delivers predictable chip control and allows indexing of the insert to present a fresh cutting edge, improving process stability and reducing tooling cost per part.

Which holder characteristics must be matched for correct fit?
Compatibility depends on form, clearance angle, tolerance class, fixation, size and thickness; ensure the holder matches the CNMG120408 dimensions and the 4.76 mm thickness for correct seating and clamping.
