Dremel is a bran of tools, primarily rotary tools, developed by Albert J. Dremel, who founded the Dremel Company in 1932 in Racine, Wisconsin. In 1993 the company was purchased by Robert Bosch GmbH, and today it is a division of the Robert Bosch Tool Corporation and located in Mount Prospect, Illinois. Dremel rotary tools may be likened to the pneumatic die grinders used in the metalworking industry by tool or moldmakers.
