Probably the most interesting highlight for the 4000-3/34 is the unique Detailer’s Grip that it comes with. This is a handle that you can attach to the front of the rotary tool, which allows you to grip it at a right angle. The Detailer’s Grip makes it so much easier to work at those small, hard-to-reach areas, which is perfect for things like engraving, and fine carving. Being given the option of working at things on a larger scale or a smaller one means that you don’t need to switch tools while undergoing any task; spend time tackling the bigger issues first, then use the Detailer’s Grip to get in and finish up the little ones.


  • Detailer’s Grip makes fine engraving a much easier task
  • Electronic feedback circuitry keeps set speed constant
  • 360-degree grip zone for comfort and flexibility
  • Replaceable brushes for motor ensures device longevity
  • Quick output shaft locking mechanism makes switching accessories easier


  • Device may tend to overheat
  • Selected speeds may not stay accurate
  • Not recommended for commercial use, not as heavy duty as other Dremel kits (like the Dremel 4000-2/30 rotary tool kit)


The Dremel 4000-3/34 Rotary Tool is among a select few mini rotary tools that could be considered a near-perfect selection for its category. Its many functions and possible uses guarantee that you’ll be keeping it handy for a long time to come. It doesn’t operate well in heavy duty settings, but so long as you utilize it within appropriate situations, you’ll be glad you bought it. And for the price, it definitely delivers on quality and durability.
