The story of LOCH Präzisions Bohrtechnik GmbH is not just the story of an ambitious family business which manufactures particularly robust deep hole drilling machines. It is also the story of the Loch family. What started during the Second World War in 1943 as a four man business is today a company that operates on a global scale. More than sixty years of experience in manufacturing, the thin and flexible structure of a family business, as well as the continuous further development of high quality deep hole drilling machines in accordance with the most up-to-date standards are the reason and a warranty for the high quality of the products and services offered by LOCH Präzisions Bohrtechnik GmbH, right up to now.

In 1974, the cornerstone for founding the company Loch GmbH was laid. Since 1983, LOCH Präzisions Bohrtechnik GmbH has been specialising in the manufacture of custom built deep hole drilling machines as well as in "deep hole drilling" manufacturing technology. The company moved into their newly built company headquarters in Ergolding in 1986 and in 1996 it was certified in accordance with DIN EN 9001. Just a few years later in 2001, the newly built manufacturing hall for contract manufacturing was put into operation and since 2002 LOCH Präzisions Bohrtechnik GmbH has been certified in accordance with DIN EN 9001/2000.
