CNMG 120408 T6215 Turning Insert for Turning – Tungaloy

The CNMG120408 T6215 is an ISO-standard indexable turning insert engineered for stable external and internal turning of stainless steel under stable to slightly interrupted cutting conditions.

• CVD-coated carbide for high wear resistance
• Optimised chip former for stainless steel machining
• ISO CNMG120408 – rhombic 80° geometry

Longer tool life through a wear-resistant CVD grade

The CVD-coated carbide grade T6215 combines a hard, wear-resistant coating with a tough substrate to provide extended tool life when machining stainless steel. This coating technology reduces flank wear at elevated temperatures and improves resistance to built-up edge formation, which is especially beneficial during continuous turning operations. Choosing this grade supports longer tool cycles and fewer index changes, delivering measurable gains in production efficiency and lower tooling-related downtime.

Consistent chip control for reliable surface finish

The insert’s double-sided chipformer and rhombic 80° geometry deliver controlled chip breakage and stable contact conditions. A predictable chip flow reduces vibration and improves surface integrity on the workpiece, so machinists obtain consistent finish quality across batches. The 0.8 mm corner radius balances edge strength and cutting forces, offering a compromise between robust performance and acceptable surface roughness in common turning scenarios.

Seamless integration into standard ISO tool systems

Designed as an ISO CNMG insert, compatibility with holders is determined by form, clearance, tolerance class, fastening and size. The insert features a cylindrical hole, a plate thickness of 4.76 mm and a clearance angle of 0°, facilitating secure clamping and straightforward replacement in many external holders and boring bar systems. This predictable fitment reduces set-up time and supports quick tool changes to keep machining cycles short.

Practical guidance for application and process stability

For effective use, match the chipbreaker and grade to the workpiece material and the stability of the set-up: the T6215 grade is optimised for stainless steels under stable to slightly interrupted cutting. Where intermittent cuts or severe interruptions occur, select a more robust edge preparation or adapt cutting parameters to reduce shock loads. When combined with an appropriate holder and correct cutting data, the insert contributes to higher productivity, reliable dimensional accuracy and repeatable performance in series production.

FAQ

What materials is this insert suitable for? The CNMG120408 T6215 insert is designed primarily for machining stainless steel and performs best under stable to slightly interrupted cutting conditions.

How does the T6215 grade affect tool life? Tungaloy’s T6215 CVD-coated carbide reduces wear and built-up edge on stainless steel, resulting in longer intervals between indexing and improved overall tool life.

Is the insert reversible or indexable? Yes, the insert is double-sided with a chipformer on both faces, allowing indexation to present a fresh cutting edge.

Which holders are compatible with this insert? Compatibility depends on holder form, clearance angle, tolerance class, fastening and size; the ISO CNMG120408 form and the cylindrical hole ensure secure fitting in standard CNMG holders.

What corner radius and geometry are specified? The insert features a 0.8 mm corner radius and a rhombic 80° geometry, offering a balance between edge strength and surface finish.
