Product Information
Description
The small Ball and Radius Turning Tool, like its larger counterpart, is designed to cut round shapes or curves in brass, aluminum, steel, wood or plastic on your own lathe. Balls in the ends of rods, shafts, or handles are easily turned with the tool. You can also make ball joints, governor weights, railing knobs, round contact points for tools, nose cones, and many other useful and decorative objects.
On most lathes, the Ball and Radius Turning Tool will fit in standard tool holders. The tool is designed so that the center height is 1/4" from the bottom of the shank, so that on lathes like the Sherline or Taig, which use a standard 1/4" tool bit, little or no shimming is needed. On other lathes, the tool can be easily shimmed to center height. The tool comes with a pre-ground HSS tool bit which may be easily sharpened or modified.
This tool is manufactured from the highest quality materials. Frames and handle are machined from high strength aluminum alloy. The pivot pins are hardened and ground and rotate in custom bronze bearings. The tool is completely machined from solid metal stock, there are no stamped, cast or pressed parts. A pre-ground High Speed steel tool bit is included. Each lathe radius turning tool is manufactured in the USA for LittleMachineShop.com by Belfanti Toolworks and is carefully assembled and inspected before shipment in our warehouse.
