  • The 5 Best Cordless Dremels

    1. Dremel 8220-1/28 Cordless Rotary Tool – Top Pick

    Dremel 8220-1/28

    We think that Dremel 8220-1/28 is the best Dremel made so far. It is compatible with any other Dremel attachment or accessories and is durable and well-made. What makes this model so special is the lightweight and compact size.

    The battery charges within an hour, meaning that you never have to be without it for long. The one caution that we have here is that you need to thoroughly understand what you can and cannot use it for, and also which accessories are required for which projects.

    If you use the wrong accessory or attempt a difficult project, you will not be happy with the lifespan of the battery.

    This kit comes with a carrying case and 28 different accessories.

    This model is cordless, and this makes, in addition to the lightweight and compact size make it a great tool to use.

    The accessories have been changed up a bit in this set, but you can buy an additional set of accessories if you like.

    • Lightweight
    • Cordless
    • Compact
    • A wide range of accessories
    • Will work with older Dremel attachments
    • Highest priced option
    • Battery life can be a problem for large projects

    2. Dremel 8100-N/21 Cordless Rotary Tool

    Dremel 8100-N/21

    This product comes in second to our top pick for two reasons. First off, it is an 8 Volt rather than a 12 Volt tool. Secondly, it does not come with quite so many accessories – it has 18 instead of 28.

    Like the 8220, it is cordless, but this set focuses more on sanding, grinding and polishing. It is around the same size and also features the EZ Twist Nose Cap to make removing and changing the tools a lot easier.

    The model is not as compatible with all of the other attachments as the 8220 is but you can get an accessory to make this right.

    One serious complaint that we have about this model is that it is not good for projects that kick up a lot of dust. The dust seems to be able to get into the switch housing, and this can cause it to overheat.

    • Lightweight
    • Cordless
    • Easy charge battery
    • EZ Twist Nose Cap included
    • Fewer accessories
    • Lower voltage
    • Not going to take all prior accessories

    3. Dremel 8050-N/18 Cordless

    Dremel 8050-N/18

    This is third on our list for a few reasons. First off, it is not as powerful as our top models. Second off, it takes a lot longer for the battery to recharge and third off; you have to change out the accessories using a wrench. It’s not a big deal but is a schlep.

    What is good about it though is that it has LED lighting built into the front to help you see the projects better and an LED speed display complete with a gauge that tells you how much battery power you have left.

    We liked the docking station because it made it easy to charge the tool when not in use.

    It is also nice and compact and comes with a set of 18 accessories in total. It has variable speed settings. It runs quietly and so is ideal when you live in a built-up area or for trimming your dog’s nails.

    • Great for precision
    • Light built-in
    • Clear displays
    • Compact
    • Light
    • Battery charging time is around 3 and a half hours.

    4. Cordless Dremel 7700-1/15 Rotary Tool Kit – Best Value

    Dremel 7700-1/15

    This Dremel is the best option if you want great value for money. It is a good deal less expensive than our top choices. The company has stripped out some of the less important features but included a range of 15 accessories, making this a very useful kit.

    This option is not as powerful as the others, but it will still perform many of the same tasks. It just might take a little longer. It offers two speeds, so it is a paired down version of the more expensive models in this light.

    The charger takes around three hours to charge and will not last quite as long as some of the other models. This is not as much of an issue as you could always buy a spare charger to use.

    It is compact, doesn’t weight much at all and is ideal for use on the go. There are better Dremel tools out there, but not at the same price.

    • Price is good
    • Plenty of accessories
    • No need to upgrade soon
    • Compact and lightweight
    • Not the fastest or most powerful model
    • Comes with a wrench to change accessories

    5. Dremel 7000-PK

    Dremel 7000-PK

    Okay, we realize that this is an older model, but it really does not make the grade. Save your money and, if need be, pay the extra for one of the models reviewed above.

    Our first issue with this is that it takes AA batteries. You need four of them, and they drain pretty quickly. So, unless you have a charger and backup set, you’re going to have a lot of downtime.

    The second issue is that it is a 6 Volt model. So, it is not nearly as versatile as newer models.

    Our third issue is that it is only a two-speed model. This does not allow for much variety when you need to work at faster speeds.

    And, to add insult to injury, you only get a puny set of five accessories, and it does not include the EZ Nose Twist Cap. You are paying less, for sure, but this is not a tool to delight a DIY enthusiast by any stretch of the imagination.

    • The price is low
    • Drains batteries
    • Very few accessories
    • Hardly any power
    • Difficult to change out accessories

    Buyer’s Guide

    When it comes to a Dremel, the thing to concentrate on is what you will use it for most of the time. Here are some things that you must keep in mind:

    • Does the power output match the kinds of projects that you want to do?
    • Do you need to have variable speed or not?
    • How long will you need to use it for at a time?
    • How quickly do you need it to charge?
    • What accessories you are most likely to use?


    There you have it – a comprehensive list of cordless Dremel reviews. Top honors go to the Dremel 8220. It is a little pricier than some, but it does come with the most comprehensive range of tools of all the models and some pretty useful features.

    The title for the best value for money option goes to the Dremel 7700. While not as powerful as our first choice, it does pack quite a punch on its own and is a great starter set.

    Overall, Dremel tools are excellent for crafters – both amateur and professional. We hope that you have found this review helpful and that you have fun with your new Dremel.
