WNMG 080408 KS20 — Indexable turning insert, 80° geometry (Tungaloy)

The WNMG 080408 KS20 is an ISO‑format indexable insert for turning, designed for external and internal turning tasks and interchangeable with compatible holders.

• ISO‑standard trigon insert for turning
• KS20 Tungaloy grade for wear resistance
• 0.8 mm nose radius for precise profiles
• Cylindrical hole, 0° clearance, 4.76 mm thickness

Reliable cutting performance through material and grade

The WNMG080408‑SA KS20 insert combines a tungsten carbide substrate with Tungaloy's KS20 grade to balance wear resistance and edge stability. This grade is formulated to maintain cutting edge integrity under interrupted cuts and continuous turning operations, which reduces the frequency of tool changes and supports steady cycle times. The result is improved process reliability and repeatable surface quality, especially where controlled flank wear is preferable to rapid edge failure.

Predictable fit for fast set‑up and repeatability

Adherence to the ISO‑standard geometry and the trigon form ensures the insert seats reliably in matching external holders and boring bars. Compatibility is determined by form, clearance, tolerance class, fixing method, size and thickness; the trigon shape with a cylindrical hole and 0° clearance angle simplifies alignment and clamping. The 4.76 mm plate thickness and standard dimensions enable predictable clamping forces and repeatable concentricity, reducing set‑up time and the need for adjustment between jobs.

Efficient turning and improved surface finish

With the chipbreaker SA geometry and a 0.8 mm nose radius, this insert supports controlled chip formation and stable contact at the tool tip, which contributes to consistent surface finish and dimensional accuracy in both external and internal turning. The insert is intended for integration into a system comprising a matching external holder or boring bar, a shim/clamping set and replacement screws; selecting the appropriate chipbreaker and grade according to workpiece material and machining stability optimises productivity and tool life.

FAQ

What materials is this insert suitable for?
The WNMG080408‑SA KS20 is a tungsten carbide insert and the KS20 grade is designed to provide a balance of wear resistance and toughness; it is suitable where a robust, general‑purpose grade is required for turning operations.

How does the 0.8 mm nose radius affect surface finish?
A 0.8 mm nose radius on the insert promotes a smoother surface finish and better profile control compared with a smaller radius, while maintaining acceptable cutting forces for many turning applications.

Is the insert compatible with standard WNMG holders?
Yes, the ISO‑standard WNMG geometry and trigon form are made to fit matching WNMG external holders and boring bars, provided the holder accepts the corresponding size, thickness and clamping style.

What is the purpose of the chipbreaker SA?
The chipbreaker SA is engineered to control chip flow and support stable cutting conditions, which helps to prevent entanglement and improves surface integrity during turning.

Which system parts are required to mount the insert?
A complete assembly typically includes a matching external holder or boring bar, a shim or clamping set and the appropriate replacement screws to secure the insert.
