The 10 Best Cordless Rotary Tools
1. Dremel 8220-1/28 Cordless Rotary Tool – Best Overall
Want to cut to the chase and buy the best possible rotary tool that’s out there? For our money, your best bet is the Dremel 8220-1/28 Cordless Rotary Tool.
We were pleasantly surprised by how compact this model is. It lets you reach more places without sacrificing power (the lithium-ion battery helps this reach anywhere from 5,000-30,000 RPM).
It’s also very versatile. Thanks to the quick-change collet lock, you can swap one bit out for another as needed. And this rotary tool comes with dozens of bits (part of the 28 accessories it comes with), giving you plenty of options while you work.
The ergonomic design and 360-degree grip make this tool easy to hold at all times. In fact, our only real gripe is that the batteries do not hold a charge as well as we’d like. You can replace them with better batteries, but it’s still a tad annoying.
2. Avid Power Cordless Rotary Tool – Best Value
Not everybody has a giant budget for their tool collection. And if you’re on a tight budget, you’re probably looking for the best cordless rotary tools for the money. In that case, you should definitely go with the Avid Power Cordless Rotary Tool.
Despite its low price, you get an 8-volt battery that can produce speeds ranging from 5,000 to 25,000 RPM. And it is very versatile, coming with a whopping 60 pieces of accessories to help you get started.
You even get a nice “luxury” touch in the form of 4 front LED lights to help you work in dark places. So, what keeps this from being our number one pick? The battery performance is a little spotty, and it can’t quite produce the power and speed of upper-end models.
3. Bosch Professional Cordless Rotary Tool – Premium Choice
In the world of power tools, the old saying is often true: “You get what you pay for.” Those who want premium tools must be willing to pay premium prices. And the Bosch Gro10.8v-li Professional Cordless Rotary Tool is a great example of this.
It comes with the features you might expect, including a powerful motor that can handle up to 35,000 RPM. And it has a convenient ergonomic design that makes it very easy to hold and to use.
But there are also some nice features you may not be expecting. This includes integrated LED lighting that helps you work in very dark places. And the special electronic cell protection helps keep your battery safe from overheating, overload, and discharges.
At just under 2 pounds, this rotary tool is relatively lightweight. But as we said, it is one of the most expensive tools on our list of reviews!
4. Milwaukee 2460-20 Cordless Rotary Tool
Not every rotary tool is a premium choice or a budget choice. Some are basically in the middle of the road when it comes to price vs. power. And the Milwaukee 2460-20 Cordless Rotary Tool is a great example of this.
It doesn’t come with as many accessories as other models, but it makes up for that with speeds up to 32,000 RPM. And while everybody’s toolkit is a bit different, there is a chance you may already have some of the Milwaukee 12-volt batteries that power this thing.
Despite the lack of initial accessories, the ⅛-inch collet means that this rotary tool can use accessories from pretty much any other brand. And it’s very lightweight (about 1.3 pounds), which means you can use it a long time without getting fatigued.
Honestly, our main gripe is that lack of accessories. That means this tool is less ready to go “out of the box” than some competitors.
5. KeShi WL-45 Cordless Rotary Tool
With three speed settings, the KeShi WL-35 ranges from 5,000 to 15,000 RPM, which is far below average for this type of tool. It has variable vent holes that keep the motor cool and its unique power button design prevents accidental shut-off, which is especially important for engraving work. It’s more of a DIY/homeowner tool than a professional model, but you could, theoretically, use it for anything from sharpening to grinding.
We like the 42 attachments and accessories that include collets, mandrel, drill head, polishing drum, etc., and the storage case to carry them. The tool is suitable for a variety of materials such as plastic, glass, stone, and metal.
However, this is a light-duty rotary tool that’s good for arts and crafts and minor repairs. Professional users will want to steer clear of this model and go for something more powerful like the Dremel 8220-1/28. You get 90 minutes of battery power after 2 hours of charge, but the WL-45 seems to lose a lot of power at the 30-minute mark.
6. EnerTwist Max Cordless Rotary Tool
Need a cordless rotary tool and you don’t want to spend a lot of money? While it’s not the best budget choice, the EnerTwist ET-RT-8 Max Cordless Rotary Tool is a pretty solid option. This price gets you a decent motor that can handle speeds up to 25,000 RPM. And the 8-volt lithium ion battery lasts surprisingly long for such a budget rotary tool.
The ergonomic design makes this tool comfy on the hands, and the built-in LED lighting makes it easy to use in the dark. And we enjoyed the all-in-one nature of this kit, which includes a charger, case, and a 40-piece accessory set.
What keeps this from being our best budget choice, then? The design isn’t very sturdy, and the switches are easily damaged. And some users reported that this tool would unexpectedly power down when they were using it.
7. Kapoo Cordless Rotary Tool
Our reviews have explored a few budget options already. But what if you’re really strapped for cash and need one of the cheapest rotary tools around? That’s where the Kapoo Cordless Rotary Tool comes in.
You can’t beat the price, and we were pleasantly surprised by features like the speedy battery charging (2 hours to charge) and the convenient bundle of 23 rotary accessories. But there are some downsides, including the fact that the motor will only reach speeds of 15,000 RPM.
Additionally, while the tool is comfy to hold, it is prone to damage. And while the 2-hour charging is convenient, some users have experienced problems with the battery right out of the box.
8. TECCPO Cordless Rotary Tool
Cordless rotary tools are great because they can help with so many different projects. And the TECCPO TDRT03P Cordless Rotary Tool is designed to meet a versatile array of needs thanks to the 80 different accessories that are included.
