This tool is a dream for contractors and a nightmare for their accountants. The MultiMaster is a well-built, German-engineered workhorse, but it’s the most expensive tool of the bunch and has the most expensive accessories. It cut oak and maple, sanded wood, scraped caulk and glazing, and removed grout for hours without excessive heat or noise. The tool has a soft-start motor, and its 16-ft. cord is supple enough never to be a bother. Similar to the Rockwell, Fein includes vacuum collection in the form of a modified plastic hose that clips to the bottom of the tool. But the Fein port is larger, which allows it to draw more suction. Also like the SoniCrafter, the MultiMaster feels sort of like holding the fat end of a baseball bat. Clearly, two decades’ worth of research and development have paid off because unlike the other tools, which rely on a hex wrench and bolt to hold the accessories in place, Fein offers a quick-change system. By lifting a lever on the top of the tool, a pin is released on the bottom, allowing accessories to be inserted and removed. The quick-release system starts with the FMM 250Q Basic kit at $270, and if you’ve ever fumbled with a hex wrench and a small bolt, it’s easily worth the extra $60 over the $210 FMM 250 Start kit. Fein also makes a cordless tool (MSx 315) but plans to discontinue it in the near future. The best overall is the FMM 250Q Top, which includes the quick-change setup, a vacuum attachment, an excellent case, and accessories.
