Ridgid 65S Stainless Steel Quick-Acting Cutters, 1/4 in-2 5/8 in

I nearly bought one and became hesitant reading the two negative reviews. Found out a mate who's a plumber bought one to do SS pipe in a hospital job. He still had it in the box and dropped it around. I've cut up 5 6m lengths of 300 50.8mm 316SS pipe (19 cuts). I watched the Rigid YouTube on how to use that said to start with a light score to ensure it is on the same track and straight which is the best advise. If you don't you may get some swarf in the rolled cut which will make the rolling lumpy. Or it will roll a helix onto the pipe. I used an old tooth brush to clean out any swarf and it was then smooth again. After cutting about 16 cuts I did stuff a blade, I'd say as I over tightened the cutter. It more or less ripped off the edge and embedded it in the rolled cut. I picked out as much of the hardened material I could but could not get it all so used a grinder to complete that cut. I imagined trying to cut over the hardened cutter material left behind it'd just stuff the next blade. So every next rolled cut I made I used some grease in the groove to ease the cutter and used much less pressure on the cutter. More or less wizzed it around until it got easier and pressure was gone, then only less than a 1/4 turn on knob... seemed to cut much better that way. Less pressure / turns is better and make sure it's tracking...if cutting hard material wipe a little grease into the rolled cut. Great tool I've just now bought my own.

Over the years I have used many tubing cutters to cut stainless steel tubing with little success. I finally bought the Rigid E 635 and it has been great. I have made many dozen cutts and it is still on the original cutting wheel.
