Abstract: The speed wrench includes a plastic handle and a S-curve shaped shaft with a mount to receive tool driving or drilling inserts. The S-curve shaped shaft causes the axis of the tool to intersect the axis of the handle, thereby causing a cone-shaped pattern of rotation. The shaft permits the user to rotate the handle with wrist motion, thereby rotating the tool insert.
