Abstract
A bit holder is provided which includes a body having a cavity formed with an upper portion and a lower portion, separated by a ridge-like protuberance which has a cross sectional profile smaller than that of the upper portion and the lower portion. The ridge-like protuberance is formed on each sidewall of the cavity to form an interference fit. A method of manufacture includes the use of a punch to force material from the upper portion downwards towards the lower portion of the cavity to form the ridge-like protuberance.
