Abstract
A rough boring tool is composed of a boring rod having a tool hole which is provided with a base line and a plurality of reading scales. The rough boring tool is further composed of a boring tool engaged with the tool hole and provided with a plurality of measuring scales corresponding in location to the reading scales and forming an angle with the base line. The advancement quantity of the boring tool can be easily observed with the naked eye by converging the reading scales of the tool hole of the boring rod and the measuring scales of the boring tool.
