CNMG 120412 T6215 Turning Insert – ISO CNMG, CVD-coated Carbide – Tungaloy

The CNMG120412 T6215 Tungaloy insert is an ISO-standard turning insert designed for external and internal turning, optimised for machining stainless steels under stable to slightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Designed for stainless steel turning
• ISO CNMG geometry with 80° lead angle
• Double-sided chipbreaker and cylindrical hole

Proven wear resistance for stainless-steel machining

The CVD-coated carbide composition of this insert delivers high wear resistance and stable edge life when machining stainless steel. A chemical vapour deposition layer enhances resistance to abrasive and adhesive wear mechanisms commonly encountered with high-alloy materials, which translates into fewer tool changes and more predictable cycle times. For production environments where surface finish and repeatability matter, the coating supports prolonged performance under steady cutting conditions and when light interruptions occur.

Secure clamping and geometry that supports precision

With an ISO CNMG form, an 80° lead angle and a 1.2 mm corner radius, the insert is engineered for dimensional stability and versatile edge engagement. The 4.76 mm thickness and rhombic profile contribute to stiffness in the clamping assembly, while the cylindrical hole enables positive centring and fastening in standard indexable holders. These geometric attributes help to reduce chatter and improve surface quality, allowing the tool system to maintain tighter tolerances on turned components across batches.

Efficient chip control and system-oriented productivity

The double-sided chipbreaker promotes controlled chip formation and evacuation, which reduces re-cutting and supports steady cutting forces. Being an indexable design, the insert can be rotated to present a fresh cutting edge, maximising useful life per insert. The insert forms part of a complete system: ISO-compatible turning holder or boring bar, support shim or clamp set and replacement screws ensure safe fixation and repeatable set-up. Together, these features contribute to higher uptime and a more efficient machining process in component manufacturing.

FAQ

Which materials is this insert best suited for?
The CNMG120412 T6215 Tungaloy insert is engineered primarily for stainless steel machining; the CVD-coated carbide grade offers wear resistance suited to alloyed, high-chromium materials.

What are the key geometric specifications of the insert?
This CNMG120412 insert features an 80° lead angle, 1.2 mm corner radius, 4.76 mm thickness and a 12 mm inscribed size, providing a balance of strength and edge engagement for general turning tasks.

Will this insert fit standard ISO CNMG holders?
Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the CNMG120412 follows ISO geometry and is compatible with holders designed for CNMG inserts when those parameters match.

How does the T6215 coating improve performance?
The T6215 CVD coating increases resistance to abrasive wear and edge degradation during turning of high-alloy steels, extending tool life and stabilising cutting conditions.

Does the insert provide effective chip control and indexing?
Yes, the double-sided chipbreaker promotes controlled chip formation, and the indexable design allows the insert to be rotated to a fresh cutting edge for extended service life.
