Cordless Vs Corded Rotary Tools: Which one to choose?

There is a considerable debate between cordless versus corded power tools in the trade industry. Cordless tools are more versatile, while corded devices are much more powerful. Numerous factors impact whether you need a corded or cordless device – from the type of tool to the job you need it for.

A rotary tool uses a fast-spinning motor for grinding, sanding and polishing different materials. You can buy different attachments for the tool for different tasks and materials. For example, you can buy an attachment to cut and engrave glass.

The rotary tool is versatile, hand-held, and lightweight to use. It can be used on all kinds of materials, as long as you have the appropriate attachment and skill required. Just make sure to always wear the appropriate PPE when using this tool and follow safety guidelines.

You can find both corded and cordless rotary tools, and each has its pros and cons.


Cordless rotary tool

Cordless power tools are favoured by many tradespeople because they are easier to manoeuvre. You don’t need to work next to a plug socket, and you can manoeuvre the device easily to engrave and carve materials. You have more freedom and autonomy over the tool, making it perfect for more intricate work. It’s useful on construction sites where there are limited power supplies. You can also use a cordless tool to do quick touch-ups on projects without needing to find an extension cord. Plug sockets are like gold dust on construction sites.

However, there are disadvantages to cordless tools. The main disadvantage of cordless tools is that they need to be charged. You will have to pause your work while the device charges, slowing your progress on the job. There is also less power and speed with cordless devices as most use a battery voltage of 4V or less. Cordless tools are better suited to lighter jobs that don’t require long periods of high-power work.

Corded rotary tool


The more traditional corded rotary tool is much more powerful. It can work for as long as you and is not dependent on a battery. For some materials, like glass and steel, corded tools make a noticeable difference to the work. However, there is no difference in the work produced by a corded or cordless tool with other materials.

Corded tools can be more challenging to manoeuvre on-site, and the cord can get in your way. If you are doing intricate work on a material, the cord may hinder your flexibility and make it difficult to get into the finer details. The cord can also impact your grip on the tool.

Both corded and cordless tools have their advantages and disadvantages. When choosing the best rotary tool for you, consider your work environment and the type of projects you need the device for.
