Can you use Dremel bits in a Rotozip?

Yes, you can use Dremel bits in a Rotozip, but the tools have different motions. Using the bits on the Rotozip comes with cons, and there is some overlap in their bit sizing. Dremel uses bits ranging from 1/8 inch to the least 1/32 inch, whereas the Rotozip uses 1/8, 5/32, and ¼ inch bits. 

Using Dremel bits in a Rotozip depends on the models and sizes of the bits, and it also depends on the project at that particular moment. Compatibility is one factor to consider, and the Dremel bits have to be compatible with the Rotozip. 

Compare the speed of both tools since they have to match. If the Rotozip is faster than the Dremel, the cutoff wheel will fly apart. The Dremel is small and meant for small areas, and surfaces and the Rotozip should be small.

The Rotozip Spiral saw uses a cutting technology that involves things, cylindrical bits. These are similar to drill bits, and that makes lateral cuts along the shank possible. That means with the right but, you can use Dremel bits in a Rotozip. 

Using Dremel bits from a Dremel tool of the same speed as Rotozip will give you small results. The bit cuts through any building material up to 1inch thick, and the matching speed makes the switch of bits easy since the performance remains the same. 

You need the experience to use Dremel bits on Rotozip. Even if you know how to use them, be safe and careful. Your zipping off will be in the wrong direction. Since they both have the 1/8inch bit, it means you can use the Dremel bit on Rotozip. 

Different motions make it difficult to switch bits, and the model and size have to match for a successful operation. Dremel also makes spiral bits that allow it to cut through the material. However, its tools do not come with the torque of the Rotozip, and that is a small router. 

That means you can use the bits on Rotozip, but the cutting process becomes slower. Slower means it is possible, although using the right tool with bits yields better results. The Dremel bit might not be able to withstand dust generated from the DW. 

Why use Dremel bits in a Rotozip

Dremel uses bits ranging from 1/8 to 1/32 inch, whereas Rotozip uses bits from ¼ to 5/ inches. That makes the Dremel limited in terms of applications it can work on. Since Dremel is more versatile than Rotozip, switching bits makes the Dremel a hybrid tool. The cutting performance increases since the Rotozip majors in cutting. 

Since both of them use 1/8inch bits, that means you can use the bits on any of the tools. It becomes tricky on different bits sizes since that compromises compatibility.

The above tools belong to different groups and what makes them similar is the cutting feature they both offer. Dremel is a rotary tool, whereas Rotozip is an oscillating tool. That brings a difference in motion. Dremel spins, whereas Rotozip has its blade moving back and forth. Since both cut materials, there are chances of swapping bits, and they still bring the same function. 

Since Dremel is more versatile than Rotozip, you might go for it if you choose one Dremel tool. However, that should not stop you from making your hybrid tool in Rotozip that uses Dremel bits. If you have both cutting tools, use the correct bit to bring the intended results. 

What makes a good bit for Rotozip


Take a look at the material used to make the bit. It has to last long so that your drill bit remains better when performing. A durable bit is a high-speed steel, and that way, the drill bit withstands high speeds and makes the tool faster. The carbide used has to be strong and durable.

Ease of use

Complexity does not mean high performance.  The bit has to be easy to use, and do not spend more time inserting it into the tool. The start of the cut has to be easy for precision.


The bit should work on multiple materials, and that makes it convenient. These include steel studs and aluminum sidings, and you do not have to buy bits whenever you are working on a new application. 

Special bit

The bit has to allow plunging directly into the metal, and it has to cut through up to 18-gauge steel. 

Dremel or Rotozip

Each tool has its pros and cons, and you might have a time choosing between the two since they both have unique features. They are both multi-function tools, and what matters is what one gives that the other tool does not have. 

What you intend to use the tool on determines the best tool for your projects. Dremel is a versatile tool for grinding, carving, polishing, and cutting, whereas Rotozip is a contactor tool for cutting sheetrock and ceramic. That makes Rotozip a professional tool. 

It withstands the pressure that comes with everyday use. The Dremel is for tiny places as compared to the large Rotozip. Rotary tools spin bits like a drill, whereas the Rotozip moves the bit back and forth. The Dremel uses a spinning motion. The Dremel Multi-max is closer to the Rotozip since they have a similar motion. (Source). 

Rotozip is bigger than Dremel, which makes the Dremel comfortable to use, and Rotozip is more of an oversized pencil. The power difference lies in the Rotozip having a bigger motor than the Dremel, and Dremel is ideal for smaller projects. 

Rotation is more dedicated to cutting than Dremel, and that is why it cuts faster. It comes with multiple cutting bits you have to choose from. To master high performance, choose the correct bit. It gives you the 360-degree cutting ability and cuts plywood and sheetrock faster than Dremel. 

Dremel is meant for sanding and grinding, and it is ideal for the user with a tight budget. It comes with a dust vault that minimizes flying dust, and that makes it safer than Dremel. Rotozip is faster than Dremel. Dremel gets much hotter than Rotozip, and ventilation is key in the areas. Both have unique accessories and attachments.
