CNMG120408 T6215 — Tungaloy CNMG turning insert, CVD-coated carbide, 0.8 mm radius
The CNMG120408 T6215 is an ISO-standard indexable turning insert engineered for stable and lightly interrupted turning applications, especially suited to rostfreier Stahl.
- CVD-coated carbide grade T6215
- Optimised for rostfreier Stahl turning
- 0.8 mm corner radius for reliable finishes
- Rhombic CNMG 120408 with cylindrical hole
High wear resistance for dependable rostfreier Stahl turning
The insert's CVD-coated carbide grade T6215 provides a hard, wear-resistant surface that extends tool life in continuous and lightly interrupted cuts. This specification reduces flank wear and preserves edge integrity, delivering more consistent cycle times and fewer insert changes. For production environments where stability is key, the combination of coating and substrate results in improved productivity and lower overall tooling cost per component. The grade's optimisation for rostfreier Stahl means fewer unplanned downtimes caused by premature wear.
Geometry and chip control that stabilise the machining process
A rhombic ISO CNMG form with an 80° approach angle and a 0.8 mm corner radius ensures predictable cutting forces and a balance between edge strength and surface finish. The double-sided chipbreaker design supports controlled chip formation under typical turning conditions, while the cylindrical hole provides secure and repeatable clamping. Compatibility with the toolholder depends on form, clearance angle (0°), tolerance class, fastening, size and thickness; matching these parameters guarantees correct seating and repeatable accuracy for serial production.
Practical system benefits and application guidance
The component forms part of a system consisting of an ISO indexable insert, a matching external holder or boring bar, a shim/clamping set and replacement screws; choosing the right holder and clamping components is essential to exploit the insert's stability and wear resistance. The insert thickness of 4.76 mm and inscribed circle size 12 mm contribute to load distribution at the cutting edge, enabling reliable performance in stable setups. When selecting an insert, pair the T6215 chipbreaker and grade to the workpiece material and machining strategy to achieve the desired surface quality and tool life.

FAQ
Which materials is this insert designed for?
The CNMG120408 T6215 insert from Tungaloy is optimised for machining rostfreier Stahl and performs well under stable to lightly interrupted turning conditions.
What advantages does the T6215 grade provide?
Grade T6215 combines a CVD-coated carbide surface with a wear-resistant substrate to extend edge life, reduce wear rates and maintain consistent surface quality throughout production runs.
How is the insert fixed in the toolholder?
The insert is located via its rhombic geometry and cylindrical hole, and requires a compatible holder, shim/clamping set and replacement screws to ensure secure, repeatable clamping.
Is the insert reversible or indexable?
This is a double-sided indexable insert (CNMG style), allowing it to be rotated or indexed to present a fresh cutting edge, maximising economy and uptime.
What cutting edge geometry influences surface finish?
The 0.8 mm corner radius and the CNMG 80° approach geometry balance edge strength and finish quality; selecting the appropriate radius and feed ensures the required surface specification.
