    • Great for nail trims
Style: Original Kit
This is a work horse. Used in a small animal hospital for nail trims. We do many on a daily basis and the battery lasts a long time. It is slightly heavier than the last device that we had, but not too heavy. It has varying speed controls, but we usually use it on high. Easy to use and great value for the money. ... show more

    • Reliable and great battery power
Style: Original Kit
Great product. Just limited accessories so had to buy more to take full advantage of the tool.

    • works well
Style: Original Kit
it is a little bit better powered than the 8220 it is replacing. brushless always works better. Not sure it is worth the extra bucks, though..... it does work fine. just cut thru a couple 1/4" steel bolts with it

    • Great tool to have
Style: Original Kit
Love this tool - great for detail detail work and battery lasts a long time too. You do have to completely remove the collet to change rotary cutting bits. Tried using the optional drill chuck but it's not designed for these heavier load uses.

    • Decent battery driven Dremel but is rather bulky and heavy.
Style: Original Kit
Powerful battery version of the venerable Dremel high speed rotary tool. I used this where using my 120V Dremel was inconvenient to use. I have a full set of tools etc. to use with the Dremel as the ones provided with this battery driven tool are minimal. Pros: 1. Well made. 2. Provides same facilities as the 120 V tool (but does not fit the vertical drill stand). 3. Batteries provide a reasonable life. 4. Easy to use. 5. Nice case with minimal starting tool set. 6. Batteries charge quickly. Cons: 1. Heavy and bulky when compared to the 120 V tool. 2. Minimal tools provided with the tool if you are new to Dremel. 3. Speed control does not go from 0 rpm, once powered on the tool is running at reduced revs. Summary: Recommended with the proviso that this is rather large and heavy and not as easy to use on small projects. ... show more

    • Great tool
Style: Original Kit
Great portable tool. I use it for all sorts of tasks. From automotive, to 3d printing and anything inbetween. Lasts for a good while. Lots of attachments that can bought separately.

    • The King of Rotary Tools
Style: Original Kit
Incredibly versatile and has excelled in every task I’ve given the tool so far. I studied all the other Dremel models and other brands, and this one checked all the boxes for me. I highly recommend looking at videos about the MANY different Dremel bits and accessories before buying. I do highly recommend the Flex shaft. ... show more
