This handle system from Robert Sorby is designed with the woodturner's needs in mind. Each handle is made from aluminum with a comfortable foam grip. Each handle has a 5/8" hole with two set screws that hold the tool securely. The length of the tool can be adjusted. Two Collet Adaptors are included with each handle for holding 1/2" and 3/8" tools. An optional Collet Adaptor is offered for holding 1/4" tools. The handles measure 16" or 22" by 1-3/8" diameter. They can be combined into a single 38" handle with the optional coupler. The end cap of each handle can be removed and fitted with an optional counterweight and an optional side handle is available to allow for extra control.
