This manufacturer of drill sharpening grinders was established in Beecher, Illinois, in 1973. The first three letters of the company name represent the first names of David Bernard, his grandfather Arthur, and David's father Richard. The company co-founders were David and Richard; Arthur had established a welding company where the co-founders began. In 1978 Darex moved to Ashland, Oregon. They continue in business, making a broad range of drill sharpening machines and the Darex and Drill Doctor brands. They also make the Work Sharp line of grinding systems for woodworking and metalworking tools.
