The bit tang has a double taper that fits in a notch inside the shell chuck.

Specialized Holt bit tangs could be purchased from the manufacturer.
This bit has one of the Holt tangs forged welded onto an Irwin solid-center bit.

A special adapter could be purchased that allowed standard bits
to be used in a Holt brace.

Many kinds of boring and drilling tools were offered with Holt tangs.
On the left is a countersink, in the middle a metal drill bit, and a large
