Stan, no, I have a cordless “Dremel” also and keep it in the coach because of its small size and cordless convenience. At home I have a full-featured corded one with more versatility.
But they’re a whole different animal than what we are discussing. The MultiMax is an oscillating tool, not a rotary one. The bits and blades are totally separate in operational principle. As others here agree, you won’t easily beat an oscillating multi tool for removing the old sealant/caulk.
It was great last fall when I had to finesse-cut out sections at the bottom of home doorframe that had rotted out. My MultiMax was super for cutting back at odd angles to clean wood and to proper depths. And it did it quickly. It left exactly what I wanted for applying epoxy fill, and the doorframe wood looks like one straight piece again. I’d hate to think how long it would’ve taken to do without the MultiMax.
There are many more brands available, like Delta, Makita, Bosch, you name it. Check Harbor Freight like David did if you’re cutting costs as well as sealant. But I can endorse the Dremel quality and such things as it’s blade lock/release I really like. But yes, Keith, there are cordless ones now:

If I was considering a cordless oscillating multi tool, Makita would top my list to shop pricing for.
