Dremel

Dremel (/ˈdrɛməl/ DREM-əl) 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, an Austrian immigrant who founded the Dremel Company in 1932 in Racine, Wisconsin.[2] The company was purchased by Robert Bosch GmbH in 1993, 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
1947 advertisement for the Dremel Moto-Tool

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 the high torque of a conventional power drill. 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. The thread of the drive shaft on similar rotary tools tend to be manufactured to similar but slightly larger metric dimensions[3] which are incompatible with the Dremel standard thread diameter of 0.28 inch with 40 TPI.[4]

Approximate Dremel type spindle and collet/nut arrangement

However, the collets are flexible and will accept both original Dremel and alternative makes of cutting, grinding, and polishing head shafts.

Other tools

Dremel produces hot glue guns, scroll saws, contour sanders, versatips, and powered screwdrivers.

Dremel is also one of the manufacturers to release an oscillating tool in late 2008 after the patent had run out on Fein's Multimaster. Dremel's incarnation of this tool is called the Multi-Max.[5]

Dremel also produces 3D printers.
