I can use either my plywood blade or a more aggressive blade, if that makes a difference. thanks, Scott texasmasterplum San Antonio, TX July 11, 2007 8:08 PM Post #3725474 I've been told never to cut pvc with a wood blade, but why not buy a cheap cut off wheel so if you ruin it, it won't matter. balvenie Marysville, WA (Zone 7a) July 11, 2007 8:11 PM Post #3725488 I've cut PVC pipe many times on my table saw with no problem. texasmasterplum San Antonio, TX July 19, 2007 8:51 PM Post #3756900 Well, there you have it. balvenie Marysville, WA (Zone 7a) July 19, 2007 9:27 PM Post #3757070 I must mention though, that my plastic cuts have been crosscuts and not ripping a long piece. I suppose if the pipe is fed through the blade too fast there could be a heat buildup which could lead to some of the plastic melting and gumming up the blade. Slow and easy should be no problem. Decumbent Cincinnati, OH (Zone 6b) July 22, 2007 8:30 AM Post #3764714 I went ahead and made the cut. It went very slowly because of the plywood blade. I should have changed out to a coarser tooth. But it went okay and the blade seems okay. Scott fredin December 4, 2007 8:44 AM Post #4259913 Why should not cut it with wood blade. Moricky Ballwin, MO February 5, 2008 6:45 PM Post #4499685 I cut PVC with wood blades quite a lot. There is some wear/ damage to the blade so I use an older blade but the PVC stuck to the sides is not enough to really be trouble. If the blade has took large a set of teeth there is some chance of it grabbing the PVC so it should be fed slowly until you get a feel for how it is going to act. Different pipe size acts a bit different but all seems to work for me.
