Toolholder for supporting thin rotary tools

Abstract

A toolholder for supporting thin rotary tools is disclosed, utilizing first and second tool rings having flange portions for respectively clamping and driving the sides of a rotary tool such as a thin grinding wheel, wherein the respective tool rings have generally circular tool support sections adjacent to their flange portions, and the circular tool support sections are relieved so as to form facial teeth or lugs on the two rings, and the respective teeth of the one ring engage the tooth spaces of the other ring and vice versa, when the rings are clamped against a thin tool. The first tool ring is adapted to locate and drive with a rotatable tool spindle, and the second tool ring is adapted to be carried in a concentric manner with the first ring and means is provided for clamping the rings together and enmeshing the respective tool support sections, so that a tool having a thickness equal to or less than the combined length of each tool support section of the respective rings may be clamped and supported on a substantially continuous bore support surface.
