For most shops the CRAFTSMAN CMEW401 is the oscillating tool to buy: a 3-amp corded multi-tool with a variable-speed dial and tool-free blade changes, for around the price of a bare cordless head. If you already own M12 batteries, Milwaukee’s brushless 2526-20 is the better tool.

An oscillating multi-tool is the thing you reach for when no other tool fits. It cuts flush to a surface, plunges into the middle of a panel without a pilot hole, trims a door jamb in place, and scrapes old adhesive off a floor. Nothing else does that set of jobs, which is why a cheap one still beats not owning one.
The tools below are the ones currently buyable. Three of the five this guide used to recommend — the Dremel MM40-05, the Rockwell Sonicrafter F80 and the Porter-Cable PCE606K — are gone or sellerless, and the corded DEWALT it recommended now only shows up as refurbished stock at more than the price of a new CRAFTSMAN. Blade compatibility is the thing that changed most in the meantime, and it matters more than any spec on the box.

Three amps, corded, variable-speed dial, and a tool-free universal accessory mount. That last item is the one to care about: it accepts the OIS-pattern blades that nearly every brand now sells, so you are buying into a blade market rather than a proprietary one. Changing a blade needs no hex key, which sounds minor until you are up a ladder.
Corded is the right default for a tool like this. An oscillating tool does its work in bursts of thirty seconds to two minutes, and it does that work while buried in material, drawing current the whole time. A cord means it never fades mid-cut and you never wonder what the battery is at.
It is also VERSATRACK compatible, which only matters if you have already bought into CRAFTSMAN’s wall system.

Sold as a bare tool, brushless, on the M12 platform. If there are already M12 packs in your shop this is the best oscillating tool on the page and it costs less than the corded CRAFTSMAN.
A brushless motor matters here more than in most tools, because the oscillating head stalls constantly and a brushless controller recovers from a stall without cooking itself. The M12 size is the other half of the argument: this is a small tool, and a small tool is what you want when the cut is behind a toilet or inside a cabinet carcass.
If you do not own M12 batteries, a pack and charger roughly doubles the cost, and at that point the DEWALT kit below is the better buy.

DEWALT DCS356D1 — Best Way Into Cordless From Scratch
The 20V MAX XR oscillating tool with a battery and charger in the box. Three-speed selector, brushless, and it joins the largest cordless platform most people are likely to end up on anyway.
Worth checking before you buy: this listing has been filling from a third-party seller rather than DEWALT or Amazon, though it ships through Amazon’s own fulfilment. The price has been sitting at about market, not above it, which is the useful distinction — a lone reseller charging a premium is the pattern that tends to vanish a few months later.

Genesis GMT15A — Cheapest Tool That Still Counts
A 1.6-amp corded tool with a 19-piece accessory kit and a storage box, and the only recommendation on this page that survived from the previous version. It has been on sale continuously for years, which for a budget tool is the only durability signal that means anything.
At 1.6 amps it is half the motor of the CRAFTSMAN and it will bog down in hardwood or thick nail-embedded stock. For trimming shims, cutting drywall, sanding into a corner, or finding out whether you want one of these at all, it is plenty.
The accessories are hook-and-loop rather than the universal mount, so budget for a pack of OIS blades and an adapter if you get serious.

