How do you cut stainless steel ductwork?

If you’re working with stainless steel ductwork, you’ll need to know how to cut it properly. Stainless steel is a tough material, and it can be difficult to cut through without the right tools and techniques. Here’s what you need to know about cutting stainless steel ductwork.

First, you’ll need a good quality saw blade that’s designed for cutting stainless steel. You’ll also need a cutting lubricant to help the blade move smoothly through the material. Apply the cutting lubricant to the blade and the area you’ll be cutting before you start.

When you’re ready to start cutting, use a slow and steady motion. Don’t force the blade through the material, as this can damage the blade and cause it to bind. If the blade starts to bind, stop cutting and carefully remove the blade from the material.

Once you’ve cut through the stainless steel, you’ll need to deburr the edges. You can do this with a deburring tool, or you can use a file. Be sure to remove any sharp edges from the stainless steel before you move on to the next step.

Now you’re ready to install your stainless steel ductwork. With the right tools and techniques, cutting stainless steel ductwork is a breeze.
