CNMG120404 T6215 — Turning insert (CVD-coated carbide, 0.4 mm radius) by Tungaloy

The CNMG120404 T6215 is an ISO-format, rhombic turning insert designed for stable to lightly interrupted machining of stainless steels, offering a balanced combination of wear resistance and consistent surface finish.

• CVD-coated carbide for wear resistance
• ISO CNMG 120404 rhombic insert
• 0.4 mm corner radius for precision
• Cylindrical hole for secure clamping

Longer tool life when machining stainless steels

The CVD-coated carbide grade is formulated to resist abrasive and adhesive wear typical of stainless steels, extending tool life compared with uncoated grades. The coating reduces flank wear and preserves the cutting edge under stable to lightly interrupted conditions, so production runs require fewer insert changes and deliver consistent part quality. This directly translates into reduced machine downtime and a lower cost per component without compromising surface finish.

Secure mounting and fast indexable changes for uptime

With its ISO CNMG format, rhombic geometry and a cylindrical hole, the insert ensures reliable seating and repeatable positioning in standard external holders or boring bars. The 4.76 mm thickness and 80° geometry provide mechanical stability during turning operations, enabling secure clamping and predictable cutting behaviour. As a result, downstream processes benefit from repeatable concentricity and fewer rework cycles, supporting leaner production flows.

Controlled chips and consistent surface quality

The double-sided chipbreaker and the 0.4 mm corner radius are matched to the grade to promote stable chip formation and improved surface integrity in turning. Controlled chip flow reduces the risk of workpiece damage and tool interference, while the modest corner radius balances edge strength with the ability to achieve fine finishes. When surface quality and process reliability matter, this indexable insert supports efficient machining strategies on a wide range of stainless steel components.

FAQ

What material is the insert designed for? The CNMG120404 T6215 insert is optimised for machining stainless steels, using a CVD-coated carbide grade to resist the specific wear mechanisms of these alloys.

Is the insert compatible with standard CNMG holders? Yes, the insert follows the ISO CNMG 120404 format and fits holders that accept CNMG plates; compatibility depends on holder form, size and clamping system.

How does the 0.4 mm corner radius affect the finish? A 0.4 mm corner radius provides a compromise between edge strength and surface finish, enabling improved edge life while still achieving fine surface quality on turned parts.

Can the insert be used for interrupted cuts? The grade and geometry are intended for stable to lightly interrupted cutting; heavier interruptions may require a different geometry or a more robust grade.

Is the chip control suitable for automated turning cells? Yes, the double-sided chipbreaker and consistent chip formation make the insert well suited to automated turning operations where predictable chip flow is essential.
