WNMA 080408 T5105 trigon turning insert by Tungaloy — CVD-coated carbide, 80° cutting geometry

The WNMA080408 T5105 is an ISO‑standard turning insert engineered for stable, high‑speed external and internal turning operations, optimised for machining cast iron under steady conditions.

• CVD-coated carbide for high wear resistance
• Trigon shape with 80° cutting angle
• Corner radius 0.8 mm
• Cylindrical hole for secure clamping

Productive, high‑speed turning where stability matters

This ISO‑normed indexable insert combines a CVD-coated carbide substrate with the T5105 grade to deliver wear resistance during elevated cutting speeds. The trigon geometry with an 80° main cutting angle provides a balance between robustness and accessibility for external and internal turning tasks. In practical terms, this means longer tool life and fewer interruptions for insert changes, which supports continuous production and reduces downtime in batch and series machining.

Precise geometry and clamping for reliable results

The insert’s trigon form and the cylindrical hole enable secure and repeatable clamping in compatible holders; compatibility is defined by form, clearance angle, tolerance class, fastening method, size and thickness. The 0° clearance angle is a neutral geometry parameter that relies on the holder’s set‑up to establish the effective cutting clearance; when combined with an appropriate external holder or boring bar, the assembly gives predictable chip flow and dimensional consistency across components.

Small radius, big impact on surface and tool life

A corner radius 0.8 mm reduces edge vulnerability while still permitting fine wall finish and dimensional control on cast iron components. The moderate radius supports stable chip formation without excessive cutting forces, which is particularly valuable when the machining set‑up is rigid and vibration is minimised. For production engineers this translates into reproducible surface quality and fewer rejects, while maintenance teams benefit from predictable insert change intervals.

Material suitability and application tips

Designed primarily for the high‑speed machining of cast iron, the grade’s CVD coating enhances resistance to abrasive wear typical of this material. Select the matching chipbreaker and grade according to workpiece material, machining strategy and machine stability; the insert is intended for both external and internal turning when used with a compatible ISO holder, locating pad and correct clamping hardware. Where finishing or polishing is required, combine the insert’s geometry with lower feeds and tailored coolant strategies to optimise surface outcome.
