CCMT120408 T6215 Tungaloy indexable turning insert — CVD-coated carbide, 0.8 mm nose radius

A CCMT120408 T6215 indexable turning insert engineered for turning operations, optimised for rostfreiem Stahl (stainless steel) under stable to lightly interrupted cutting conditions.

• CCMT120408 rhombic 80° geometry
• CVD-coated carbide grade T6215
• 0.8 mm nose radius for balanced finish
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for stainless-steel turning

The CVD-coated carbide matrix of this insert delivers improved wear resistance and thermal stability, which supports longer tool life when machining stainless steel under consistent conditions. The hardened coating reduces flank wear and preserves the cutting edge, so surface quality remains predictable over extended cycles. This results in fewer tool changes and steadier process output, benefitting productivity in high-mix or batch production where reproducibility is critical.

Secure mounting and geometry that match standard toolholders

Compatibility with a toolholder is governed by form, relief angle, tolerance class, mounting and thickness; the rhombic 80° profile and 7° relief angle ensure the insert seats correctly in ISO-style external holders and boring bars. The 4.76 mm plate thickness and the central hole with a cylindrical bore plus a one-sided countersink (40°–60°) give reliable clamping and repeatable location. As a consequence, set-up times are reduced and runout or misalignment risks are minimised, supporting consistent cutting forces and improved dimensional control.

Controlled chip formation and dependable surface finish

With a single-sided chipbreaker and a 0.8 mm corner radius, the geometry balances edge strength and the ability to produce a good surface finish on rostfreiem Stahl. The tool system is typically composed of an ISO insert, a matched external holder or boring bar, a shim/clamping set and spare screws; correct matching of chipbreaker and grade to workpiece material and process stability improves chip evacuation and lowers the probability of built-up edge. As a result, machining efficiency is elevated while maintaining repeatable surface quality and component tolerances.

FAQ

Which materials is this insert best suited for?
The CCMT120408 T6215 Tungaloy insert is optimised for stainless steel machining and provides wear resistance suitable for stable to slightly interrupted turning operations.

What is the corner radius and how does it influence finish?
The insert has a 0.8 mm corner radius; this radius offers a compromise between cutting-edge strength and the ability to achieve a fine surface finish when feeds and speeds are selected appropriately for the CCMT120408 T6215 geometry.

How is the insert clamped and what hole does it require?
Clamping is achieved via the central cylindrical hole with a one-sided countersink (40°–60°); the feature ensures secure seating in ISO-compatible holders for the CCMT120408 T6215 insert.

Can this grade handle interrupted cuts?
The T6215 CVD-coated grade is designed for stable to lightly interrupted cutting; for heavy interruptions, a different grade or more robust geometry should be considered to protect edge life.

What components complete the cutting system for this insert?
A typical system comprises the ISO insert, a matching external holder or boring bar, a shim/clamping set and spare screws to ensure correct seating and repeatability for the CCMT120408 T6215 insert.
