Abstract
Abstract An adjustable tool holder having a block portion adapted for mounting on a boring bar or the like. Tool-holding means is adjustably attached to the block portion and movable with respect thereto to vary the relative spacing between the cutting edge of a tool carried thereby and the boring bar to vary the bore diameter. Adjustment means carried in the tool holder is cooperable with the block and accessible from an outer edge of the tool holder so that adjustment may be made without removal of tool holder from the boring bar.
