Impact resistant tool bit and tool bit holder

摘要

An impact resistant tool or tool bit holder (10) has an active end (12) for driving a fastener and a shanking end (14) for securing to a power tool. The active end includes a body (16) with a bore (30) to receive the shank (18) and a pocket to receive a damping mechanism. The shank (18) includes an end to engage the bore in the body, and a pocket (44) to receive the damping mechanism (50). The shank (18) is received in the bore (30) in the body (16) for limited rotation with respect to the body (16). A damping mechanism (50) is positioned in the pockets to provide damping between the body (16) and the shank (18) during torque loading.
