The utility model provides a small combined machine tool integrating drilling and slotting operation into one body, which solves the problem that the above two machining operations are respectively independent in the prior art and are performed through two different types of devices with excessive accessories and larger occupation space. There are numerous machine tools, producing round holes, but many components in engineering require square and non-circular holes. In the present day situation, square holes and non-circular holes are produced using CNC Machines or Spark Erosion or Slotting Machines. A quality machine tool to produce square and polygonal holes are rarely available at low cost. This paper aims to help the small scale production floors where a drilling machine exists and the scope of work extends to be done on a slotting machine also. Using this project slots can be cut on work pieces using a drilling machine. This project is an attempt to design and fabricate an attachment for drilling machine which would produce square and polygonal holes much easier than the currently available methods. This is done by using an inversion of the Slider crank mechanism.
