WCGT020102-FN2 WNN10 — Trigon 80° turning and boring indexable insert by Walter Tools, coated carbide, FN2 chipbreaker

WCGT020102-FN2 WNN10 is a hardened, coated indexable insert designed for versatile turning and boring tasks, offering a balance of edge robustness and surface-finish capability for workshop production environments

• Coated carbide grade WNN10
• Trigon 80° geometry for versatility
• FN2 chipbreaker for controlled chips
• 0.2 mm corner radius for fine finish

Consistent process results from a coated carbide grade

The core advantage of this insert is the coated carbide composition of the WNN10 grade, which provides repeatable wear behaviour and extended edge life under a range of cutting conditions. As a coated hardmetal grade, WNN10 combines thermal and mechanical resistance with reliable cutting performance; this results in fewer interruptions for insert changes and more predictable tool costs per component. For production planning, the coated surface also helps reduce built-up edge and supports stable running at moderate to elevated cutting speeds. The specification advises checking the product matrix for detailed workpiece-material recommendations.

Precision geometry that improves surface finish and entry behaviour

The Trigon 80° shape with a 0.2 mm corner radius gives a controlled engagement with the workpiece, helping to reduce vibration and to produce consistent surface quality on external turning and light boring passes. A small corner radius reduces cutting load peaks and is suitable for finishing and semi-finishing operations where a fine profile is required. When mounted in the correct toolholder, the insert geometry supports tight tolerance keeping and repeatable edge contact, which benefits batch production and components requiring reliable dimensional conformity.

Reliable chip control and predictable cutting action

The FN2 chipbreaker has been developed for controlled chip formation on medium-to-thin chip cross-sections; its form assists in breaking and evacuating chips efficiently, reducing the risk of entanglement and re-cutting. Combined with a 7° relief angle, the insert achieves a favourable clearance-to-cut ratio that balances edge strength and cutting efficiency. This combination promotes smooth machining cycles and simplifies tool setting, particularly where consistent chip flow and minimal manual clearing are priorities.

Selection and integration for workshop efficiency

Tolerance class G, plate size 02 and plate thickness 01 make the insert suitable for common negative clamping systems and standard toolholders used in turning and boring operations. The product belongs to the Walter Schneidstoffsorte - Serie offen, offering straightforward procurement and inventory management for industrial workshops. Planners and operators benefit from the insert’s clarity of specification when matching it to holders and machines: the precise geometry and defined chipbreaker reduce trial-and-error in process set-up and support quicker ramp-up times for new production runs.

FAQ

What materials is this insert suitable for? The WCGT020102-FN2 WNN10 insert is a coated hardmetal grade; suitability depends on the specific workpiece material and cutting data. Consult the product matrix to confirm compatibility for individual steels, alloys or non-ferrous materials.

How does the FN2 chipbreaker affect machining? The FN2 chipbreaker promotes controlled chip formation and evacuation, which reduces the risk of chip entanglement and supports consistent surface quality when using the WCGT020102-FN2 grade in turning and light boring operations.

What does the 0.2 mm corner radius mean for finish and tool life? A 0.2 mm corner radius provides a compromise between edge strength and surface finish: it supports finer surface quality in finishing passes while still offering sufficient edge robustness for routine production use.

Is there a recommended relief angle for holder selection? The insert is specified with a 7° relief angle; selecting compatible negative toolholders and correct seating ensures optimal clearance and consistent cutting action for the WCGT020102-FN2 WNN10 insert.
