An oscillating multi-tool cuts flush, plunges into drywall, scrapes caulk, and trims door jambs. We used each one on undercutting jambs, cutting out grout, and removing old caulk.

The company that invented the category still makes the best one. Lowest vibration of anything tested and it never bogged in grout.
Cordless with enough torque to undercut jambs without stalling. The best pick if you already own M18 batteries.
Comes with a decent accessory kit and the universal blade adapter fits almost anything you already own.
For a couple of caulk-removal jobs a year, this is enough tool. Do not expect it to survive daily grout work.
The Starlock blade interface transfers power better than any other mount we used, which shows when grinding grout.
Each tool ran the same three tasks with identical blades where possible, and we timed how long it took to undercut a door jamb for flooring.
