Which rotary tool is best?

Few tools can match the versatility of a rotary tool. There isn’t much they can’t do. 

If you’re looking for a high-quality option, few manufacturers can compete with Dremel. In fact, their name is so synonymous with rotary tools that many people simply refer to all rotary tools as Dremel tools no matter who made them. Because of this, it should come as no surprise that the Dremel 8220-2/28 12-Volt Max Cordless Rotary Tool Kit stands out as one of the top options for practically any application.

What to know before you buy a rotary tool


Any time you are using power tools, safety should be a top priority. For rotary tools, this means wearing safety glasses to protect your eyes from dust and debris that may go flying. It is also a smart idea to wear hearing protection since rotary tools can be very loud. Depending on the material you are working with, you may also want to wear a mask so you don’t inhale small particles from the air. Some people may also opt to wear gloves to reduce the vibrations transferred to their hands. However, you need to be careful to ensure that whichever gloves you choose don’t hinder your grip on the tool.

Corded vs. cordless rotary tools

Both corded and cordless rotary tools offer some benefits and cons that should be considered before choosing one.

  • Corded rotary tools: With a corded model, you never have to worry about it running out of power in the middle of a job. They also tend to be more powerful than cordless models, though this gap lessens every year as battery technology continues to improve.
  • Cordless rotary tools: Cordless models are more convenient. You won’t ever find yourself in a situation where the cord is getting in the way as you work. You’ll also never have to deal with running extension cables when there isn’t a power source right next to your worksite.

Features to look for in a quality rotary tool


The speed of a rotary tool is denoted in rpm, which stands for revolutions per minute. On nearly every model, you can adjust the speed either using a variable speed slider or dial or by selecting one of a few preset speeds. The wider the range between the fastest and slowest speed, the more versatile a rotary tool will be. Some models have speeds that range from as low as 3,000 rpm to as high as 40,000 rpm.


The power of rotary tools is measured in volts for cordless models and amps for corded models. The higher the number, the more powerful the tool is. Not everyone needs the most powerful rotary tool though, as it depends on your application. If using your tool for arts and crafts or small hobby projects, 1-1.5 amps or at least 4 volts should suffice. If doing heavy-duty construction work or remodeling, it is best to opt for a tool with at least 1.6 amps or 12 volts.


When it comes to the ergonomics of a rotary tool, you should pay attention to a few important aspects. For example, the lighter the tool is, the less fatiguing it will be to use for long periods. Likewise, a grip with a vibration-dampening, nonslip material or one that is nicely contoured will provide a better hold on the tool and more user comfort.

Included attachments

The more attachments a rotary tool comes with, the more versatile it will be right out of the box. Some models may come with just a single attachment, while others may come with as many as 80 or more. These may include attachments for cutting, grinding, sanding, drilling, polishing and engraving. For most rotary tools, you can also buy additional attachments.

How much you can expect to spend on a rotary tool

Rotary tools range from $20-$200, depending on features and included attachments.
