10pcs 0.5-3.2mm Precision Brass Mandrels for Dremel Drill Electric Chuck Rotary Tools

Dremel is an American company based in Racine, Wisconsin. It was founded by Austrian inventor Albert J. Dremel, the man with 55 patents. This versatile genius filed patents for inventions as diverse as electric erasers, electric fish scalders and the very first electric lawnmowers. His first invention was the electric razor sharpener, which enabled him to develop a device that would be used for many purposes: the high-speed rotary tool. Dremel went on to become the undisputed leader in the hand-held power tool segment. From planers to jigsaws, all Dremel tools derived their performance from high-speed rotation, and not from torque as with other brands; what's more, the rotational movement could be applied to multiple tasks, which enabled Dremel to create multifunctional tools, very practical for any complex DIY activity. Albert J. Dremel was also ahead of his time in terms of management, by involving his employees in the company's results. Even today, Dremel has a market share of 80% of the European mini rotary tool market. In the 1990s, it was the first American company to use lithium-ion batteries, well ahead of the others. Dremel was bought out in 1993 by Bosch, one of its most innovative competitors.
