Abstract
A torque transfer assembly for a bit holder includes a first lateral member, a second lateral member and a coupling pin. The first and second lateral members extend substantially parallel to each other along opposing sides of an axial channel of a base portion of a drive body of the bit holder. The drive body includes a drive end configured to interface with a powered driver. The coupling pin interfaces between the drive body and a driven body of the bit holder to transfer torque between the drive body and the driven body via engagement between the coupling pin and the first and second lateral members.

An impact bit holder comprising:
- a drive body having a drive end configured to interface with a powered driver, the drive body comprising a base portion;
- and
- a driven body having a driven end configured to interface with a bit,
- wherein the base portion of the drive body interfaces with a coupling pin interfacing between the drive body and the driven body as an elastic torque transfer assembly configured to transfer torque between the drive body and the driven body via the coupling pin.
