The Dremel rotary tool eliminated the need for workers to set up multiple dedicated power tools to complete complicated assignments.Ī modern rotary tool kit consists of an ergonomically designed base with a variable-speed electric motor, a universal attachment spindle, and a wide selection of bits and blades. He developed a multi-purpose tool that featured a handheld rotary motor and a variety of blades and bits. Dremel took that concept one step further after World War II. These are all considered rotary tools, but an inventor named A.J. A motor produces a variable rate of spin, and a specialized blade or bit performs a task, whether it be slicing through a piece of wood, boring a hole in sheet metal, or grinding down a burr. Many common power tools, such as a circular saw, drill, or grinding wheel, would fit the broad definition of a rotary tool. Other Dremel rotary tools include a cordless pumpkin carving tool, a cordless pet nail grooming tool, and a cordless golf cleaning tool.Circular saws and grinding wheels are also rotary tools, but not nearly as versatile as the multi-purpose Dremel. Dremel options include a miniature planer attachment and a saber saw attachment that lets the tool act much like a small reciprocating saw. Early cordless models were marketed as the Dremel Freewheeler. Both battery-powered and corded models are available. By inserting an appropriate bit (or burr) the tool can perform drilling, grinding, sharpening, cutting, cleaning, polishing, sanding, routing, carving, and engraving. The Dremel concept relies on high speed as opposed to the high torque of a conventional power drill. Variable-speed versions may cover a range of 3,000–37,000 RPM. The concept of the original Dremel Moto-Tool was to rotate a bit at high speed, the bit being held in a collet. Different tools products range in speed from 3,000 to 37,000 RPM. Dremel Multitools work by using speed instead of torque. Many different accessories and attachments are also produced. Dremel rotary tools are suitable for carving, engraving, routing, grinding, sharpening, cleaning, polishing, cutting and sanding. Over its history, Dremel has created over 30 different designs and models, mainly for home improvement and hobby use. The company currently produces six rotary tools, three corded and three cordless. Dremel's activities in Europe, the Middle East and Africa are operated by Dremel Europe, with its headquarter located in Breda, Netherlands.ġ947 advertisement for the Dremel Moto-Tool die grinder The main office of Dremel US is located in Mt.

It is also used by podorthists for use on shoe inserts, and dentists use them for crafting dentures.ĭremel said in 2013 that there were more than 17 million of their rotary tools in use. Military doctors used the tools in dermal abrasion techniques to reduce scar tissue from battle wounds. In the 1940s the Defense Department reportedly used Dremel rotary tools in developing the first atomic bomb. People found many ways to use the rotary tools.

Dremel died on 18 July 1968 at the age of 81. In 1948, Dremel gave his employees a 3% year-end share of profits, at the time seen as a radical idea. This invention was successful in the hobby and craft market. Dremel then developed the high speed lightweight rotary tool, later named the Dremel Multitool, for which the company continues to be known. His first product released within the company was an electric razor-blade sharpener, which lost popularity when cheap disposable razors became available. Dremel held 55 patents across a wide range of inventions, including an electric eraser, electric fish scaler, electric shoe polisher, electric screwdriver, power sanders, scroll saws, a device to monitor chicken's egg production, and first design of the now standard walk-behind rotary lawn mower. Dremel in 1932, the company is located in Racine, Wisconsin, US. Founded by the Austrian inventor Albert J.
