摘要:
An improved pick and pick holder assembly for use in mineral winning and the like. The improved pick and pick holder increases the effective life of a tool and pick holder by minimizing the shifting of the pick within the pick holder. The movement of the pick is minimized by front and rear bearing surfaces that remain positively engaged with front and rear bearing surfaces of the pick holder for loads applied to the pick that are predominantly inward and predominantly rearward.
