Almost everyone I know has at least one version of a Dremel rotary tool in their arsenal of tools, so when Dremel sent me one of their new Trio units to test out I was pretty excited. They claim that the Trio has “360 degree cutting technology”, which means that it can cut in any direction, no matter how the tool is orientated. Dremel also calls the Trio part sander, part mini rotary tool, and part jigsaw, but how well will it actually do all of those things? Will the Trio be a replacement for any of those tools, a nice compliment, or will it just sit in its case collecting dust? hit the jump to read the full review. Compare this with our RIDGID JobMax review for your tool upgrade.

As a homeowner there are always little jobs and projects to complete, and the ability to use one tool to do the work of many would be a great boon – however as I quickly learned just because something can do something, doesn’t mean that it should.  To start out with, I was remodeling my bathroom, and wanted to put a wood border around my new vanity, so this was the perfect opportunity to test the jigsaw functionality of the Trio.

I found that the jigsaw area is where the Trio truly excelled rather quickly when I wanted to cut a rectangle out of a board.  With a normal jigsaw, if you wanted to cut out a shape from inside of a piece of wood, you would have to first drill a pilot hold, and then insert the jigsaw blade in the hole to cut.  With the Trio, you just plunge and go – rather than using a drill and then a saw, you just use the Trio, and you don’t even need to change the bit.  You definitely need to watch the speed you set it at though, because high speeds just rip through soft wood.

After that, I needed to sand down a bit (because I had the speed a bit too high for my first cuts), so I used the Trio for that as well.  It really performed as well as I expected it to – every other Dremel rotary tool does sanding though, so it’s no real surprise they got that right.  With the Trio you could potentially get rid of your other rotary tools though – I was even able to knock the tips off of a few nails that were too long for my deck with no problems.

Speaking of my deck, I wanted to try the router function there, and here’s where my issues with the Trio come into play.  Every company that makes router bits makes them with a 1/4 inch shank – Dremel in their infinite wisdom decided to make the Trio take a 3/16 inch shank.  Even more irritating, Dremel themselves make a six piece routing kit, but the kicker is that the kit is for the normal Dremel tools and all the bits have a 1/4 inch shank!  I did manage to get one of the tiny routing bits they make for the Trio, and it does work, but that’s the one area you would be better suited just buying a standard router.

Overall, the Trio by Dremel is a pretty good tool, and would be well suited in any DIYer’s toolbox.  While it’s only 2 amps, it gets between 10,000 and 20,000 RPMs depending on what power setting you use.  That’s plenty strong enough to tackle most light jobs, but you just need to remember that while the Trio can do the work of all three other tools, it won’t be able to completely replace them for the heavier stuff.


  • Versatile tool
  • Can work in tight spaces
  • Cuts at any angle


  • Not as good as having dedicated tools
  • A bit of a learning curve with soft wood
  • Only using a 3/16 inch shank is horrible

I give the Trio by Dremel a 3 out of 5 because while it’s nice to have one tool to do multiple things, sometimes it’s not practical.

You can purchase the Dremel Trio from Amazon for $80.44

  1. The tool is kind of well intended in inception but, the story of the accessories was handled by a lobotomized corporate individual with a body only with two extra butts in the skull…

  2. Like all rotary Dremels, the Trio is a hobby tool. Used as intended, it is great. It was not intended to be a Sawzall or a Rotozip but, with patience and a lot of time, it will do their job better than they will do the job of a Trio.

  3. I brought the trio as a combo pack with multi tool. Everything works fine but the Trio. Finally threw it away the other day. So disappointed in dremel about this product. Just don’t think it’s ready for prime time yet.

  4. I can see the frustration people may have with this tool and the lack of accessories, however if you search for TRxxx accessories, you’re guaranteed to find 3/16″ bits.

    That said…I received this in the Dremel 3-pack (with the 300 series, and the Multi-Max) and used this to cut precise cuts in drywall with ease.  They have bits to cut stronger materials, but didn’t include it in the kit, but for the convenience of making detailed cuts quickly, I am impressed with this tool.

    Like the author wrote, it’s not going to replace dedicated tools, but for homeowners who are DIYers, this fits nicely into my arsenal.

  5. It’s practicality is limited to small scale projects. The tool is instable at higher speeds and prone to breaking when used for bigger projects that it was designed to do, especially the collets which are near impossible to find.

  6. This is my 3rd Dremel tool. Well, needless to say, I still have not learned to use it. I’ve TRIED to use it as a jigsaw and as a router, and I was highly disappointed. It or maybe I just seem to make a mess with it. I can not use it at all. So, it stays in the box. Maybe I will try again after reading these reviews. Maybe I had it turned up too high. I might slow it down a little and give it another whirl. Overall, right now, I HATE it.. it was a total waste of money……..

  7. it really ony a hobby tool i tried one  it would not work half as good as a jigsaw to cut curves shapes or what ever its a rotating cutter  ok it will plunge into workpiece  a jigsaw cant do that      the dremil would not follow the curve line  freehand it took its own path  i just put it away and used the jigsaw its blade works up & down and it cuts pretty good to a given line with ease   it ok sanding     a no for me

  8. i just bought a dremel trio ,thinking i could buy more cutting accessories at a later date.don't . i was very disappointed  there wasn't anything available in a 3/16 shank . seems like there should be a selection of collets  to fit in the same nut like one of the smaller dremel tools have .is that possible ? i would have to give the  trio 3 out of a possible 5

    1. I’d give this tool a 1 out of 5 based on the fact that there are NO accessories for it….Don’t waste your time or money with this tool. It will sit in your tool shed to collect dust. Mark my words
