Ergonomics include a slim design that provides a 360-degree grip zone for added comfort and control. The Dremel 4000 can use all existing Dremel rotary tool accessories and attachments, as well as high-performance attachments, so you can do more with just one tool. Two year warranty. Maybe I was too heavy-handed, but it was still annoying. The new 4000 stays up to speed far better than my old model. Maybe it’s just the additional power, or maybe it’s Dremel’s newfangled “Electronic Feedback for Consistent Speed Under Load.” Either way, it works!

Many common power tools, such as a circular saw, drill, or grinding wheel, would fit the broad definition of a rotary tool. 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. These are all considered rotary tools, but an inventor named A.J. Dremel took that concept one step further after World War II. He developed a multi-purpose tool which featured a handheld rotary motor and a variety of blades and bits. The Dremel rotary tool eliminated the need for workers to set up multiple dedicated power tools to complete complicated assignments.

A modern rotary tool kits consists of an ergonomically designed base with a variable speed electric motor, a universal attachment spindle, and a wide selection of bits and blades. Some entry level rotary tool kits may only contain a basic set of bits, while advanced kits may include hundreds of attachments and bits. Manufacturers like Dremel also offer specialized add-ons, such as a trimmer blade for pet nail grooming. New blades and bits are constantly being introduced to the marketplace.
