Any of the two opposite abutting sides spaced at a first distance. Any of the two opposite included angles spaced at a second distance. The socket has first, second, and third sections having first, second and third external diameters, respectively. The second external diameter is smaller than the first external diameter and the third external diameter is smaller than the second external diameter, respectively. A difference between the second and third external diameters is not less than a difference between the first and second distances. A drive bit is mounted to the second end of the socket. ## Claims ### Claim 1 A reinforced drive tool, comprising: a socket having a first end adapted for a user to operate and a second end opposite the first end adapted to be used to drive an object to be driven by the reinforced drive tool, a hole extended along a longitudinal axis and defined at the second end of the socket, with the hole having a hexagonal cross section and defining six abutting sides and an included angle between any of the two adjacent abutting sides, with any of the two opposite abutting sides spaced at a first distance, with any of the two opposite included angles spaced at a second distance, with the socket having first, second, and third sections and each of the first, second, and third sections having a circular periphery, with the first section disposed at the first end and the second section defining a reinforcing section disposed at the second end and the third section defining a neck disposed between the first and second sections respectively, with the first, second and third sections having first, second and third external diameters respectively, with the second external diameter smaller than the first external diameter and the third external diameter smaller than the second external diameter respectively, with a difference between the second and third external diameters not less than a difference between the first and second distances;
