CNMG120404 T6215 ISO indexable turning insert — CVD-coated carbide for stainless steel turning (Tungaloy)

CNMG120404 T6215 is a robust ISO-indexable turning insert designed for stable to lightly interrupted turning of stainless steels, offering repeatable performance in standard external and internal turning operations.

• CVD-coated carbide grade T6215
• Suitable for turning stainless steel
• Rhombic 80° geometry with 0.4 mm radius
• Cylindrical-hole, double-sided insert

Precise cutting geometry for consistent turning results

The CNMG120404 T6215 indexable insert combines a stable 80° rhombic geometry with a 0.4 mm corner radius to deliver reliable edge engagement and predictable chip formation. The 0° clearance and 4.76 mm plate thickness contribute to secure seating in prescribed ISO holders, which reduces vibration and supports dimensional stability. These measurable geometry parameters make tool-setting and process planning straightforward, allowing engineers to forecast surface finish and tool life more accurately.

Clear guidance on compatibility and holder selection

Compatibility with the chosen toolholder is determined by form, clearance angle, tolerance class, clamping method, size and thickness. The rhombic form and cylindrical hole require a matching ISO external holder or boring bar designed for CNMG-type inserts. Where process stability is high, the double-sided chipbreaker and CVD-coated carbide substrate enable extended cutting intervals; in less stable conditions a suitable grade and chipbreaker must be chosen to suit the workpiece and machining strategy. This guidance simplifies selection and reduces trial-and-error at the machine.

Built for durability and predictable chip control

The T6215 grade combines a wear-resistant CVD coating with a hardmetal substrate to resist adhesion and abrasion common in machining stainless steel. The double-sided chipbreaker supports controlled chip segmentation and evacuation, improving process reliability and reducing downtime for chip clearing. Together, these features help sustain cutting performance over multiple indexings and contribute to a steadier production flow with fewer unexpected tool changes.

FAQ

Which materials is this insert best suited for?
The CNMG120404 T6215 insert and its CVD-coated carbide grade are optimised for machining stainless steel under stable to slightly interrupted cutting conditions.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius balances edge strength and finish quality; the CNMG120404 geometry supports a good surface when combined with appropriate feed and speed settings.

Is the insert reversible or single-edge?
The insert is double-sided with a cylindrical hole; each side offers usable cutting edges allowing for economical indexing.

What does the 80° rhombic geometry mean for holder choice?
An 80° rhombic geometry requires a matching ISO external holder or boring bar designed for CNMG inserts to ensure correct seating and stable cutting action.

Can this insert be used for internal turning as well as external turning?
Yes, the geometry and chipbreaker design make the insert suitable for both external and internal turning applications when used with the correct holder.
