This radius cutting attachment turns your Proxxon lathe into a shaping tool for convex, concave, and spherical forms. Designed to mount on the cross slide in place of the standard tool holder, it produces radii up to 32mm and three-quarter spheres. The height-adjustable tool holder positions the boring tool tip 30 to 45mm above the cross slide for precise control. Perfect for woodturners working with the PD 230/e or PD 250/e lathes who want to expand their project possibilities.
