Choosing Rotary Tools

Rotary tools are extremely versatile handheld tools, well-suited to many do-it-yourself and professional applications. Since these tools are so versatile, choosing the right one for your project can be a little confusing. Use our guide to sort it all out.


Rotary tools can be divided into two types - Cut Out Tools and Basic Rotary Tools. The biggest difference between the two is the size of their motors. Cut out tools usually have larger motors.


Cut out tools are available in both cordless and corded versions. Cordless tools can be more convenient. The corded versions are slightly more powerful than cordless.

Corded cut out tools have motors ranging from four to five amps. The powerful motors allow the tool to quickly cut through most building materials without bogging down.

Corded rotary tools have motors around one amp. Rotary tools don’t cut as quickly as cut out tools, but the smaller motors give the user greater control.
