CNMG120412 T6215 ISO indexable turning insert — Tungaloy

CNMG120412 T6215 is an ISO-standard indexable insert for turning, designed for reliable performance on stainless steels in stable to slightly interrupted cuts

• CVD-coated carbide for high wear resistance
• 80° rhombic geometry with 1.2 mm radius
• Double-sided chipbreaker and cylindrical hole
• ISO CNMG120412 insert for standard toolholders

Consistent wear control for stainless-steel turning

The CVD-coated carbide grade T6215 provides a wear-resistant surface that extends in-process life and supports predictable tool change intervals. Designed for turning stainless steels under stable to slightly interrupted conditions, the insert delivers a balance of thermal and mechanical resistance that reduces flank wear and improves component repeatability. The result is fewer stoppages and a more reliable production flow, translating into measurable gains in machining efficiency.

Secure clamping and geometric strength for versatile turning

The 80° rhombic geometry combined with a 1.2 mm corner radius and 0° relief angle gives structural rigidity for moderate depths of cut while maintaining versatility across external and internal turning applications. With a plate thickness of 4.76 mm and a cylindrical central hole, the insert fits common ISO-compatible holders and bores securely when used with the appropriate shim and clamp set. This mechanical stability supports better surface finish and repeatable tolerance control with standard toolholder systems.

Economy through double-sided use and practical system setup

The double-sided chipbreaker doubles the available cutting edges per index, lowering per-edge cost and simplifying tool logistics. The double-sided chipbreaker also manages chip formation for the intended materials, helping to avoid built-up edge and ensuring consistent surface quality. As an ISO-standard plate, it forms part of a system that comprises the insert, a matched external holder or boring bar, a locating shim/clamp and replacement screws — components to consider when specifying for a given machine and workpiece stability.
