Will these work with copper?

I know they will work with ferrous metal. I've used them to cut conduit. But I want to do something with some copper tubing. I don't want to cut it all the way through, so a tubing cutter will not work.

 

I suppose I could use a hacksaw, but if these will work it will be so much quicker.

A tubing cutter won't go all the way through if you tighten it in minimal increments. If you don't want the indentation so sharply embossed, you could always intentionally dull a tubing cutter wheel.

You could use the Dremel style bit/cutting wheel pictured also if you practice and have a variable speed tool as they are hard to control without practice.

 

Good luck.

I'm thinking about making a moon clip demooner.

I've made them out of steel. A piece of electrical conduit would work wonderfully, if they made 3/8 electrical conduit but I have not seen any of that.

 

I have some heavy wall copper tubing, and a 45 drops down it nicely. So I need to cut that little tab onto the end.

 

You can see why a tubing cutter would not work.

 

This might not work - the copper might be too soft, and bend instead of prying the empty case out. But the only way to know for sure is to give it a try.

I have used those on copper tubing with no issue.

Ya beat me to it. I have also used those on aluminum. It’s a cutting wheel, not a grinding wheel. 
 

Alpo, please wear eye protection. :)

I know that I'll probably regret asking, but why? If the answer is "Just to see if I can," I'll understand, but knowing you, Alpo...:P

Because I'm too cheap to spend 20 bucks on a store-bought one.

 

If I can make one out of scrap I have around the house.

Back in about 91 some guys at work made me one. On company time, using company equipment, and starting off with a company owned 4 inch long 3/8 stainless steel nipple. That worked fine. It disappeared 4 or 5 years ago.

 

I've got one of these

And it works, but I prefer the other type.
