Oscillating multi-tools are not optional when you're cutting into existing walls. Drywallers need them for HVAC boots, light housings, pipe access, and chasing conduit near joists. Most oscillating tools handle general demo. These are the ones that actually work in tight, angled spots common to drywall retrofits.
The big brands all claim their oscillating tools are the best. We took five models into real retrofit jobs. We tracked which ones lasted through a month of daily work and which failed on the second day.

The DeWalt DCS356B is the workhorse we take to every retrofit. The metal blade clamp doesn't loosen under load like cheaper plastic ones. We cut through steel studs without blade play. The motor pushes through stacked framing where other tools bog down.
It's not light. You feel it after a full day of overhead cuts. But it finishes the job without quitting. We've had the same tool for three years on a high-volume drywall crew.

Bosch went all-in on power with the CM154. It's corded, so you're tied to an outlet or generator, but that gives it more sustained cutting ability than any 20V model. Use this when you're doing large-scale demo or cutting through thick blocking.
It cuts deeper than any other oscillating tool we tested. We use it for cutting large access holes in shear walls and for removing full sections of blocking where a recip saw would be too aggressive.
We run it off a 30A breaker with a 12/3 extension cord. On jobs with open walls, it's unbeatable. For tight attic or crawlspace work, go cordless.

When you're cutting through fireblocking between joists in an attic or need to trim drywall around a new vent boot in a finished ceiling, space is limited. The Makita KO187 is the most compact top-tier oscillating tool we've tested.
Use the variable speed to start slow when cutting into existing drywall. Bumping it up too fast can tear the paper backing. The LED helps when working in dark walls where a flashlight doesn't fit.
It doesn't have the raw power of the DeWalt, so avoid using it on stacked lumber or steel. But for precise, tight-access work, it's unmatched.

Metabo HPT (formerly Hitachi) offers strong performance at a lower price than DeWalt or Bosch. Its 36V system delivers torque that rivals 20V pro tools but in a slightly heavier package.
Most drywallers don't need this much power. But if you're doing heavy demo work or working with old, dense framing, the extra muscle helps. The battery life lasts through a full day of moderate use.
It's bulkier than the Makita or DeWalt, so it doesn't fit in tight spaces as well. But for general wall cutting where reach isn't an issue, it's a solid choice.
Most oscillating tool reviews come from general remodelers or DIYers. They don't cut into walls every day. These are the specs that matter when drywall is your trade.
A secure blade lock is critical. The metal cam clamps on DeWalt and Metabo HPT hold better than Bosch's tool-less system or Makita's lever. Loose blades cause inaccurate cuts and increase vibration.
You need at least 1.25 inches of reach to cut through standard 2x4 studs. Deeper is better for cutting through stacked lumber. The Bosch CM154 leads here with 1.75 inches.
For most drywallers, cordless is best. You're working in unfinished spaces without power. Corded tools like the Bosch CM154 are only viable on open framing jobs with available circuits.
Overhead work lasts all day. A heavy tool in your hand leads to fatigue. DeWalt and Makita strike the best balance between power and weight. The Metabo HPT is noticeably heavier.
Higher OPM cuts faster but increases tear-out on drywall. A variable speed dial lets you reduce speed during finish cuts. Makita and DeWalt offer this. Bosch and Metabo HPT are full power only.
Test any oscillating tool on these common drywall scenarios before buying.
You're cutting a perfect circle through drywall to fit a can light. Paper tear-out ruins the look. Use a carbide-grit blade and a slow start speed. DeWalt and Makita excel here.
Cutting drywall to match a metal boot requires precision. A metal blade works best. You need depth to cut through the drywall and into the stud to create a clean edge. All tools tested can handle this.
When running wire in finished walls, you cut a narrow channel along a stud. This exposes insulation and framing dust. A wood blade works best. The cut needs to be clean to patch easily. Bosch CM154 handles this well with its consistent power.
No oscillating tool performs without the right blade. Carry these in your van.
Never run a tool without a blade. The tool tip will chew up when hitting stud. Change blades at the first sign of dullness.
Pair your oscillating tool with the right gear.
