Pros and cons

According to our multi-tool expert
  • Thanks to the rotating movement, you can use the multi-tool for precise work like engraving and polishing.
  • After use, you can neatly store the multi-tool in the included pouch.
  • You have an extra good view of your work with the built-in light.
  • You barely feel the 1.5m/s vibrations in your arm, so you can comfortably work for a long time.

A versatile light and handy device to use.

  • Fairly light to hold for a long time.
  • Cord is quite long which gives more room to move.
  • Information in booklet/map is a bit of a search.

  • Can my wife do more jobs now

I'm getting more and more attached to my Dremel.
What once started with the purchase of a multi-tool from an unknown brand, has been converted into the purchase of this Dremel. This after quite a lot of frustrations with the previous multi-tool. Yes, it was rechargeable, but the power and smoothness of this wired Dremel is amazing.
It is precisely those jobs where a jigsaw, circular saw are much too big to use.
Or simply because there is no other device that can get the job done.
For example, I just installed a cupboard wall where the plinth (made of wood) had to be shortened. It's already on the wall. No idea what other device could have shortened it to the right size.
Or think of new sockets. These had to be replaced at some point. The Dremel made sure that the stucco that was around the old sockets was expertly removed so that the new ones fit nicely. But also remember the screws to secure the interior. These were way too long. Ideal for shortening them with the grinding wheel. Tried previously with a hacksaw. Give me the Dremel.
Pros: the large amount of accessories available (although you can do a lot with the supplied accessories), the power of the device, the solid quality and definitely the SpeedClic mounting for some discs. Ideal.
Are there no drawbacks? Yes, some people may indicate the price. But that's relative. I have now previously spent money on a cheaper model that I will never use again. Good tools have their price. If you spread this out over the coming years and the pleasure you get from it, then it's not too bad.

With 35 accessories I initially have enough to tackle most of my jobs. Very nice multi-tool with which I can grind steel with ease and polish away damage. I am curious about the other possibilities and accessories that dremel offers
