The Ultra-Shear .59 Square – 2" Radius Insert adds control to shaping work while keeping the stability of a square edge on a woodworking lathe. The eased corners change how the insert enters the cut, reducing abrupt contact and allowing smoother movement during shaping passes.

This insert uses a nano-grain carbide structure that supports a refined cutting edge while holding its form through repeated use. A polished cutting face helps the tool move through material with less resistance, and the bevel is ground to maintain consistent edge geometry as the insert is rotated. These elements work together to keep the cut steady and predictable when working across outside profiles.

The moderate radius helps the insert track cleanly through transitions and maintain continuous edge contact. It supports shaping and light refinement steps without interrupting the surface, making it a practical option for general turning work on a wood turning lathe.

Nano-grain carbide supports a sharper, stable cutting edge
