Dremel 4000-6 50 120-Volt Variable-Speed Rotary Kit

Our Rating: 4.5/5 ★★★★½ 

The Dremel 4000 Rotary Kit is not your normal Dremel tool. It delivers smooth performance at speeds from 5,000 to 35,000 RPM. Yet, it is slim, and ergonomically designed to provide a 360 degree grip zone in every position. There is a variable-speed slide that allows for both fast speed adjustment, and consistency at your selected speed. You don’t have to worry about the on/off switch either because it is strategically placed where it won’t interfere with your grip.

If you don’t know what all a Dremel tool can do, you may be surprised to learn it can perform functions such as carving, engraving, routing, grinding, sanding, cutting, cleaning, and polishing! This particular Dremel, the Dremel 4000 Rotary Kit, is lightweight and user friendly. It has a six-foot cord, pencil-grip nose cap for stability, and replaceable motor brushes. Weighing in at only one pound, you should be able to work all day without too much strain on the wrists, arms, or hands.

Some special features of the Dremel 4000 Rotary Kit are the fact that it’s the only rotary tool compatible with all Dremel accessories and attachments.
