CNMG 090408 T6215 indexable insert for Turning — Tungaloy

CNMG090408 T6215 is an ISO-standard indexable turning insert engineered for stable to lightly interrupted turning of stainless steel, combining a wear-resistant CVD coating with proven geometry for reliable machining.

• CVD-coated carbide T6215 for stainless steel
• ISO CNMG090408 rhombic insert, 80° lead angle
• Double-sided chipbreaker with cylindrical hole

Longer tool life through a robust CVD coating

The CVD-coated T6215 grade provides a balance of wear resistance and edge stability that is particularly suited to machining stainless steel under consistent cutting conditions. Chemical vapour deposition builds a hard, adherent coating layer that reduces flank wear and helps to maintain the cutting edge at higher temperatures than an uncoated substrate. For production environments where tool-change frequency affects cycle time, the coated carbide substrate translates into measurable process stability and lower tooling costs over time.

Precise geometry that simplifies clamping and setup

Built to ISO dimensions, the rhombic insert features a 80° approach angle, 0° clearance and a 0.8 mm corner radius, enabling predictable cutting behaviour and surface finish. The CNMG090408 format is compatible with standard ISO external holders and boring bars; compatibility depends on holder form, clearance angle, tolerance class, fastening and plate thickness. The insert’s cylindrical hole and double-sided design allow economical use of both cutting edges while keeping spare part inventories compact. Reduced setup complexity leads to faster changeovers and less downtime on the shop floor.

Controlled chip formation for consistent finishes

The double-sided chipbreaker geometry supports chip control in both external and internal turning operations, helping to avoid stringing and improving surface quality. Effective chip management reduces rework and protects the tool edge and workpiece, especially when machining longer parts or interrupted sections. For processes where surface integrity is critical, the combination of grade and chipbreaker delivers a reproducible finish with fewer corrective passes.

Practical application and system considerations

This insert is intended for turning operations on stainless steel under stable to mildly interrupted conditions; matching the chipbreaker and grade to the specific alloy and rigidity of the setup is essential for optimal results. The working system comprises the ISO indexable insert, a compatible external holder or boring bar, appropriate shim or clamp and replacement screws. Workshop and production engineers will value the insert’s predictable performance in serial production and job-shop environments where material variety and repeatability are priorities.
