The Ultra-Shear .59 Square Insert is built for woodworkers who expect more from their lathe tools. Developed through extensive testing, this insert uses a nano-grain carbide matrix that supports a sharper cutting edge and longer usable life than standard carbide inserts.

The cutting surface is polished to a mirror finish, and the bevel is precision ground. This combination reduces resistance at the cut and helps maintain control during shaping and material removal. The fine-grain structure allows the edge to be formed at a sharper angle without breaking down, so it stays effective through repeated use on a woodworking lathe.

The square profile provides a strong, straight cutting edge suited for general turning work. It removes material efficiently in early stages and maintains clean contact when refining shapes. Paired with the Ultra-Shear Carbide Turning Tool, it delivers a consistent cutting action that helps reduce sanding time and improves surface quality across a range of projects on a wood turning lathe.
