What should I look for in a rotary tool?

A rotary tool is a versatile and handy device that can perform a variety of tasks, such as cutting, sanding, grinding, polishing, carving, engraving, and more. It can be used for DIY projects, crafts, hobbies, repairs, and renovations. But with so many options available on the market, how do you choose the best rotary tool for your needs?

The main factors to consider when buying a rotary tool

The main factors to consider when buying a rotary tool are power, speed, accessories, corded or cordless, and ergonomics. These factors will determine the performance, functionality, convenience, and comfort of your rotary tool.


Power is measured in volts for cordless rotary tools and in amps for corded ones. The higher the power, the more torque and speed the tool can deliver. A powerful rotary tool can handle tougher materials and larger projects, but it may also be heavier, louder, and more expensive. A less powerful rotary tool may be more suitable for lighter tasks and finer details, but it may struggle with harder materials and longer run times. You should choose a rotary tool that matches the power level of your intended applications.


Speed is measured in revolutions per minute (RPM) and indicates how fast the tool can spin the accessory. The higher the speed, the faster and smoother the cutting, grinding, or polishing action. A variable speed rotary tool allows you to adjust the speed according to the material and the accessory you are using. A fixed speed rotary tool may be cheaper and simpler, but it may not offer the same versatility and precision. You should look for a rotary tool that has a wide range of speed settings and a convenient speed control.

Accessories are the attachments that you can use with your rotary tool to perform different tasks. They include bits, blades, discs, wheels, brushes, mandrels, collets, and more. The more accessories you have, the more functions you can perform with your rotary tool. You should look for a rotary tool that comes with a variety of accessories that suit your needs and preferences. You should also check the compatibility and availability of the accessories, as some may be specific to certain brands or models.

Corded or cordless

A corded rotary tool plugs into an electrical outlet and provides consistent power and speed. It is ideal for heavy-duty and continuous work, as it does not run out of battery. However, it may limit your mobility and reach, as you have to deal with the cord and the proximity to the power source. A cordless rotary tool runs on a rechargeable battery and offers more portability and flexibility. It is ideal for outdoor and remote work, as you do not need an outlet. However, it may have less power and speed than a corded one, and it may require frequent charging and battery replacement.


Ergonomics refers to the design and comfort of the rotary tool. You should look for a rotary tool that has a comfortable grip, a lightweight body, a balanced weight distribution, and a low vibration and noise level. These features will reduce fatigue and strain on your hand and wrist, and enhance your control and accuracy. You should also look for a rotary tool that has a user-friendly interface, a clear visibility, and a convenient storage and carrying case.
