Delta Machinery manufactures several lines of power tools. Delta's history began with its founding as the "Delta Specialty Company" in 1919 by Herbert Tautz. Based at first in Tautz' Milwaukee, Wisconsin garage, the business thrived, first making small tools for home shops and later expanding into light industrial machinery. In 1945, the business, by then known as Delta-Milwaukee, was acquired by Rockwell Manufacturing Company. By the late 1950s, Rockwell had become a powerhouse in stationary and woodworking machinery through expansion of its product line and acquisitions of companies such as Walker-Turner and Crescent Machine Company. In 1981, Rockwell's power tool group was acquired by Pentair and rebranded Delta, the brand that it carries today. Pentair's Tools group was acquired by Black & Decker in 2004.
