Abstract (en)
Method and apparatus for hand drilling wherein the reaction torque generated in the hand drill (10) from the workpiece (W) is transferred to a support for the drill (10) and then back into the workpiece (W) to not only divert stress from the operator's body but also to hold the workpiece in fixed position. In one preferred embodiment, the drill support includes a holder (40), means mounting the body of the drill (10) on the holder (40), and an elongated load transfer member (30) on which the holder (40) is mounted for vertical movement therealong. In use, the lower end of the load transfer member (30) is located adjacent the side of the workpiece (W) so that the equal but oppositely directed torques generated in the workpiece (W) and the drill (10) respectively will hold the workpiece (W) fixed against the side of the load transfer member (30) while the torque (reaction) generated in the drill (10) is transferred away from the operator's body to the load transfer member (30) and then into the workpiece (W).
