Ultra-Shear .59 Square 4″ Radius Insert

The Ultra-Shear .59 Square – 4″ Radius Insert is configured for controlled shaping and surface refinement on a woodworking lathe. The larger edge radius engages the material gradually, allowing the insert to move across the workpiece with a more continuous cutting action.

A fine-grain carbide composition allows the edge to be formed cleanly while maintaining durability through extended use. The cutting face is polished to reduce drag as the tool advances, and the bevel is machined to keep the edge consistent through indexing. This combination helps maintain a uniform cut as the insert moves along curved surfaces.

The increased radius promotes smoother tracking across broader profiles and helps maintain consistent contact through sweeping shapes. It transitions effectively from shaping into surface cleanup on lathe tools where a more controlled cutting path is needed.