What Actually Matters
The blade mount, before anything else
Most tools now take the universal OIS star-shaped mount, and blades for it are cheap and everywhere. Older and cheaper tools use proprietary or hook-and-loop fittings, and the tool’s purchase price stops mattering once you have bought three sets of blades for it. Check the mount first. A 3-amp motor with a dead-end blade pattern is a worse buy than a 1.6-amp one that takes anything.
Oscillation angle and speed
Speed is quoted in oscillations per minute and the useful range runs from roughly 10,000 to 20,000. Higher is faster in wood and worse in metal and plastic, where heat is the enemy — which is the whole reason a variable-speed dial earns its place. The oscillation angle matters too: a wider angle cuts faster, a narrower one is easier to control on a finish surface.
Corded or cordless, honestly
Cordless wins on access and loses on sustained load. If the tool lives on a bench, buy corded and spend the difference on blades. If the work is overhead, in a crawl space, or on a ladder, the cord is the problem and cordless is worth the premium. Our cordless oscillating tool guide goes deeper on the battery platforms.
What it will not do
An oscillating tool is a finesse tool, not a demolition tool. It cuts slowly compared with a circular saw or a reciprocating saw, it wanders if you lean on it, and it will burn a blade in seconds in hardened steel. It will cut metal with the right blade and a slow speed, but nails and thin sheet are the realistic limit.
The Blade Decides What the Tool Can Do
Buying the right blade is a bigger lever on results than moving up two tool price brackets, and the four types are not interchangeable.
High-carbon steel (HCS) blades are the cheap ones that come in the box. They cut softwood, drywall and plastic, and they dull the instant they touch a nail. Treat them as disposable and keep a stack.
Bimetal blades weld a hardened cutting edge onto a flexible spring-steel body, which is why they survive hitting a fastener. If you are cutting anything that has ever been nailed — old trim, subfloor, framing in a remodel — this is the only sensible default. One bimetal blade outlasts a handful of HCS ones in that work.
Carbide blades have brazed teeth or a grit edge and go through hardened screws, cement board, thinset and fibreglass. They cost several times a bimetal blade and they are the only thing that will do those jobs at all, so buy one when you need it rather than keeping a set.
Diamond grit segments are for tile, grout and masonry, and they grind rather than cut. Run them slow and wet where you can.
Then there are the non-cutting accessories, which is where the “multi” in multi-tool is earned: triangular hook-and-loop sanding pads for corners a random-orbit sander cannot reach, flexible scrapers for adhesive and old caulk, and rigid chisel blades for knocking out hardened mortar. The sanding pad alone justifies owning one of these if you build furniture.
The Jobs It Is Genuinely Best At
Undercutting door jambs for flooring. Lay a scrap of the new flooring on the subfloor as a height gauge, rest the blade flat on it, and cut the jamb and casing off at exactly the right height. No other tool cuts flush to a floor like that, and the alternative is removing the casing and reinstalling it.
Plunge-cutting a patch. Mark the opening, tip the blade in at an angle, and walk it down into the drywall or panel without a pilot hole and without over-cutting the corners. A jigsaw needs a starter hole and a drywall saw wanders.
Cutting a nail you cannot reach. A bimetal blade slid into the gap behind trim will cut finish nails flush while the trim stays where it is. This is the job that sells people on the tool.
Removing grout and old caulk. A grout blade clears a joint faster than a manual saw and with far less chance of chipping the tile edge, and a flexible scraper lifts silicone in strips.
Sanding into a corner. The triangular pad gets right into the intersection of two surfaces. It is slow for large areas and unbeatable for the last inch.
What all of these have in common is access. If a tool with a spinning blade could reach the cut, it would be faster. The oscillating tool’s value is that it works where nothing else fits.
Questions People Actually Ask
Do expensive blades matter more than an expensive tool?
Yes, and it is not close. A bimetal or carbide blade in a $32 tool will out-cut a worn carbon-steel blade in a $200 one. Blades are the consumable that determines what the tool can do, so buy the tool that takes the cheapest good blades.
Can an oscillating blade be sharpened?
Not usefully. The teeth are small, hardened and set, and a few passes with a file ruins the geometry. They are consumables; replace them.
Is a rotary tool the same thing?
No. A rotary tool spins a small bit at very high speed for grinding, carving and polishing. An oscillating tool vibrates a flat blade through a narrow arc for cutting and sanding flush to a surface. We compare them in detail in our oscillating tool versus rotary tool guide.
Verdict
Buy the CRAFTSMAN CMEW401 unless you have a reason not to. Already on M12? The Milwaukee 2526-20, every time. Starting a cordless collection? The DEWALT kit. Want to spend as little as possible and still own a real one? The Genesis, and put the savings into a decent set of bimetal blades — which will do more for your results than any upgrade on this page.
