CNMG 090404 T6215 indexable turning insert for turning (Tungaloy)

The CNMG090404 T6215 is an ISO‑standard indexable insert designed for external and internal turning, optimised for stainless steel under stable to lightly interrupted cutting conditions.

• CVD-coated wear-resistant grade T6215
• Optimised for stainless steel turning
• Rhombic CNMG form with 0.4 mm radius
• Double-sided insert with cylindrical hole

Consistent wear performance for turning stainless steels

The CVD‑coated T6215 grade combines a wear‑resistant coating with a robust carbide substrate to extend tool life when machining stainless steel. This results in more predictable tool change intervals and reduced downtime, supporting higher overall productivity. Because the grade is developed for stable to lightly interrupted cuts, users benefit from a balance between edge stability and resistance to flank wear, which helps to maintain dimensional accuracy and surface finish over longer component runs.

ISO compatibility and safe clamping for process reliability

As an ISO‑standard plate in CNMG geometry, the insert ensures straightforward integration into established clamping systems. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; this insert features a rhombic shape, a cylindrical central hole and a 0° clearance angle, making it suitable for many ISO CNMG holders. Correct seating on the underlay/shim and torque to the manufacturer's specification promote repeatable cutting performance and reduced vibration, thereby improving surface quality and tool life.

Practical application notes to increase machining efficiency

Intended for both external and internal turning, the insert’s double‑sided design provides economical use of cutting edges and simplifies inventory management. Match the chipbreaker to the component material and machining stability for optimal chip control; the double‑sided chipbreaker supports flexible orientation depending on feed and depth of cut. Integration into a system comprising the insert, a suitable external holder or boring bar, a backing shim and correct screws reduces set‑up time and aids consistent results across batch production.

Material suitability and process recommendations

This grade is particularly suited to machining stainless steel where wear resistance and a stable cutting edge are priorities. For materials prone to work‑hardening, maintain stable cutting parameters and consider modest feeds to avoid excessive temperatures at the cutting edge. Use of appropriate coolant or lubricant, if compatible with the workpiece, will aid chip evacuation and thermal control. The indexable geometry supports reliable finishing and medium cutting operations when paired with the correct holder and process settings.
