The 5 Best Uses for Rotary Tools

A rotary tool is a versatile power tool that has many different applications. Simply put, a rotary tool is a handheld tool with a fast-spinning motor connected to a spindle. In that spindle, you can attach a tool bit. There are many kinds of tool bits that go in a rotary tool, and they all do a different job. Additionally, the power source is typically electricity or forced air in the case of pneumatics. The small, compact size of the tool decreases worker fatigue and discomfort while using it.

Rotary tools are especially useful for grinding, cutting, and polishing. As such, this all-in-one tool should be in every shop and toolbox. Here are five uses for rotary tools for you to try.


By attaching a grinding bit to the rotary tool, you can now use it to grind almost anything. Use it to create sharp edges on a workpiece or eliminate them. The grinding action of the rotary tool is ideal for deburring finished parts, sharpening knives, and honing other cutting tools.


Rotary tools are great for cutting applications, as they can tackle big and small jobs alike. The right attachment will let you cut anything—straight bits will cut wood, drywall, or any other kind of light material. Further, using diamond or CBN tools will allow you to cut super-dense materials such as steel.


Rotary tools are versatile, small, and comfortable to use, making them perfect for carving and engraving projects. There are carbide bits for wood and metal that let you work on frames, designs, and any other decorative project with fine details and intricate designs. You could even carve a pumpkin with a rotary tool if you want!

Glass Work

A diamond bit in a rotary tool is ideal for cutting and engraving glass. Only use diamond bits on glass because a normal bit will only break it and leave you frustrated and in need of a new piece to work on. While working on glass, it’s important to note that it will heat up. So, wear some gloves and prepare to set it down a few times to let the piece cool.

Polishing and Cleaning

With the right attachment—a sire brush, polishing wheel or polishing point—a rotary tool can polish and clean a lot of things. Simply apply some polishing compound to the buffing bit before turning on the tool, and then clean away. Use it at medium speed so the compound doesn’t fly off the bit.

If you want to further a rotary tool’s versatility, consider adding a diamond abrasive disc attachment. Now it will be able to grind, polish, and deburr natural and synthetic stones, glass, ceramic, and hard metals.
