An oscillating multi-tool is only as good as the blade clamped in it, and blades are what you keep buying. Trimming a door casing, cutting a nail behind a baseboard and lifting old caulk are three jobs for three different blades. If you want one box that handles most household work, buy the PECHAM 24-piece set: seven blade types for wood, plastic and light metal, and 19,843 owner ratings at 4.5 stars. If you would sooner own three blades from a tool brand than two dozen generic ones, the DEWALT DWA4215 set is rated higher, at 4.7 stars.
This guide covers blades and scrapers, not the tools. We read through the oscillating blade sets in our tools catalog and chose five that do different jobs. Nothing here was bench-tested by us. The comparison rests on what each listing states and on owner ratings and reviews at the time of writing. Prices change daily, so every button opens the live Amazon page.
How we picked
- One set per job: a mixed kit, a brand-name starter set, fast wood blades, bi-metal blades for nails and soft metal, and scrapers.
- Fit stated in the listing. Each pick names the tool brands or mounts it fits, and most also say what it does not fit. We repeat those limits below.
- Owner ratings of 4.5 stars or higher, with review counts from 695 to almost 20,000.
The picks
This is the box to keep next to the tool. PECHAM packs 24 quick-release blades in seven types, with standard, Japanese and precision tooth patterns, made from high carbon steel and stainless steel with a black corrosion-resistant coating. The listing names Fein Multimaster, Ryobi, Milwaukee, Hitachi and Black and Decker among the tools it fits. Owners are realistic about what they bought: one 4-star reviewer says the blades dull quickly but can be touched up with a file, and a 3-star review says a tough job may use up two or three. At this price per blade, that is the deal.
- 19,843 owner ratings at 4.5 stars, the most reviewed oscillating blade set in our catalog
- Seven blade types cover plunge cuts, flush cuts and trimming
- Inch and centimeter depth marks printed on the blades
- Two C-clip adapters included for Rockwell, Worx, Fein Supercut and Dremel MM40/MM45
- Owners say the blades dull quickly in hard use
- Not for Fein Starlock, Bosch MX30 or Bosch quick-release tools
- Mostly carbon steel, so keep them away from screws and hardened nails
Three blades do not sound like much, but they are the three most people reach for. The set has a DWA4203 blade for wood with nails, a DWA4210 semicircle blade for long straight cuts and flush work, and a DWA4217 scraper. DEWALT describes the mount as universal fitment for all major oscillating tool brands, with no adapter. Owners rate the set 4.7 stars over 1,751 reviews and describe it as exactly what they expected from the brand. For a multi-tool that comes out a few times a year, that is enough.
- 4.7 stars from 1,751 owners, the highest rating of the five
- Universal fitment for all major brands with no adapter, per DEWALT
- Three different tools: a plunge blade, a semicircle blade and a scraper
- A known tool brand behind the blades
- Only three pieces
- No price in our catalog data at the time of writing, so check the live listing
- One owner advises keeping them away from nails and screws
LEILUO 7Pcs Oscillating Tool Blades Wood, Japanese Teeth Multitool Blades
For door jambs, baseboards, flooring undercuts and PVC pipe, a Japanese-tooth blade is the fast option. LEILUO’s seven-piece set runs from 40 mm to 70 mm in cutting depth, so the longer blades can plunge through thick lumber in one pass. The material is high carbon steel, which means wood and plastic only. Owners rate it 4.5 stars across 3,863 reviews. The critical reviews mention a blade snapping at the base and the Dremel adapter bending, so treat these as inexpensive consumables, not heirlooms.
- Priced under ten dollars in our catalog data at the time of writing
- Japanese-tooth pattern made for fast, clean cuts in wood and PVC
- Long 55 mm and 70 mm blades reach through thick boards
- 3,863 owner ratings at 4.5 stars
- Wood and plastic only; carbon steel teeth will not survive nails
- A 3-star owner found a blade too thin and broke it at the base
- Not compatible with Starlock tools
AMZWEI 10PCS Bi-Metal Oscillating Tool Blades for Metal Cutting
Renovation work means hidden nails, and a carbon steel wood blade loses its teeth on the first one. Bi-metal blades are the fix. AMZWEI lists these ten for hard wood, soft metal, plasterboard and plastic, and is candid that they are not for bolts or screws. Owner reports are mixed in a useful way: one cut through nails without trouble, a reviewer who does carpentry says they hold up well if you stay away from nails, and one could not get through aluminum at all. Expect a nail-tolerant wood blade, not a metal saw.
- Bi-metal teeth hold up to nails better than carbon steel
- Curved edge makes it easier to start a plunge cut on a line
- Listing names Dewalt, Bosch, Fein, Milwaukee and Ryobi
- 4.5 stars from 695 owners; 30 and 50 packs also listed
- The listing itself says not suitable for bolts or screws
- One owner could not cut aluminum with them
- Owners report they wear fairly quickly
Scraping is the job people forget a multi-tool can do. This set has four rigid 2-inch scraper blades and four tapered 4-inch knife blades in stainless steel, for lifting caulk, adhesive, paint, carpet glue and vinyl flooring. One owner used them on a DeWalt to take up carpet glue; several others bought them to slice cardboard for recycling. The listing is unusually specific about fit, with separate lists of tools the blades fit and do not fit, and an adapter for some Bosch and Dremel models. Read both lists against your model number, because a 2-star review from a Bosch owner says the blade would not hold.
