Abstract
A hand held nibbling machine has a manipulatable housing with a drive head in which there is a downwardly opening passage. A tool assembly has an upper portion extending into the passage of the drive head, a lower portion for supporting a die, and a neck portion therebetween providing a throat portion between the upper and lower portions and into which a workpiece may extend. The upper portion of the tool assembly is releasably engaged in the passage of the drive head by interengaging surfaces about a portion of the outer surface of the upper portion of the tool assembly and about a portion of the wall of the drive head defining the passage, and these surfaces are disengageable by rotation of the tool assembly within the passage to move the interengaging surfaces out of alignment. A releasable fastener in the drive head is engageable with the upper portion of the tool assembly to secure the tool assembly in a rotated position in which the surfaces are interengaged.
