CNMG090408 T6215 CNMG ISO-090408 turning insert, 80° rhombic — Tungaloy

CNMG090408 T6215 is an ISO-format rhombic indexable insert engineered for external and internal turning of stainless steel under stable to lightly interrupted conditions

• CVD-coated carbide grade T6215
• 80° rhombic geometry for robust turning
• 0.8 mm corner radius for fine finishing
• Double-sided chipbreaker, reversible use
• Cylindrical hole for secure clamping

Reliable wear resistance for stainless steel turning

The CVD-coated carbide material combined with the T6215 grade provides enhanced abrasion resistance and thermal stability, making the insert especially suitable for machining stainless steel in continuous and lightly interrupted operations. The 80° rhombic geometry distributes cutting forces across a stable cutting edge, reducing vibration and enabling consistent surface quality. This wear behaviour leads to fewer indexings and longer productive cycles, which helps to lower overall machining costs while maintaining repeatable results.

Seamless integration with ISO holders and predictable mounting

Compatibility is governed by form, clearance angle, tolerance class, fastening, size and thickness; the CNMG format follows the ISO standard and therefore integrates easily with common external holders and boring bars. The insert’s 4.76 mm thickness and the cylindrical hole ensure secure clamping and correct seating; the 0° clearance angle aligns with typical CNMG holder designs. Reversible, double-sided geometry allows rapid indexing, reducing downtime and simplifying tool inventory management in mixed-production environments.

Stable chip control and sustained productivity

A double-sided chipbreaker tailored to this geometry promotes controlled chip formation for a range of feeds and depths of cut, improving evacuation and minimising re-cut chips on the workpiece. The modest 0.8 mm corner radius supports fine finishing while still offering edge strength for heavier passes when required. Together, these characteristics contribute to higher productivity and process reliability: improved cycle times, reduced tool changes and more consistent part quality, even when machining demanding grades of stainless steel.

FAQ

What materials is this insert suitable for?
The CNMG090408 T6215 insert from Tungaloy is designed primarily for machining stainless steel under stable to lightly interrupted cutting conditions; the CVD coating and carbide base offer good wear resistance on such alloys.

How is the insert secured in the holder?
Clamping is achieved via the centred cylindrical hole and the ISO CNMG pocket in compatible holders; correct seating depends on matching holder form, tolerance class and fastening method.

Can the insert be indexed to use the other cutting edge?
Yes, the insert is double-sided and reversible; indexing provides a rapid edge change and extends usable life before disposal.

What surface finish can be expected with a 0.8 mm corner radius?
A 0.8 mm corner radius balances edge strength and finishing capability; it supports fine surface finishes at modest feeds while still tolerating medium cuts when required.

Is this insert compatible with standard ISO CNMG holders?
The insert follows ISO dimensions for the CNMG090408 format, so it is compatible with standard holders provided the holder’s form, clearance angle and tolerance class match the insert specifications.
