GB/T 1142-2004 specifies the dimensions, tolerances, and technical requirements for shell drills, which are cutting tools used for enlarging pre-existing holes in metal workpieces. It is applied in manufacturing and machining industries, particularly for precision boring operations on lathes, milling machines, or drilling machines where interchangeable shell-type drill bodies are mounted on arbors. The standard ensures interchangeability and consistent performance across tooling systems in industrial production environments.
