    Talking Cutting stainless steel pipes


    I would like to get some advice with regards into helping my friend's shop.

    My friend who runs a shop does automotive modifying work like turbocharging and exhaust stuff. He uses just a rigid abrasive chop saw and a bench grinder with a wire wheel and a stone wheel.

    I mentioned to him about the dry cut saw and told him that I would research on it first and if its a good investment he might get one. With exhaust works and turbo, he uses SS304 or 316 tube/pipe, and mild steel, they range from a 2" diameter to a 4" diameter. He either tigs or migs the pipe/tubing together.

    When Tigging pipe/tubing, these are his steps (doing exhaust/turbo work)

    1. Cut the tubing
    2. Deburr the pipe using a bench grinder stone wheel
    3. Clean the edges of the tube with wire wheel on bench grinder
    4. Using a sander, sand the tube so its flat
    5. Clean again using a wire wheel
    6. Then tig it connecting to the other pipe

    Sometimes he does some of the steps twice just to make sure its flat and burr free.

    It is very time consuming for them to be doing this and with those time that was used, it could have been used on another part of the car (be more efficient).

    I guess my question is mainly, what would be the best tool to use in cutting Stainless Steel pipe/tubing for exhaust/turbo work? That of course would greatly minimize the burrs? In order to just basically cut, quickly clean, and weld?

    Thank you in advance for any help!!!

    Greatly Appreciated

    I saw an incredible saw (heh, heh) at eastec. It was a small bandsaw, made in italy. It ran the blade in the opposite direction we are used to. The guy let me try it. I could cut a sliver off a 3" solid bar very quickly. the taper was about .003", verified with a dial caliper. I was very impressed. they are light and small and run around 1100-1500 depending on the model. I don't know if anybody knows the name, i will try to remember and post if i do. I have a milwaukee dry cut and would trade it in an instant for this one.

    Hi Everyone,

    Thank you for your replies!!! Much help is appreciated

    Actually, my questions applies to both MY own tools and my friend's shop.

    Just for clarification, a "wet saw" is the same as a cold/dry cut saw? Reason why I asked about the cold/dry cut saw is that I noticed on the blade itself that it does not say that i can cut SS? But specify that it can only cut Mild Steel?

    This is the blade I am referring to:

    I myself already have a small band saw (horizontal), and a 14" chop saw. My band saw currently is broken due to the blade, and eventually would like to get it replaced and calibrated to some sort due to the fact that it does not cut straight (thats why I dont use it much before it broke). I just got my chop saw so I havent used it much.

    But I dont cut much pipes as I am just a hobbiest, as much as my friend's who runs a automotive shop business.

    Basically, I would recommend my friend to either buy a band saw or a cold/dry cut, but I would like to first get a confirmation that it is ok to use Stainless Steel on a cold/dry cut saw?
    (Leaning towards on getting a cold/dry cut saw thats why)

    Thank you!

    Cleaver, as you can see, a lot comes down to your (friend's) budget. Cold saws are nice. Nice and pricey. Dry cut saws are more economical, but I'm not sure that would be my choice of machine. Noisy, too. Ouch.
    I like bandsaws.
    You already have a bandsaw. Get some blades, dial it in the best you can, and get 'er done. IMO, the kind of work you are talking about is all about proper fit-up and patience. I don't think you will find a magic tool to get it done without some post-cut tweaking for fit-up.

    I agree with Ironhead and Jack's approach... not necessarily with the same equipment they recommend, but in a nut shell it's suggesting that you don't need a $5000 saw to cut on the line. This is just my $.02. If your buddy has a shop, a cold saw could serve him/you well for a variety of applications... but it's not necessary IMO. See if you can't try one out somewhere on the material you are looking to work with and then you can make a better call for yourself.

    This is the method we use out in the field but we also use these pipe cutting guides

    Hello Cleaver!
    If I understand your friends need from your post, he seems to have a need for prototype/modification work, as opposed to production.
    Since he is in the business of making money with the needed equipment, he should only invest in quality equipment. I think a miter bandsaw, and a belt sander would be a good start, and then a cold saw with appropriate blade for type of material as the need arises. There are plenty of good quality brands to choose from, but he will need to find a good local supplier, and find a product that has the best service locally. I would have them demonstrate the equipment first before any investment too! The good companies like Dake, Brobo, Scotchman, Doringer, and Burr-king are more than happy to help and advise on the type of equipment that will be needed.

    The saw blade you linked to is for a dry-cut saw. I doubt it will work with a cold saw which is completely different. A dry saw is similar to the abrasive chop saw in construction, but with a different style of electric motor. You have to purchase the blades recommended by the manufacturer for these type of saws. Milwaukee has one that is hand held, and used like a circular saw. Run a google search on dry-cut saw, and cold saw and you will understand the difference
    I hope this helps!

    This is a genuine procedure that we can implement. There is also one option for cutting a stainless steel using a lathe machine. It is simple and no risk.

    Cutting straight tubing on a lathe is fine, but most of what I work with is either thin wall structurals or mandrel bent tube, so that's not really an option.
