ABSTRACT:
A tool having a housing with a plurality of bits located within the housing. Each bit has a working end to protrude from the housing and an inner end in the housing. There is a pathway in each bit adjacent the inner end. An opening in the housing allows a bit to protrude. That bit can be gripped to hold it in place. Second openings are positioned in the housing and shafts extending through each second opening and through a pathway in a bit. Each bit is urged radially outwardly, for example by a spring. A bit may be selected by pushing on its shaft and moving the shaft downwardly towards the opening. The bit is then gripped in place with its working end protruding from the opening in the housing.
