摘要：
A guard ring having a center bore mounts on a face of a spindle of a machine tool having a taper socket drive, and a bore for receiving and driving a tool holder. A drive between the guard ring and the tool holder engages before a power drawbar of the machine tool spindle engages the tool holder. The guard ring is of an axial length such that the tool holder is within the center bore of the guard ring before the tool holder is driven by the power drawbar of the machine tool.
