Machine building expertise through tradition


The history of the family business DEPRAG SCHULZ GMBH & CO. KG goes back to the establishment of the Bavarian Rifle Factory in 1801. The company was already well-known at that time for combining outstanding technical expertise with manufacturing and developing state-of-the-art products. This industrial experience was utilised in the production of tools, measuring gauges, machinery and for the first time, small air operated machines, when the company was integrated into the “Deutsche Werke“ conglomerate in 1918. From these beginnings mechanical engineer Otto Schulz created the

Deutsche Präzisionswerkzeuge AG and began the production of handheld air tools.

In the 50s and 60s DEPRAG enjoyed a very successful period of growth. In 1964, Dipl.-Ing. Carl Schulz, together with his brother-in-law Hans Pfeiffer, took over the management of the company and set the trend for international expansion.

A further milestone was achieved in the global orientation of the company in 1981 with the foundation of the US subsidiary DEPRAG INC. in Lewisville, Texas.

Today, after 90 years, DEPRAG SCHULZ GMBH & CO. KG is managed by the third generation of the Schulz-Hallmann family and by the Pfeiffer family.
