  • Patent number: 8052156
    Abstract: A bit holder includes a shank, and a bit sleeve. The shank has a first end portion of a non-circular geometric equiangular cross-section for combining a hand tool, and a second end portion formed with a combining hole having female threads in its wall. The bit sleeve has a through hole for a bit to extend therein, male threads and a circular circumference. The bit sleeve is combined with the shank by engagement of the male threads with the female threads, and the bit sleeve may be rotated to fix with or loosen from the shank by an auxiliary tool for changing the bit. In assembling, the bit is inserted through the through hole of the bit sleeve, and then the male threads of the bit sleeve are engaged with the female threads of the shank by an auxiliary tool fitted with the circular circumference and rotated to keep the bit combined with the shank, with the bit sleeve pressing the bit so as to minimize the tolerance of the gap between them, thus enabling the bit to drive a screw smoothly into an object.