We liked that the 12-volt battery charged in only an hour, and that the motor can bring the tool to speeds of up to 28,000 RPM. Unfortunately, there are a few issues that keep this rotary tool near the bottom of our list.
For example, the overload protection on this tool kept turning it off at the most inconvenient times. And despite its design for versatility, this doesn’t have 100% compatibility with Dremel parts. Finally, despite being able to handle most day-to-day projects, this tool isn’t really designed to handle any truly ambitious projects.
9. TACKLIFE RTD02DC Cordless Rotary Tool
On paper, the TACKLIFE RTD02DC Cordless Rotary Tool is a nice, all in one kit for amateur and veteran handymen alike. Unfortunately, there are more drawbacks than benefits when it comes to this particular model.
We enjoyed the powerful motor that allows this tool to hit 30,000 RPM. And the 43 included accessories are a nice touch, as are the convenient LED indicators.
However, this tool shuts off at even the slightest amount of pressure. The vibration can be distracting, especially during big projects. Finally, it’s a bit bigger and heavier than you might expect, and this negatively impacts its portability and overall usability.
10. GALAX PRO Mini Cordless Rotary Tool
The GALAX PRO USAGP-DC-3R Mini Cordless Rotary Tool comes in at the end of our reviews, and it’s another very cheap option. Unfortunately, this is a rotary tool that proves “you get what you pay for” in a negative sense.
With that being said, there are a few things we liked. The 31 included accessories are nice, and the two-hour USB charging time is good. And at only 0.27 pounds, this tool is easy to lift and use for as long as your project lasts.
However, the relatively weak motor only goes to 15,000 RPM. While it charges quickly enough, the batteries are a bit too weak for plastic and other hard materials. Finally, while the included bits are convenient, they don’t all lock into place very easily, making the entire experience frustrating and inconvenient.
Hopefully, our thorough reviews helped you understand more about the best cordless rotary tools on the market. If you’re still on the fence, though, you may need a little more information. And that’s where our buyer’s guide comes in.
To make the best possibly cordless rotary tool choice, you need to understand more about these different tools and their components. From batteries to bits, our buyer’s guide will help you master this subject and buy the perfect tool for your own needs.
The secret to any good cordless rotary tool is the battery. Once you don’t have to keep the tool plugged in, you can take it with you wherever you go.
However, some batteries are more effective than others. For example, lithium-ion batteries are the best choice when it comes to your different power tools. And that’s because these batteries have a number of advantages compared to traditional batteries.
Lithium ion batteries tend to be lighter in weight than traditional batteries. And that is particularly important for any cordless tool because you don’t want anything too heavy (more on this later).
On top of that, lithium ion batteries typically pack more power than other batteries of the same size. This lets you have your cake and eat it, too: your rotary tool stays lightweight while the battery lasts a long time.
Speaking of energy, lithium-ion batteries tend to charge faster than other batteries. The only thing you need to watch out for is that these batteries tend to overheat a bit quicker than traditional batteries do.
If you plan to use your rotary tool extensively, you may want a model that allows you to swap out different batteries. And if you’re really lucky, you might already have some lithium ion batteries around the house that will work with your cordless rotary tool.
Many of the items we reviewed today are part of cordless rotary tool kits. In addition to the main tool, these kits often include things like cases, chargers, and bits.
When it comes to the number of bits and accessories, more isn’t always better. While it’s nice to get plenty of extra “bonus” accessories, don’t let this convince you to buy a lower-quality tool. For that matter, be sure to examine which bits come with the kit. Better to get 20 bits that you really need versus 80 bits that don’t actually matter!
For first-time buyers, you can basically “work backwards” to figure out which accessories you need. Just take stock of what accessories you already have, what projects you plan to complete, and what you still need to make those projects happen. From there, you can select a kit that has everything you need to get started!
Weight vs Sturdiness
With any tool, there are going to be certain tradeoffs. Sometimes, a strength in one area causes a weakness in another. And that’s definitely the case when it comes to cordless tool weight and durability.
Generally speaking, you want your cordless tools to be lightweight and ergonomic. When they are easy to hold and easy to lift, it makes it correspondingly easy to work for a long time.
However, some cordless tools are light in weight because they are made of weaker, low-quality materials. And if your new tool breaks too quickly, you’ll wish you went for the sturdier option.
Our advice? Check out our reviews for rotary tools that offer a solid intersection of power, durability, and lightweight design.
You may have noticed that the motor speed of cordless rotary tools varies quite a bit. The tools we reviewed mostly had 5,000 RPM as the minimum speed. Maximum speeds ranged from 15,000 RPM all the way to 32,000 RPM.
It’s easy to think “bigger is better.” And it’s true that rotary tools with more speed give you more options. At the same time, not every rotary project is going to need an intense motor.
If you won’t be using the rotary tool very often, or if all your projects are minor, nothing is wrong with sticking to 15,000 RPM. But if you want a motor that can handle tougher jobs, then you need something with the speed to get the job done.
Now that you’ve read our reviews and our buyer’s guide, only one question remains. Which cordless rotary tools are the best in the business?
If you don’t mind spending a bit more money, the Dremel 8220-1/28 Cordless Rotary Tool is the best choice. It offers power and versatility, and the compatibility with other Dremel products is really great.
For those on a budget, the Avid Power Cordless Rotary Tool is our best value choice. It offers many uncompromising features at a surprisingly good price, and it’s clearly the best budget option around.
With any luck, we’ve helped you select the cordless rotary tool that is best for your needs. Now, there’s only one thing left for you to do: pick up the tools and get to work!
