Abstract

A holder block and pick assembly including a pick, a washer, and a block body. The pick includes a shoulder and a shank extending rearwardly from the shoulder and having a diameter smaller than the diameter of the shoulder. The washer has a central opening adapted to fit about the shank adjacent to the shoulder and a substantially flat edge disposed substantially perpendicular to a radius of the central opening. The block body includes a bore for receiving the shank, a base surface at a lower end of the body for mounting the body to a rotatable element of a rotary cutting machine, and a stop extending frontwardly from the front face of the body and having a surface located substantially perpendicularly to a radius of the bore such that when the pick shank is inserted into the bore with the washer disposed about the shank adjacent to the shoulder, the flat edge of the washer engages the surface of the stop to substantially prevent the washer from rotating with respect to the block.
