WeldfabNeil Posted February 19, 2017 Report Share Posted February 19, 2017 I have to cut 1" hdpe bathroom partition panels. Will any plastics blade work or what's best? My current plan is just cutting with a circular saw, will probably use a straight edge as well. The finished edge quality doesn't need to be perfectly smooth, it won't be exposed. 1 Quote Link to comment Share on other sites More sharing options...
JimboS1ice Posted February 19, 2017 Report Share Posted February 19, 2017 Diablos non-ferrous metal circ blade is good for plastics, if your looking for a little less expensive blade the CMT brand has a similar bladeSent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
albert.amantea Posted February 19, 2017 Report Share Posted February 19, 2017 The best cut in plastics is achieved by rough cutting with a circular saw, then using a router with a straight bit to bring to final size. It's an extra step, but the quality of the cut is about perfect, with zero chip out or breakage. That's my experience anyway...

SetBuilder Posted February 19, 2017 Report Share Posted February 19, 2017 We use Amana blades for cutting Acrylic and Lexan on table saws and chop saws. https://www.amanatool.com/products/saw-blades/non-ferrous-saw-blades.html I cut a bunch of 1in acrylic recently with a festool track saw, it was then finished by our CNC dept. The Track saw cuts were as straight as can be though. The sheets were 6x8, so I was cutting them to fit onto the CNC machines for the circular shape they needed for the final cuts. I'm not familiar with HDPE though. A non ferrous blade should do the trick, just watch for heat build up. Quote Link to comment Share on other sites More sharing options...
Theultimatehic Posted February 19, 2017 Report Share Posted February 19, 2017 Diablo non ferrous blades are what i use for plastics and aluminum. They work fantastic! Quote Link to comment Share on other sites More sharing options...
WeldfabNeil Posted February 21, 2017 Author Report Share Posted February 21, 2017 Thanks for the input guys. I picked up a diablo 7 1/4" non ferrous blade. I ended up not needing thoe. As I got to there one of the other guys said he had a Dewalt trex decking blade. We sort of looked at it like hmm this might work. With a extra piece we made a test cut. The first cuts were good. Later in the day the blade got dull. It then got really dull an left melted plastic on the side. The last 3 panels we beveled the edges with my angle grinder an wire brush. If we didn't remove the burr it would not of slid into the mounting channel. I would normally like to be confident in my tools an don't use dull blades. It was a volunteer job an the one volunteer had a extra blade laying around his garage. Didn't see the point in spending 50 bucks on a tight budget.
