Abstract
A holder is provided for attaching a tool, having a tapered end and a flat driven face on the end, to a rotary drive, such as a drill. The holder has a body with a bore coaxial with the rotary axis. The bore is tapered at one end for slidably receiving the tapered tool end and typically is threaded at the other end for receiving the threaded end of an adapter. The other end of the adapter has six sides for attaching the tool holder to the drill. A flat driving face is provided at the tapered bore for engaging a complementary driven face formed in the tapered end of the tool. The tool is secured axially within the tapered bore by a latch element which extends into the tapered bore to engage a recess in the tapered end of the tool. The latch element can be a pivotal latch plate mounted for movement in a radial plane or a radially extending detent assembly. The latch element can also be magnetic.
