CNMG090402 T6215 CNMG 090402 Turning Insert by Tungaloy — CVD-coated carbide for stainless steel turning

A CNMG090402 T6215 indexable turning insert designed for ISO-compatible holders, providing wear-resistant performance in stable to lightly interrupted turning of stainless steel.

• CVD-coated carbide grade T6215
• ISO CNMG090402 rhombic insert
• Double-sided chipbreaker for stability
• Cylindrical central hole for secure clamping

High-performance grade for stainless steel turning

The insert uses a CVD-coated carbide substrate, T6215, developed for prolonged tool life when machining stainless steel. The coating improves wear resistance at the cutting edge, reducing flank wear and preserving geometry under continuous operation. For production environments this translates into fewer tool changes and more predictable component quality. The wear behaviour of the grade is suited to stable to slightly interrupted cuts, so the benefit is lower process downtime and improved machining economy.

Precise geometry and secure clamping for repeatable results

Configured as an ISO CNMG rhombic insert with an 80° included angle and 0° clearance, the geometry supports robust cutting engagements while maintaining form accuracy. The cylindrical central hole and standard tolerance classes ensure consistent seating in compatible holders, while the 4.76 mm plate thickness and 0.2 mm corner radius enable reliable strength and defined corner transitions. These characteristics reduce vibration and help achieve repeatable dimensional control when paired with a correctly matched holder.

Improved chip control and machining stability

The double-sided chipbreaker offers chip control adapted to turning operations, guiding swarf away from the cutting zone and reducing the risk of re-cutting. Stable chip formation contributes to better surface finish and predictable cycle times, especially when machining long or contoured stainless parts. The insert’s combination of geometry and chipbreaker design supports higher process reliability, which is particularly valuable in batch production and when consistent surface integrity is required.

Practical guidance for selection and integration

The insert is part of an ISO-indexable system: select a suitable external holder or boring bar that matches the insert form, clearance angle, thickness and fastening method. When integrating into a toolset, consider the workpiece material, depth of cut and stability of the setup to choose the most effective chipbreaker and cutting parameters. If uncertain about holder compatibility or optimal cutting data, the technical team at Metav Werkzeuge can advise on clamping options and parameter tuning to maximise tool life and component quality.

FAQ

What materials is this insert intended for?
The CNMG090402 T6215 insert is designed primarily for machining stainless steel and performs best in stable to lightly interrupted turning conditions.

How does the insert secure to the holder?
The insert features a cylindrical central hole and ISO-standard form that allow secure clamping in compatible external holders or boring bars when assembled with the correct clamping set and screw.

Can this insert be used for interrupted cuts?
Yes, the T6215 grade is formulated for stable to lightly interrupted machining; heavier interruptions may require a different geometry or grade for optimal performance.

What benefits does the CVD coating provide?
The CVD coating on this carbide grade improves wear resistance and edge life, leading to longer tool life and more consistent surface quality during production turning.

Is the chip control suitable for long-turning operations?
The double-sided chipbreaker supports improved chip guidance and is beneficial for many turning tasks, helping to maintain surface finish and reduce the risk of re-cutting chips.
