Oscillating tools, both cordless and electric, are excellent multi-purpose tools. They serve the purpose of several tools in one convenient package, rather than relying on several separate tools. For example, a single oscillating tool can be used to cut, sand and grind in multiple applications. You get the use of a saw, sander and grinder all in one tool. It can be far more convenient to have an oscillating tool that can perform all these tasks, instead of three separate power tools that you would have to transport and set up each time you need to use them.
Oscillating tools (often called "oscillating multi-tools") are power tools that use vibrations generated by quick back-and-forth movements to cut, sand, polish or scrape a wide variety of materials. They are ideal for a number of applications, including sanding, cutting, grouting, refinishing, buffing, restoring, plunge cutting and flush cutting. Many people, professionals and hobbyists alike, enjoy using them because they are a handy, all-in-one solution that takes the place of several tools. They can be used in many professional and hobbyist tasks like remodeling, finish work, construction, tile work, woodworking, flooring, etc. They are available in electric and cordless models. Though similar, oscillating multi-tools are different from rotary tools. Oscillating tools employ a fast back-and-forth movement, while rotary tools use a spinning motion in a fixed position. Rotary tools also tend cut a bit more roughly because they spin at high speeds.
Types Of Cordless Drills
Electric Oscillating Tools
With electric models, you don't have to worry about run-time while you work. As long as there is a power source (outlet), you can power your oscillating tool without problems, and work for as long as you want. Plus, you can take on heavier duty or lengthier projects since you have a constant power source. One downside of electric oscillating tools is that they have somewhat limited access. You can only work as far as the cord will reach. Otherwise you're stuck with having to find available power outlets or running an extension cord to reach certain work areas.
Cordless Oscillating Tools
Cordless oscillating tools are convenient to use. You can use them anywhere as long as you have a charged battery to power it. Being cordless means they are also portable, which is great for finishing tasks quickly. However, you are limited on the run-time. You can only work as long as your battery is charged. If you forget the charger or didn't charge it before you planned to use it, you're stuck waiting on the battery, which costs you work time.

Each type of blade listed above is explained in general terms, but every blade's capabilities and uses are different depending on their design and construction.
Before You Buy
There are several things to consider before buying an oscillating tool. Figure out what qualities you want. Is portability most important? If that's the case, then a cordless one may be best, as it enables you to work without worrying about always having an electrical outlet within reach, as you would need with an electric one.
Consider the type of work you will be doing. If you're a professional who needs an oscillating tool for day-to-day jobs, your needs are probably different from a hobbyist who does occasional home projects. An electric one is a good option if you need a constant source of power. A portable one could be somewhat inefficient due to all the battery recharging you would have to do. But if you only need it for occasional home projects, a cordless oscillating tool may be the right option.
Ease of use is another factor to consider. Some electric oscillating tools may weigh less than portable ones, but you also have to consider that it's corded. That may limit reach and where you can work, as you can only go as far as the cord stretches and you will always need a nearby outlet. At the same time, a portable oscillating tool might be easier to use because it's not bound by a cord. However, it may weigh a bit more because it's battery powered and carries that extra bit of weight.
Also, think about how much you want to spend. You can find many affordable oscillating multi-tools for less than $100, but high-end, professional-grade ones can run several times that, with some costing close to $1,000. If you're a professional in need of a high-quality oscillating multi-tool for regular use, then it may be worth it to spring for a more expensive model. But if you're a hobbyist or only need one for occasional/home use, you can easily find an affordable oscillating multi-tool for anywhere between $100 and $200.
Should I opt for an electric or cordless oscillating tool?
Whether you choose an electric or cordless oscillating tool depends on how you plan to use it. If you need to work continuously and often on heavy duty, long-term projects, go with an electric oscillating tool, since it has a constant power source and will be able to power you through numerous tasks. If you prefer something more portable, a cordless is fine. Just be prepared to charge it periodically and know that its capabilities may be limited (run-time, etc.) with its limited power source.
What sorts of applications can an oscillating tool be used for?
Oscillating tools are one of the most versatile power tools available. Depending on the attachments you use with it, an oscillating tool can be used for sanding, cutting, grouting, refinishing, buffing, restoring, plunge cutting and flush cutting. Oscillating tools can be used for both professional and hobbyist applications, including remodeling, finish work, construction, tile work, woodworking, flooring, etc.
How big of a project can I use an oscillating tool for?
Oscillating multi-tools are perfect for smaller scale projects, such as removing grout, scraping gunk, sanding small sections of wood, making straight-edge cuts, removing trim, trimming flooring, cutting nails/bolts and cutting pipe. Oscillating tools work great for these types of applications because of their convenient size and efficient power. You could try to use a large power saw to trim flooring or make a straight-edge cut along something like a doorway or cabinet opening. But their bulky, larger size makes them more difficult to handle, especially in smaller spaces. Oscillating multi-tools can also be used during parts of larger-scale projects, like remodeling a kitchen or refinishing a basement, but they shouldn't be the the only power tool you use. They work great during the small-scale portions of larger projects, but it wouldn't be efficient to use only an oscillating multi-tool, as they are typically not powerful enough.
Can I use attachments of a different brand than that of the oscillating tool?
Depending on the brand, some oscillating multi-tools can be used with the accessories and attachments from different brands. However, it's best just to use attachments that are from the same brand as the oscillating multi-tool you are using. They are specifically designed to fit that particular model and will work best with it. Using the accessories of one brand on the oscillating tool of another brand can be a bit risky. For instance, you run the risk of the attachment not fitting properly or not locking into the oscillating tool, which can hinder tool performance or damage the work piece. However, some oscillating multi-tools are compatible with the accessories of different brands, and in that case, you can mix and match accessories with the oscillating tool. For example, the Milwaukee M12 Cordless Lithium-Ion Multi-Tool is compatible with some of Bosch's oscillating multi-tool attachments. If you choose to mix brands, be sure to research both the oscillating tool and the accessories to make certain they can be used together.
