What is an oscillating tool?

An oscillating tool is a handheld power multi-tool used for various home improvement projects. Oscillating tools can be fitted with different blades and attachments for specific uses.

An oscillating tool works by moving the blade or attachment back and forth in a rapid, vibration-like movement. Common uses for an oscillating tool include grout and caulk removal, cutting metal, cutting drywall, sanding, and scraping adhesives.

Oscillating tools are available in both corded and cordless models. The cordless tools run on a lithium-ion battery. The different attachments and blades for oscillating multi-tools are generally available for purchase separately from the tool itself.
