Rotary tools are a practical choice for small projects like cutting in tight spaces, engraving, carving, and grout removal. They are great for the small-scale application because of the efficient power and convenient size. The rotary tools are either cordless of electric models. This tool is quite similar to the oscillating multi-tools, but has a fixed spinning motion. Also, it operates at a high-speed, so the cutting action isn’t always the smoothest.
Here is an overview of the different types of rotary tools:
The cordless rotary tools are the most portable and give greater freedom in use. They can operate anywhere on a job-site provided the battery pack is charged. It is great to quickly finish jobs that are out of reach of a convenient power source. However, the run-time of the cordless unit is limited. It is only possible to work while the battery holds enough charge go give full power and performance. A typical full charge is in the region of 60 to 90 minutes, and a complete charge takes about 3 hours. Also, the cordless unit will be slightly heavier because it has to accept the extra weight of the lithium battery.
The electric rotary tools completely remove the concern of running out of power at an awkward moment. With a suitable power source in place, this tool can run as long as needed. The power cord is usually in the region of 6-feet so this gives a decent amount of freedom to move around. They are a practical choice for the lengthier or heavy-duty projects because of the ability to rely on constant power. Also, with no battery in place, the overall weight of the tool is lighter. This lowers the risk of fatigue for the user. A negative of this type of tool is having limited access. Projects can only be completed within the length of the power cord. An extension cord can help to widen the workable area, but this isn’t always a convenient option.
Before you buy
There are several factors to consider when buying the rotary tools. A major point is the type of work to complete. The professional in need of a reliable tool for day-to-day jobs will need something more powerful than want a hobbyist needs. The electric unit is preferred for those that demand constant power. A portable one isn’t practical for the long or heavy-duty jobs because the battery will need to be constantly recharged. But, for those working on a light home project, the cordless unit can fit the needs.
