The utility model relates to an integrated box for tools and agents for metallographic detection. The integrated box comprises a box body. The interior of the box body is separated into a tool box body and an agent box body. A tool box cover and an agent box cover are arranged on the top of the tool box body and the top of the agent box body respectively. A magnetic base with a rotating handle is arranged at the bottom of the box body and comprises a left magnetic base and a right magnetic base which are independently separated from each other. The right side face of the left magnetic base and the left side face of the right magnetic base are arranged to be opposite arc-shaped faces. The integrated box for tools and agents for metallographic detection has the advantages that different tools and agents can be placed in all compartments respectively and are clear at a glance, the tools are prevented from being left behind on the site and are more convenient to carry, and working efficiency is improved; because the magnetic base is installed, the integrated box can be placed on a pipeline stably and is within reach of an operator, the operator does not need to bend down when taking or putting the tools, and thus working efficiency is greatly improved; the tools and the agents are placed in the box bodies respectively, the tools are prevented from being corroded by the agents, but the box bodies are connected with each other, and thus the integrated box is convenient to carry.
