CNMG 120408 T6215 CNMG turning insert — Tungaloy (CVD‑coated carbide, 0.8 mm radius)

CNMG120408 T6215 is an ISO‑standard rhombic turning insert designed for external and internal turning of rostfreien Stahl under stable to lightly interrupted conditions.

• CVD‑coated carbide grade T6215
• ISO‑standard CNMG120408 form
• Suitable for rostfreien Stahl turning
• Double‑sided chipbreaker, cylindrical hole

Reliable tool life and stable cutting performance

The CVD‑coated carbide grade T6215 offers a balanced combination of wear resistance and edge stability, engineered for turning applications on rostfreien Stahl. The coating reduces flank and crater wear under continuous cutting and moderate interruptions, which extends the interval between indexings. For production environments seeking predictable component quality, the grade T6215 provides a measurable improvement in tool life compared with untreated grades while maintaining a stable cutting edge for repeatable results.

Exact geometry for consistent fits and surface quality

With the ISO CNMG120408 geometry and rhombic shape, the insert ensures consistent seating and repeatable orientation in compatible holders. The 0.8 mm corner radius supports a good compromise between edge strength and surface finish, while the 0° clearance geometry is suited to conventional turning set‑ups. Specifying ISO‑compliant plates simplifies inventory and reduces setup variance: holders matched by form, tolerance class, size and thickness will produce reliable results and consistent component surfaces.

Efficient chip control for reduced rework

The double‑sided chipbreaker on this insert promotes controlled chip formation when machining rostfreien Stahl, limiting built‑up edge and improving surface consistency. The central cylindrical hole secures stable clamping and facilitates rapid index changes in modular tool systems. By producing predictable chips and lowering the risk of entanglement, the insert cuts downtime and helps maintain throughput in serial turning operations.

Practical system benefits and application guidance

As part of an ISO‑based system — insert, suitable external holder or boring bar, support shim and spare screws — the plate integrates easily into existing toolsets. The CVD coating and carbide substrate suit stable to lightly interrupted cutting; selecting the appropriate chipbreaker and grade for the workpiece material and operational stability is recommended. For alternating or heavily interrupted cuts, consider system adjustments or a different geometry to protect tool life and part quality.

FAQ

What materials is this insert suitable for? The CNMG120408 T6215 insert is specified for machining rostfreien Stahl under stable to lightly interrupted conditions and is supplied as a CVD‑coated carbide plate for improved wear resistance.

How does the chipbreaker affect machining? The double‑sided chipbreaker promotes consistent chip formation and reduces built‑up edge when cutting rostfreien Stahl, which helps to secure surface quality and reduce secondary operations.

Is this an ISO‑standard geometry and will it fit existing holders? Yes, the plate uses the ISO CNMG120408 form; compatibility depends on holder form, free‑angle, tolerance class, fastening, size and thickness, so holders conforming to the same ISO parameters will accept the insert.

What are the key dimensional specifications to check before ordering? Important dimensions include the 12 mm size, 4.76 mm thickness, 0.8 mm corner radius and the 80° included angle; the plate also features a cylindrical hole for secure clamping.

Which applications should avoid this insert? This grade and geometry are optimised for stable to lightly interrupted turning of rostfreien Stahl; heavily interrupted cuts or highly abrasive materials may require a different grade or protective measures.
