CNMG120404 AH6225 CNMG turning insert for turning – PVD-coated carbide, 0.4 mm radius | Tungaloy

A CNMG120404 AH6225 insert designed for ISO-standard turning applications, offering a balanced combination of edge sharpness and robustness for machining stainless steels

• PVD-coated carbide grade AH6225
• Universal for stainless steels and turning
• Rhombic ISO shape, 80° included angle
• Double-sided chipbreaker, cylindrical hole

Consistent cutting performance for stainless steels

The insert delivers a reliable balance between edge sharpness and stability thanks to the PVD-coated carbide matrix of grade AH6225, which is formulated for turning stainless steels under changing production conditions. This composition helps maintain a stable cutting edge during medium machining, reducing the frequency of tool changes and supporting consistent surface quality. The controlled coating improves wear resistance and adhesion, which in turn contributes to more predictable tool life and fewer unexpected stoppages on the shop floor.

Engineered geometry for secure clamping and accurate fitting

Manufactured to ISO dimensions, the rhombic plate with an 80° included angle and a 0° clearance angle is compatible with holders when form, tolerance class, attachment method, size and thickness match. The insert’s 0.4 mm corner radius and cylindrical hole suit common clamping systems and ensure repeatable seating. Specifying the correct holder and shim set is essential: compatibility is determined by the insert form and the holder’s seating geometry, so choosing matched components preserves cutting accuracy and reduces setup time.

Efficient chip control and versatile application range

The double-sided chipbreaker supports reliable chip formation across varying cutting conditions and helps prevent entangling or inconsistent chip shapes that can affect finish quality. The grade and chipbreaker combination makes the insert well suited for both external and internal turning tasks where medium cutting parameters are required. Selecting the appropriate chipbreaker and adapting feeds or depths according to workpiece stability will optimise process reliability and throughput, delivering cost-effective productivity gains.

Practical system considerations and handling advice

The standard system comprises the ISO insert, a matched external holder or boring bar, a shim/clamp set and replacement screws; correct assembly and torqueing of the clamp set are decisive for repeatable results. The insert thickness of 4.76 mm and the size designation 12 align with common ISO holders; the plate’s rhombic form supports a range of turning contours. For batches with variable setups, keeping a stock of shims and spare fasteners reduces downtime. For tailored cutting parameters or holder recommendations, technical consultation is available to optimise performance for the specific material and machining stability.

FAQ

Which materials is this insert suitable for? The CNMG120404 AH6225 insert from Tungaloy is formulated primarily for stainless steels, offering a good balance of sharpness and edge stability for medium turning operations.

How does the AH6225 PVD coating benefit machining? The PVD-coated AH6225 grade on the CNMG120404 improves wear resistance and provides more consistent edge behaviour, which helps maintain surface finish and extend effective tool life under varying conditions.

What determines holder compatibility for this ISO insert? Compatibility is governed by the insert form, clearance angle, tolerance class, attachment method, size and thickness; the CNMG120404 must be paired with an ISO-compatible holder and appropriate shim/clamp set to ensure correct seating and clamping.

Is the chipbreaker suitable for internal turning operations? Yes, the double-sided chipbreaker on this plate supports reliable chip control for both external and internal turning when the correct feed and depth settings are used and workpiece support is adequate.