- 4.6 stars from 1,904 owners
- Two blade shapes: a rigid scraper and a tapered knife blade
- Owners use them for carpet glue and for cutting up cardboard
- Listing prints a long fit list and a not-fit list
- A Bosch owner reports the blade would not stay clamped
- Owners say the knife blades dull fairly quickly
- The fit and not-fit lists overlap on some brands, so check your exact model

Will it fit? Universal mounts and Starlock
Most oscillating blades, including all five sets here, use an open-backed “universal” or quick-release mount that slides into the clamp of many tools.
Starlock is different. Tools with a Starlock mount, found on newer Bosch and Fein models and some Makita ones, take only Starlock blades. The PECHAM and LEILUO listings both say their blades do not fit Starlock tools, and the XXGO listing says the same. If your tool is Starlock, none of these is the right purchase.
For everything else, check the tool brand and model against the listing before ordering, and read the exclusions as carefully as the fit list. The XXGO not-fit list includes Dewalt cordless tools, Fein Multimaster and Black and Decker, even though Dewalt and Fein appear in its fit list. The PECHAM listing says the set is not suitable for the Dremel MM40 and MM45 in one bullet and that the included C-clip adapters fit those models in another. “Fits 95% of tools” is a seller’s estimate, not a guarantee, and your tool’s manual is the authority on what may be mounted. The DEWALT set is the only pick whose maker describes it as universal fitment without an adapter.
Blade materials and tooth shapes
High carbon steel (HCS) is sharp and inexpensive. It is for wood, plastic and drywall, and one nail can ruin it.
Bi-metal puts harder teeth on a flexible body. It survives nails, staples and soft metals such as copper pipe far better, and it is the everyday choice for renovation.
Carbide teeth are for screws, bolts and other hard material. None of our five picks is carbide. Our catalog does list a five-piece AMZBSAW carbide set aimed at bolts and screws, rated 4.3 stars from 622 owners, and for thicker steel an angle grinder is the better tool; see our cut-off wheel guide.
Japanese tooth blades have two rows of ground teeth and cut wood quickly and cleanly. Semicircle blades make long, straight cuts and let you work flush along a floor. Scrapers have no teeth at all.
When the cutting is done, a random orbital sander cleans up the edge; our sanding disc guide covers the paper.
Working safely and making blades last
Follow the tool maker’s instructions first; these are general habits. Unplug the tool or remove the battery before changing a blade, and let a just-used blade cool before you touch it. Wear eye protection, and a dust mask when cutting drywall or old wood. The scraper and knife blades are sharp out of the box; the XXGO listing tells buyers to wear cut-resistant gloves when unpacking them, which is sound advice for any blade set. Let the blade cut at its own pace: forcing it builds heat, and heat is what dulls the teeth. Check for hidden nails, screws and wiring before a plunge cut into a wall or floor.
One caution for scraping jobs. Old vinyl flooring and its adhesive can contain asbestos, and old paint can contain lead. If you do not know the age and makeup of what you are removing, have it tested before you scrape or sand.
Do these blades fit DeWalt, Milwaukee and Ryobi tools?
The listings say so for most of them: PECHAM names Ryobi and Milwaukee, AMZWEI names Dewalt, Milwaukee and Ryobi, and DEWALT describes its set as universal fitment. The XXGO listing is more detailed and excludes some models, including Dewalt cordless tools, so check your exact tool against it before ordering.
Will they work on a Bosch or Fein Starlock tool?
No. The PECHAM, LEILUO and XXGO listings state that they do not fit Starlock mounts. Starlock tools need Starlock blades.
Can a wood blade cut through nails?
A high carbon steel wood blade will lose its teeth on a nail. Use a bi-metal blade such as the AMZWEI set, or the DEWALT DWA4203 wood-with-nails blade, when nails may be hidden in the cut.
Which blade cuts screws and bolts?
A carbide blade. None of these five is made for that, and the AMZWEI listing says plainly that its bi-metal blades are not suitable for bolts or screws.
How long do low-cost blades last?
Not as long as premium ones. Owners of the PECHAM and AMZWEI sets say the blades dull or wear fairly quickly, and that the low cost per blade makes up for it. We have not measured blade life ourselves.
Bottom line
Buy the PECHAM 24-piece kit if you want a drawer of blades for general work, or the DEWALT DWA4215 if three good ones will do. Add the LEILUO Japanese-tooth set for fast cuts in clean wood, the AMZWEI bi-metal blades for wood that hides nails, and the XXGO scrapers when the job is glue, caulk or flooring. Whichever you choose, confirm the mount against your tool model first.
