Here's a list of the top cordless Dremels we found:

  • High performance motor
  • 12 volts of power
  • Easy twist nose cap
  • 5,000-33,000 RPM speed range
  • One-hour charge


  • Stunning versatility
  • Easy accessory change
  • Rapid charging
  • High-quality materials


  • Large size
  • Some users report battery issues


In terms of overall performance, rotary tools don’t get better than this. The speed range that this Dremel has means that it can perform a wide variety of different tasks. It has a great range of power allowing it to cut through metal and many other hard materials.

One brilliant feature of this Dremel is the ‘EZ twist’ nose cap it has. This means that accessory changes will be rapid. The battery also charges very quickly, therefore you are going to have minimal downtime between jobs. Some users have been unhappy with the battery life but the vast majority of customers have no complaints.

2. Cordless Dremel 7700 MultiPro Tool Kit

  • 10,000 to 20,000 RPM speed range
  • Ni-Cd battery
  • 7.2 volts
  • Removable battery
  • 3-hour charging


  • Lightweight
  • Perfect for small projects
  • Great accessories
  • Compact size


  • Only two speeds
  • Inconsistent power output


This doesn’t quite have the same level of power as the previous model but it’s great for a wide range of tasks. The size and weight of the Dremel makes it very easy to hold and to get into tight spaces where other rotary tools might not be able to reach.

The removable battery that it has makes for easy charging with the option to have a spare if you wanted a non-stop cordless tool. For those looking for an everyday rotary tool, this is ideal. It comes with Dremel’s notorious quality and has a great level of durability.

3. Dremel 7300 MiniMite 4.8-Volt Cordless Two-Speed Rotary Tool

  • 4.8 volts
  • 6,500 to 13,000 RPM speed
  • Compact size
  • Ni-Cd battery
  • Durable plastic housing


  • Great for intricate tasks
  • Highly portable
  • Highly rated
  • Durable build quality


  • Lacks power
  • Longer charging time


For those looking for a smaller rotary tool for more intricate tasks, this is perfect. It is still able to complete sanding, grinding and cleaning tasks but the power is limited to 13,000 RPM. It still has good versatility and the ratings prove the level of quality it has.

The 7300 is the most compact rotary tool on this list. What it may lack in power it more than makes up for in usability. It weighs just 1.1 pounds and you will be able to use it for a long time without fatigue. If you’re not looking to complete heavy-duty tasks, this is an excellent rotary tool.

4. Dremel 8050 Cordless

  • Narrow design
  • Docking station
  • LED lighting
  • 8 Volts of power
  • 5,000 to 28,000 RPM speed range


  • Great speed range
  • Easy to handle
  • Light for easy viewing
  • Can continuously charge


  • Not for heavy torque
  • Some users have charging issues


For a rotary tool that has a very slim design, this Dremel has a great speed range. That allows you to complete a wide range of jobs but it can struggle to handle tasks that require a high level of torque, such as cutting. For most jobs, however, it’s perfect.

The LED lighting that it has can really help as it casts a light on the end of the tool which is great for intricate work. The charging dock featured allows you to easily put the tool on charge when you need to place your Dremel down and that allows you to work more continuously.

5. Dremel 8100 8-Volt Max Rotary Tool

  • 5,000 to 30,000 RPM speed range
  • Lithium-ion battery
  • Easy twist nose cap
  • 8 Volts of power
  • Comfort grip


  • Quick accessory change
  • Long battery life
  • Easy to hold
  • Variable speed control


  • Lacks power for its size
  • Low build quality


This is Dremel’s second largest cordless rotary tool in their current range and with that comes a great range of RPM at variable speed. The ‘EZ twist’ cap that it has allows for a very quick accessory change without having to use a wrench.

For its size, though, it doesn’t have a great level of torque and it can be difficult to hold for some. If you need power it would make sense to go for the 8220 model and if you needed a more portable Dremel, the 8050 model would be perfect. This is still a good product but not as good as the 8220, which has the same features but with more power and better quality.

Buying Guide


The revolutions per minute are perhaps the most important aspect to consider. If you are a professional who has cutting needs then a high RPM of over 25,000 would be ideal. For more intricate jobs, a lower RPM can be better.

The 8220, 8100 and 8050 models all offer a variable speed which can be very useful. The voltage is also important as that will work hand in hand with the RPM. The 12V of the 8220 allows for a high level of torque and works perfectly for the most difficult of jobs.


The size of these models ranges quite a lot. As you can imagine, this generally changes with the increased power a product has. If you have any issues such as arthritis then a smaller model is most likely going to be ideal.

The larger models can be difficult to handle for some but they are designed quite well to enable you to have a good grip. The 8050 model is a great compromise in terms of size as it has a good level of power but is very easy to hold.

Charging time

When it comes to cordless products, charging time and battery life can be real issues. Dremel’s are high quality in that respect as they tend to charge quickly without dying too soon. For the best battery life, you need to look for a Lithium-ion battery.

Dremel has this on their three largest models before switching to Ni-Cd batteries for their smaller models. This is because they don’t require the same level of power but it can mean longer charging times. Again, this is about balancing your needs and requirements.


Dremel are great for giving you a great number of accessories with your rotary tool. It’s important, however, to check that they are going to be right for your needs or if you need to look for extra accessories. This will entirely depend on the type of job you plan on doing.

For example, the smaller products that they have in their range tend to come with more carving and engraving accessories. The larger models will have more cutting and grinding accessories. You simply need to check that the accessories are covering your needs.

Wrapping it up

There are many reasons to use a rotary tool. From trimming dog’s nails, polishing piano pedals to cutting metal, you need to get the right product for the job. Thankfully Dremel have a great range of tool to help you do just that.

In terms of overall usability and versatility, it’s hard to look past the Dremel 8220 as being the best rotary tool for you. The large variable speed it has will allow you to easily complete any task. It’s not just that, however, as it’s also very easy to use and has a great battery life. It’s a great tool and one you’ll be very happy with.
