CNMG120404 T6215 indexable insert for turning – Tungaloy

The CNMG120404 T6215 is an ISO-standard rhombic indexable insert designed for external and internal turning, offering wear-resistant performance on stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• ISO CNMG 120404 rhombic insert
• Double-sided chipbreaker, with hole
• Suitable for turning of stainless steel

Durable wear resistance for confident stainless-steel machining

The insert combines a CVD-coated carbide substrate with the T6215 grade to deliver high wear resistance in demanding stainless-steel turning. The multilayer CVD treatment improves thermal and abrasive durability, which reduces flank wear and extends tool life under continuous cuts. With a 0° clearance angle and a 0.4 mm corner radius, the geometry supports predictable engagement and helps maintain consistent part tolerance when machining rotational components.

Reliable chip control and secure mounting for stable operations

A double-sided chipbreaker and a cylindrical hole for positive clamping ensure controlled chip formation and repeatable seating in ISO-compatible toolholders. The rhombic CNMG shape with an 80° included angle balances cutting strength and accessibility for both external profiles and internal shoulders. Compatibility depends on holder form, relief angle, tolerance class, fixation and thickness, so the ISO standardisation simplifies selection for common turning tool systems.

Increased productivity through predictable performance

Using the CNMG120404 T6215 indexable insert in stable to slightly interrupted cuts reduces unplanned tool changes and supports steady cycle times. The 4.76 mm thickness and robust carbide substrate provide mechanical strength, while the CVD coating helps manage heat at the cutting edge. The net effect is a more economical process: fewer interruptions, consistent surface finish and a reproducible tool life that aids in planning production runs and tooling budgets.

Practical specifications and selection guidance for workshop use

The plate measures an inscribed circle of 12 mm, a thickness of 4.76 mm and features a 0.4 mm corner radius, making it suitable for fine finishing and medium-turning passes on stainless materials. Choose the chipbreaker style and grade to match workpiece stability and feed strategy; double-sided inserts allow economical indexing. The system build typically includes the ISO insert, a compatible external holder or boring bar, backing pads and clamping screws for secure assembly.

FAQ

What materials is this insert best suited for?
The CNMG120404 T6215 insert is engineered for stainless steels, offering wear resistance and heat management suited to a broad range of austenitic and martensitic grades.

Is the insert compatible with standard CNMG toolholders?
Yes, the ISO CNMG geometry and the cylindrical hole are designed for compatibility with standard CNMG external holders and boring bars, subject to matching form, clearance and thickness.

What cutting conditions are recommended for this grade?
The T6215 grade performs best under stable to lightly interrupted turning conditions where its CVD coating and carbide core deliver consistent life and surface finish.

Can the insert be indexed to use both sides?
Yes, the insert is double-sided; both faces have the same geometry and chipbreaker, allowing economical indexing and extended tool utilisation.

Which dimensions are critical when selecting a matching holder?
Key dimensions include the inscribed circle (12 mm), thickness (4.76 mm), corner radius (0.4 mm) and the 0° clearance angle—all must match the holder’s seat and clamp design for secure mounting.
