US 2026/0295785 A1 · BIT HOLDER

Abstract

A bit holder may include a coupling portion which may operably couple the bit holder to the driving device, a shank which may extend along an axis of rotation to operably couple to a bit, and a torque adjustment assembly for adjusting a maximum amount of torque in the bit holder. The torque adjustment assembly may include a transfer body which may be operably coupled to a shank of the bit holder, a transfer sleeve which may receive torque from the transfer body, and an adjustment sleeve which may be operably coupled to both the transfer body and the transfer sleeve and may adjust the maximum amount of torque transferred from the transfer body to the transfer sleeve. The adjustment sleeve may adjust the maximum amount of torque by moving the transfer sleeve relative to the transfer body axially along an axis of rotation of the bit holder.

Dependent claims

A torque adjustment assembly for adjusting a maximum amount of torque in a bit holder, the torque adjustment assembly comprising:

a transfer body operably coupled to a shank of the bit holder;
a transfer sleeve operably coupled to the transfer body to receive torque from the transfer body;
and
an adjustment sleeve operably coupled to both the transfer body and the transfer sleeve and that adjusts the maximum amount of torque transferred from the transfer body to the transfer sleeve, and
wherein the adjustment sleeve adjusts the maximum amount of torque by changing a position of the transfer sleeve relative to the transfer body axially along an axis of rotation of the bit holder.
