These two powerful tools fairly look almost the same. Both machines also offer an extensive selection of attachments that provide different uses.

Both of these tools offer similar services such as cutting, sanding, polishing, and finishing. That’s why people often interchange the two. Nonetheless, they also have their unique differences and distinctions with regard to their strength, capacities, and full capabilities.

To eradicate the confusion, we have laid down for you the angle grinder and multi tool or oscillating tool comparison.


When we compare an angle grinder vs oscillating tool or multi tool with regards to maneuverability, an oscillating tool is considered to be more maneuverable.

Its thin blades and attachments make it possible to fit into tight spaces and perform the task with much ease and comfort.

They are also much lighter to carry. But if you need to bring it outdoors, this will be a bit of a hassle due to the numerous attachments that you need to bring along with it.

Angle grinders can also be handled with ease. But their attachments are often larger in size.

This machine should also be used in a large workspace due to the sparks it produces during cast iron pipe cutting, metal cutting, auto body work, and polishing.

When it comes to outdoor job sites, this is more convenient to bring because you will not need to bring tons of attachments for it.


While both of these two tools have their versatile attachment, systems designed to perform a specific task, each of them uses different kinds of blades.

Take note that you cannot use the attachments on an angle grinder for an oscillating tool and vice versa. Oscillating tools often have a straight blade attachment to slice through different materials.

These blades can be used to perform different tasks from removing mortar to cutting wood. Oscillating tools also come with other attachments such as scraper tools, sanding pads, and toothed saw blades.

On the other hand, angle grinder attachments differ entirely. These attachments come as a disc or a wheel which makes cutting, sanding, grinding, and polishing possible.

They also vary in size, RPM level, and level of sharpness.


People that are on a tight budget often prefer to buy oscillating tools. The machine itself as well as the attachments are cheaper compared to an angle grinder.

An oscillating tool often costs around $100 to $180, depending on the brand and quality of the machine.

But when it comes to maintenance you might shell out more dimes with an oscillating tool. They require high maintenance since they have more attachments.

Prices for angle grinders are sure to be way more costly. They range from $180 to $500 excluding the attachments that you need to purchase along with them.


Well, when we talk about probable danger and damage, these two items are not excused. They both represent safety risks. But when it comes to the level of danger and preparation requirement, angle grinders are riskier to use.

Because of its strength and power along with the sparks and debris that may fly around during use, operators are required to use the recommended protective gear and clothing to secure maximum safety.

With oscillating tools, they don’t require any PPE when you operate them because they don’t throw off any debris.

They often have clean operations. You just have to be careful when you’re trying to cut metals.
