The exact year of production of the drilling machine is unknown, most probably at the end of the 19th century. For many years he used to work in the arsenal workshops of the Austro-Hungarian army in Ljubljana, where the Kunavers bought the machine after the end of World War I. Without a doubt, Drill 14 is one of the first metalworking machines in the Kunaver workshop. It was designed as a vertical pillar drilling machine with manual drive. This machine was then electrically powered and a special accessory was added, which also allowed for milling. This device was able to produce simple gear wheels up to a module of 1.5.

Kunaver's mechanical metalworking workshop has been operating since 1928 in Rožna dolina in Ljubljana. Her machine park, however, has been changing over the decades. In order to be able to operate at all in this family workshop, individual machines were designed and manufactured by themselves, or purchased and reworked to fit the nature and scope of the work. Some machines from the first half of the 20th century have been preserved to this day, others have been sold. After the workshop was closed ing. Janez Kunaver donated some of the machines to the Technical Museum of Slovenia.
