Cordless rotary tools can be a great option for certain tasks, but it's important to consider their limitations. As an expert brewer and sommelier, I have had the opportunity to use both corded and cordless rotary tools in my professional work.
One of the main advantages of cordless rotary tools is their portability. They allow you to work in areas where access to a power outlet may be limited or unavailable. This can be particularly useful if you're working on a project outside or in a remote location. I have found this especially beneficial when I have needed to do some quick repairs or modifications at outdoor events or in tight spaces where a corded tool would be impractical.
Another advantage of cordless rotary tools is their ease of use. Without the restriction of a cord, you have more freedom of movement and can easily maneuver the tool in different positions. This can be particularly useful when working on intricate or detailed projects, such as carving or engraving. I have used cordless rotary tools to create intricate designs on wooden barrels for my brewing experiments, and the freedom of movement allowed me to achieve precise and detailed results.
However, it's important to note that cordless rotary tools are limited by their battery life. Depending on the model and the tasks you're performing, the battery may not last as long as you need it to. This can be frustrating if you're in the middle of a project and have to stop to recharge the battery. To overcome this limitation, many cordless rotary tools come with additional batteries or offer the option to purchase them separately. I have found that having spare batteries on hand is essential to ensure uninterrupted work, especially when I have multiple projects lined up.
In terms of performance, cordless rotary tools have come a long way in recent years. The Dremel 8220, for example, is a high performer that can rival corded models. It offers variable speeds and a range of attachments to tackle different tasks. However, it's important to manage your expectations. While cordless rotary tools can handle most loads, they may not have the same power and endurance as their corded counterparts. For heavy-duty tasks or prolonged use, a corded rotary tool may still be the better option.
Cordless rotary tools can be a valuable addition to your toolkit, providing portability and ease of use. They are especially useful for tasks where access to a power outlet is limited. However, their battery life can be a limiting factor, so it's important to have spare batteries on hand. The Dremel 8220 is a good option that offers high performance and value in kit form. Ultimately, the choice between a cordless and corded rotary tool depends on your specific needs and the nature of your projects.
