CNMG120404 T6215 turning insert by Tungaloy — ISO CNMG, CVD‑coated carbide for stainless steel

CNMG120404 T6215 is an ISO‑standard rhombic turning insert designed for external and internal turning applications, offering a wear‑resistant CVD coating suited to machining stainless steels under stable to slightly interrupted cutting conditions.

• ISO‑standard CNMG geometry for holder compatibility
• T6215 CVD‑coated carbide for stainless steel turning
• Double-sided chipbreaker with cylindrical hole
• 0° relief angle with 80° approach angle

Precision and material resistance for consistent production

The CNMG120404 T6215 insert combines CVD‑coated carbide with a purpose‑built geometry to deliver consistent tool life when machining stainless steels. The CVD coating enhances abrasion resistance and reduces flank wear, which translates into fewer insert changes and steadier component tolerances. Thanks to the CNMG rhombic form and a modest 0.4 mm corner radius, the insert provides a balance between edge strength and surface finish, making it suitable for both contouring and general turning tasks on medium‑to‑high alloyed workpieces.

Secure clamping and chip control for reliable feeds and speeds

A double‑sided chipbreaker and a cylindrical hole ensure repeatable seating and stable chip formation across reversals of indexable use. The 80° approach angle reduces radial cutting forces and supports dimensional stability during roughing and semi‑finishing passes. Compatibility with ISO holders depends on insert form, relief angle, tolerance class and thickness; matching the holder to the insert geometry preserves cutting edge life and reduces vibration, which in turn improves surface quality and process reliability.

Practical advantages in the workshop and on the shop floor

This indexable insert offers economical use through reversible edges and straightforward indexing, reducing tool inventory and downtime. The T6215 grade is optimised for wear resistance in continuous to lightly interrupted cuts, helping to maintain productivity in serial production. For operations requiring both external and internal turning, the insert’s rhombic shape and standard sizing facilitate straightforward integration into common holder systems, supporting rapid setup and predictable results.
