              You said ss pipe, not tube. What are you cutting and why. Do you care what the cut looks like, ie do you need a good square to weld to or cut a thread on. Or are you junking it? The tube cutter you ask about will not cut 2" sch 40 ss pipe, at least not more than once.

              I'd use a porta band if you dont need a square cut. Its the fastest and least mess.

                No re-attaching. Demoing it away. Makes sense. Thanks.

                  stainless is one of the hardest most difficult metals to cut.

                  a grinder will work, if sparks are not an issue. forget the sawzall. the blade will be toast.

                  a porta band with slow speed and coolant will work, but not too many porta bands will tolerate coolant.

                  a 14'' high speed cut off saw, plasma cutter, or cutting torch will easily cut it. but sparks are going everywhere.

                  stainless is worth good scrap value too.

                      Rick how much are you guys getting for yur scrap - stainless steel, copper & brass???????????????

                      BTW, INOX blades are the best for S/S. 1mm thick and minimum sparks. Easy cleanup if you are using it again too.

                        a porta band with slow speed and coolant will work,
                        He said this is coming off an outside wall. Sounds to me like he will be working above grade from a scaffold or ladder. The only tool that I would choose under those conditions is a porta-band. A porta-band will cut 2" SS all day long. Yes, you will use a couple blades but if you don't twist the blade and use low speed it will make many cuts. I have done so many times fabbing small bore SS socket weld pipe. I've made many, many cuts on 3" and 4" sch 160 316 SS with a portaband. And I'm talking the original Porta-Band made by Rockwell in the 70s. I never used a coolant and neither did anyone else. It will just jam up the saw with swarf and coolant and you'll have blades jumping off the wheels every couple seconds. I would not use a coolant or lubricant, use the saw dry as intended. Choose the proper blade (TPI) for the material being cut. Use the same guidance you would when selecting a hacksaw blade, the rules are the same its just powered by a motor not your arm.

                            Yes but not needed for a porta-band. Its great for drilling and tapping.

                              Did someone say Stainless? I have worked with it a lot. I just bought the new milwaukee metal cutting saw and stainless steel blade. We cut 1/4" thick stainless plate to build Porta potties for a park. I did find out something to use that I did not know about. If you have a 4" grinder. They sell thin abrasive blades marked for stainless steel at home depot. They are cheap. Works great on all types of metal. 2" stainless would probably eat through 2 blades. If you have room to swing black iron pipe cutter, you can buy a wheel for that, or if just making one cut, use the wheel that is in it. I have cut and thread miles of stainless.
