WNMA 080416 T5125 trigon turning insert by Tungaloy — CVD-coated carbide, 80° geometry

The WNMA080416 T5125 is an ISO-standard trigon turning insert intended for external and internal turning, engineered to handle interrupted cuts and less rigid set-ups when machining cast iron.

• Trigon shape, 80° cutting geometry
• CVD-coated carbide grade T5125
• Corner radius 1.6 mm for robust engagement
• Cylindrical hole for secure clamping

Reliable performance for interrupted cuts

The insert’s T5125 grade is a CVD-coated carbide designed to combine toughness with wear resistance, making it particularly suitable for cast iron under interrupted cutting conditions. The CVD coating provides a hard outer layer for abrasion resistance while the substrate retains sufficient toughness to resist chipping. In practice, this means fewer unplanned tool changes and steadier part quality when turning disruptive contours or interrupted surfaces. The ISO nomenclature ensures interchangeability with matched holders, supporting consistent production.

Compatibility and secure clamping reduce downtime

Built to ISO dimensions, the trigon form and the cylindrical hole ensure reliable retention in compatible external holders or boring bars. Compatibility is determined by insert form, clearance angle, tolerance class, fastening and thickness; matching these parameters to the toolholder eliminates fitment issues and reduces vibration. A clearance angle of 0° and the 80° cutting geometry provide predictable engagement characteristics that facilitate secure clamping and repeatable positioning during index changes.

Improved edge life and process stability

The 1.6 mm corner radius offers a compromise between edge strength and profile fidelity: it increases resistance to edge chipping during coarse or interrupted cuts while still permitting acceptable surface finish. Stable chip formation is supported by the grade’s balance of toughness and hardness, which helps maintain cutting-edge integrity over longer tool life. The result is a tangible uplift in process stability and reduced frequency of regrinds or replacements, which benefits throughput and production planning.

Practical workshop handling and system setup

The insert functions within a system comprising an ISO trigon insert, a matched external holder or boring bar, a shim/seat and the appropriate clamping screw set. As this variant is supplied without a chipbreaker, selection of feeds, speeds and holder rigidity should be aligned with the workpiece material and machining strategy. For straightforward operations on cast iron and similar materials, the combination of the trigon form, T5125 grade and secure clamping offers a practical balance between productivity and reliability.

FAQ

What materials is this insert suited for?
The T5125 grade is formulated for cast iron machining and performs well in interrupted cuts; it is supplied as a CVD-coated carbide insert for turning applications.

How is the insert secured in a holder?
The trigon insert uses a cylindrical hole and ISO clamping geometry; secure mounting requires a compatible holder that matches form, size and fastening specifications.

Does the insert include a chipbreaker?
This variant is supplied without a chipbreaker, so feed and speed selection should be adapted to the workpiece and the holder rigidity to ensure effective chip control.

What advantage does the 1.6 mm corner radius offer?
A 1.6 mm radius increases edge strength and reduces the risk of chipping in interrupted cuts, improving process stability and extending edge life.

Is this an ISO-standard product for easy replacement?
Yes — the insert is manufactured to ISO dimensions (080416), enabling straightforward replacement and compatibility with standard ISO trigon holders.
