At present, the groove of pipe fittings is mainly for welding workpieces to ensure the welding degree. According to the needs, the angles of each groove are different. Therefore, the use of groove cutting devices is very extensive.

[0003] For example, a pipe bevel cutter with publication number CN216758371U has a wide range of applications. It is suitable for pipes of various sizes and can meet various welding bevel angle requirements. The invention is simple to manufacture and easy to operate, and can be used in various construction sites. Good results have been achieved in actual production.
