The 360-degree grip zone for every position, the 6 foot cord and the sliding speed dial which allows the RPM to be set from 5,000 to 35,000 make it easy for you to customize your approach to your project with uncanny precision.

And if something should happen to it, no need to worry; the Dremel 4000 comes with a 5-year warranty.


  • Modestly priced for the amount of accessories and additional compatibility it boasts.
  • Durable, practical carrying case for safe and easy transport.
  • Tool speed setting remains constant due to electronic feedback circuitry and improved motor.
  • Very light and easily managed tool.
  • Circle Cutter/Straight Edge and Sanding/Grinding Guides for impeccable results.


  • The speed dial can be hard to manage; power/speed management will take some getting used to.
  • Output shaft lock can become jammed
  • Prolonged activity can cause it to feel very hot – very common in Dremel designs in general with the placement of its side vents/cooling system


The Dremel 4000-2/30 Rotary Tool is definitely a very powerful rotary tool. It might be a tad too powerful for light use and day to day jobs. It definitely is durable and will last a long time for more powerful jobs. It is very useful for just about anything you want to do, though it might be a tad too powerful for light use and day to day jobs – other than that, this is a very powerful and versatile Dremel rotary tool.
