Why Choose Dremel To Cut Ductwork?
You might want to install a flow-through humidifier in your room. Or a hot air vent for your furnace. Whichever the case, you need to deal with ductwork.
Now if you want to install a duct, you need to cut and adjust the metal. And you need tools to help you out with that. You can simply use an electric jigsaw or a tin snip to cut the metal.

But you have more good news! Dremel is so easy to use. You’ll be able to cut steel and tin plates in no time once you learn the basics-
You can sand, sharpen, polish, cut, or even remove grout using this amazing tool. And that’s not the best part, Dremel tools are super easy to maneuver. Which makes cutting as smooth and accurate as possible.
That’s why most people prefer Dremel tools for households as they are multifunctional.
Before we dive into the steps of cutting ductwork. Let’s take a look at the types of attachments/collets of the Dremel tool. As we’ve mentioned this tool has a lot of functions. And for every function, a Dremel uses a different collet.
However, you don’t need all the collets for cutting ductwork. For this operation, you’ll need the sanding bit and the metal disk bit. These two collets will help you to get your ductwork job done. This tool will also work in case you’re using a duct board.
These attachments are available in most hardware stores. But we’ve curated a list of the products for your convenience-
You’ll also need ear and eye protection while using the Dremel. There is a possibility of producing sparks. Once you’ve gathered the tool, let’s dive into the steps of cutting ductwork-
Step 1: Set Up The Required Attachment
The first step for you is to attach the right collet to the Dremel. To cut the ductwork, you need to use the metal disk collet. There might be various shapes and sizes. You have to choose the right one. Choosing also depends on the material and its thickness.
Make sure the collet attaches to the Dremel firmly. Otherwise, there’s a chance of severe injury when the collet speeds up.
Step 2: Find Out The Cutting Speed
As Dremel rotates the collet like a mini drilling machine, speed is important. If it’s too fast or too slow, it might damage the metal and the Dremel itself. Usually, for metals, the speed level could be set anywhere between 4-8. You can turn the switch to the required speed.
Now, you might have to refer to the manual while cutting. Because the speed levels of materials are different.
However, it’s time to stop when the motor of Dremel makes a noise. Or if you have to put in a lot of effort while maneuvering the disk along the surface. You’ll have to change the speed settings again.
Step 3: Start Cutting The Metal Ducts
Once your speed level is okay, it’s time to start cutting the metal ducts. You’ll have to make sure the pipe is steady. You can also use a clamp or a vise to keep the ducts firm.
After that, you start pressing the metal disk lightly to the metal surface. You must wear eye and ear protection because there will be sparks. If the metal starts cutting, slightly increase the pressure every few seconds.
You might need a steady hand to maneuver the required cut in your duct pipe. To do that, you’ll need a bit more practice.
Step 4: Sand The Edges
The best part about using a Dremel is that you can sand the edges after cutting. But for that, you need to use a different collet. The sanding bit will add the finishing touches to your cut. You can also insulate the ductwork.
Now you know how to use a Dremel to cut the ductwork.
