CNMG 120408 T6215 – CNMG ISO turning insert for turning by Tungaloy, CVD‑coated carbide, 0.8 mm radius

CNMG120408 T6215 indexable turning insert for external and internal turning, designed for stable to lightly interrupted conditions and optimised for rostfreier Stahl machining

• CVD‑coated carbide for high wear resistance
• ISO‑standard CNMG 120408 compatibility
• 0.8 mm nose radius for fine turning
• Double‑sided chipbreaker, with cylindrical hole

Predictable wear behaviour for extended production runs

The CVD‑coated grade T6215 delivers consistent abrasion resistance under the moderate thermal and mechanical loads typical of rostfreier Stahl turning. The CVD‑coated carbide surface slows flank and crater wear, which extends edge life and reduces unscheduled tool changes. This leads to a higher yield per cutting edge and more predictable maintenance cycles, helping production planners minimise downtime and maintain stable throughput.

Geometry tuned for accuracy and surface finish

The rhombic CNMG form with an included angle of 80° and a 0.8 mm nose radius gives a balance between robustness and fine surface quality. The ISO‑standard geometry ensures interchangeability with standard holders and repeatable results across different machines. A 0° relief angle combined with the rhombic plate form supports controlled cutting forces and consistent dimensional accuracy on both external and internal turning operations.

Economical system integration and secure clamping

This reversible insert features a double‑sided chipbreaker and a cylindrical hole for positive clamping, enabling two usable cutting edges per side and straightforward mechanical fixation. The insert thickness of 4.76 mm and standard size 12 mm simplify stocking and replacement. Compatibility with standard external holders and boring bars is determined by form, relief angle, tolerance class, attachment, size and thickness, allowing quick integration into existing tool systems and reducing setup complexity.

Application guidance and process reliability

Designed specifically for turning, the insert is recommended for rostfreier Stahl under stable to slightly interrupted conditions; choosing the appropriate chipbreaker and machining parameters will determine finish and tool life. Where light interruptions or unstable clamping occur, select a more robust chip control strategy and adjust feeds accordingly. Backed by Tungaloy’s manufacturing standards, the insert supports consistent process results and repeatable part quality, making it suitable for batch and series production where reliability matters.

FAQ

What materials is this insert suitable for?
The CNMG120408 T6215 insert is intended primarily for machining rostfreier Stahl and performs best under stable to lightly interrupted turning conditions.

How many usable edges does the insert provide?
Thanks to the double‑sided chipbreaker and reversible design, the insert offers multiple usable cutting edges, improving cost efficiency for series production.

Is this insert compatible with standard CNMG holders?
Yes, the ISO‑standard CNMG 120408 geometry ensures compatibility with holders and boring bars that accept CNMG inserts of the same size and tolerance class.

What does the T6215 grade provide compared with general grades?
The T6215 grade features a CVD‑coated carbide formulation optimised for wear resistance when machining rostfreier Stahl, offering longer edge life under the specified conditions.

What are the key dimensions to verify before ordering?
Check the insert size (12 mm), thickness (4.76 mm), nose radius (0.8 mm) and relief angle (0°) to ensure fit with existing toolholders and the required machining geometry.
