Dremel is an American brand of power tools known primarily for its rotary tools. Dremel's rotary tools are similar to the pneumatic die grinders used in the metalworking industry by tool or moldmakers. The tools were originally 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 located in Mount Prospect, Illinois. Dremel's activities in Europe, the Middle East and Africa are operated by Dremel Europe, located in Breda, Netherlands. == Rotary tools == The concept of the original Dremel Moto-Tool was to rotate a bit at high speed; the bit being held in a collet. Variable-speed versions may cover a range of 3,000–37,000 RPM. The Dremel concept relies on high speed as opposed to torque unlike a conventional power drill, for example. By inserting an appropriate bit (or burr) the tool can perform drilling, grinding, sharpening, cutting, cleaning, polishing, sanding, routing, carving, and engraving. Both battery-powered and corded models are available. (Early cordless models were marketed as the Dremel Freewheeler.) Dremel options include a miniature planer attachment and a saber saw attachment that lets the tool act much like a small reciprocating saw. Other Dremel rotary tools include a cordless pumpkin carving tool, a cordless pet nail grooming tool, and a cordless golf cleaning tool. Similar rotary tools (for example, those sold by Sears under their Craftsman brand) are also sometimes colloquially called dremels in an example of a genericized trademark. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dremel」の詳細全文を読む スポンサード リンク
