Abstract: The present invention relates to a portable electric drill having a rotatable magazine containing multiple tool bits from which a single bit may be selected for use. The magazine is in the form of an approximate 120-degree segment of a cylinder with a plurality of open grooves for holding the various bits. The drill includes a Jacobs-type chuck assembly with a bore into which the selected bit is inserted for use. The magazine may be rotated to position any one of the magazine grooves into axial alignment with the bore of the chuck, so that the user may index the magazine to position a selected bit for expulsion from a particular magazine groove into the chuck. The chuck may then be tightened around the selected bit and the electric motor actuated to drive the bit. A cable assembly within the drill housing is operable with an exterior button to be movable between a stored position and a forward position to push a selected bit from a groove on the magazine into the chuck assembly.
