An oscillating multi-tool can make plunge cuts, scrape residue, remove grout or detail-sand, but the right package depends first on power source and included equipment. We reviewed current manufacturer pages and manuals for three exact models. HandyTested has not cut, sanded, timed or vibration-tested these tools, so performance statements below are limited to documented specifications and package details.
Quick comparison
| Exact model | Power and control | Package distinction | Best fit |
|---|---|---|---|
| DEWALT DCS356B | 20V MAX cordless; 3-speed selector plus variable trigger | Tool only; two blades and adaptor, no battery or charger | Users already invested in compatible DEWALT batteries |
| BLACK+DECKER BD200MTB | Corded 2.5A; 6 settings, 10,000-20,000 OPM | Blade, sanding base, sheets, adaptor and bag listed | General household work near an outlet |
| WEN 2312 | Corded 1.8A; variable 15,000-21,000 OPM | Current product page describes a kit; verify contents | A compact corded option with broad accessory support |
A bare tool can cost less at checkout while requiring a separate battery and charger. A corded kit avoids battery-system lock-in but needs outlet and extension-cord planning. Prices and stock change, and none of these models is guaranteed below a fixed ceiling.
DEWALT DCS356B: cordless bare tool for existing 20V MAX users
DEWALT identifies DCS356B as a brushless 20V MAX cordless oscillating multi-tool with a three-speed selector, dual-grip variable-speed trigger, tool-free Quick-Change accessory system and LED work light. A universal adaptor supports most oscillating-tool accessory brands. The listed package includes the tool, two wood-cutting blades and adaptor.
Trade-off: the B suffix is important: this is a tool-only package. Battery, charger and guide system are sold separately. Its practical value therefore depends on whether you already own compatible batteries and on the blade required for the material.

BLACK+DECKER BD200MTB: corded kit with tool-free changes
BLACK+DECKER documents a 2.5A corded motor, six speed settings from 10,000 to 20,000 OPM, a quick-release lever and tool-free accessory changes. The manufacturer lists a wood/metal blade, sanding base, 12 sanding sheets, universal accessory adaptor and storage bag with BD200MTB.
Trade-off: unlimited corded runtime does not mean unrestricted movement. Plan for a correctly rated extension cord and keep it clear of the cutting path. Universal compatibility still requires checking the specific blade and adaptor arrangement before use.

WEN 2312: compact corded variable-speed option
WEN lists model 2312 as a 120V, 1.8A variable-speed multi-tool operating from 15,000 to 21,000 OPM with a 6 ft power cord. Its universal adaptor accepts most brand-name accessories, and the manufacturer describes cutting, grinding, sanding, scraping and grout-removal applications.
Trade-off: WEN’s current page calls this a kit but does not present a clear accessory inventory in the main specifications. Verify the seller package before buying. The correct blade and speed depend on the workpiece; a higher OPM number is not by itself proof of faster or cleaner cutting.

Choose the blade before the tool setting
- Identify the material and task: wood, metal, grout, scraping and sanding need different accessories.
- Confirm that the accessory mount or supplied adaptor fits the exact tool.
- Disconnect the plug or remove the battery before installing or adjusting an accessory.
- Inspect the work area for hidden wiring, plumbing, fasteners and other hazards before cutting.
- Start with the manufacturer’s recommended speed and technique rather than forcing a dull or unsuitable blade.
Wear suitable eye protection and use hearing and dust protection for the task. Secure the workpiece, keep hands and cords away from the accessory, and allow hot blades to cool before handling. Follow the exact tool and accessory manuals; an oscillating tool does not make an unknown wall cavity safe to cut.
How to choose
Choose DCS356B when cordless movement and an existing DEWALT 20V MAX battery system matter more than receiving a complete kit. Choose BD200MTB when a corded tool with a clearly listed starter set and tool-free changes suits household projects. Choose WEN 2312 when you want a compact corded model and will verify the current accessory package. In every case, compare the exact model, power source, included blades, accessory interface, warranty and checkout price.
Frequently asked questions
Can one oscillating blade cut wood and metal?
Only when the blade manufacturer rates it for both. A wood-only blade can be damaged by nails or metal. Match the blade to the material and replace worn accessories.
Is a cordless bare tool cheaper than a corded kit?
Not necessarily. Add the cost of a compatible battery and charger if you do not already own them, then compare the actual package and current price.
Were these multi-tools tested by HandyTested?
No. This comparison is based on current manufacturer documentation and clearly stated package limitations.
