Report Ranks Best Oscillating Multi-Tools for 2026

- The oscillating multi-tool was originally invented in 1967 by the German company Fein not for construction, but as a medical device to safely cut and remove plaster casts without harming the patient's skin. - Unlike rotary or reciprocating saws, the tool's head moves back and forth in a very small arc, typically just a few degrees, at speeds up to 20,000 oscillations per minute or more. This motion provides exceptional control for precise tasks like plunge cuts and reduces the risk of kickback. - For decades, Fein was the primary manufacturer until its patent for the oscillating mechanism expired around 2009, which then allowed other major tool brands to develop and release their own versions. - Modern advancements in the tool's design include the integration of more efficient and durable brushless motors and significant improvements in cordless battery technology, allowing for power and runtime comparable to corded models. - A key innovation in accessory attachment is the Starlock interface, co-developed by Fein and Bosch, which allows for faster, tool-free blade changes. - The tool is frequently used for trimming door jambs and baseboards to install new flooring, a task difficult for other saws. It can also remove grout with more precision and less dust than an angle grinder. - Beyond cutting, various attachments enable an oscillating tool to function as a detail sander for corners, a scraper for removing paint or adhesives, and a grinder.
