Oscillating Multi-Tool
Affiliate link — we may earn a commissionAn oscillating multi-tool vibrates a blade or pad in a tight arc (about 3 degrees) at 10,000 to 20,000 oscillations per minute. It doesn't spin. That oscillation lets it cut, sand, scrape, and grind in places where spinning tools can't reach. Flush-cut blades trim door jambs, baseboards, and dowels flat to a surface. Plunge-cut blades cut openings in drywall and subfloor. Sanding pads reach into corners that a random-orbit sander can't touch. The tool does many things adequately but none of them as fast as the dedicated tool for that job. It's the gap-filler, not the first tool you reach for.
Why It Matters
Every remodeling project has at least one cut that no other tool can make cleanly. Trimming a door casing to slide flooring underneath. Cutting a nail in a tight spot. Scraping adhesive off a subfloor. The oscillating tool handles all of these. Buy it for the jobs your other tools can't do, not as a replacement for any of them.
