After all, the metal of the fret saw blade is harder than aluminum, so why wouldn’t it be able to cut aluminum? That must have been the unconscious idea that crossed my mind when I saw that the saw for cutting metals wouldn’t make a good curved cut and I started thinking about how to cut aluminum in another way. You can also see how to cut aluminum profiles at home.
I need to cut some curved aluminum pieces for a DIY project, but with the metal saw I would need to make several straight cuts and then touch up the curve with a grinder or a file. And with the blade of my metal bow saw already very worn, the cut was becoming very tedious. Since I saw the fret saw for woodwork at that moment, I thought I had nothing to lose by trying. And you can see that the result was quite good.
On the left, you have a photo of the saw I used, which is also seen in the video. It’s a regular, rather poor-quality hand fret saw.
The fret saw blade is also a standard blade for cutting wood, although with slightly larger teeth than I usually prefer, which are smaller and give a finer cut. I made a mistake when buying them and “luckily” now I also have these with larger teeth. And I say luckily because I’m not sure if the smaller-toothed fret saw blades would have been able to cut the aluminum. Maybe, but it would have taken more time for sure. I needed three and a half minutes to make that cut in the photos. And you can see in the photos and the video that they handled the task of cutting the aluminum with hardly any wear.
