Track saw blade

each composite and pvc manufacturer has a recommended blade tooth count, based on size of blade, might review their sites and see what tthey recommned, otherwise, our rule o thumb has been 24 to 32 tooth on 7.25 inch, 40 to 70 on 10inch, again, trex has their recommendation, moisture shield has theirs ect.
pvc decking at least here in Az, is having a rough go, since it moves so much, and with our temp changes from 30 plus or minus degrees to 120 on the high end, they are finding its a tough product to keep in place,

best of luck, heat is not your friend on pvc when cutting,

You can get lubricant sticks. I've never used them so don't know if they work well or not.

What type of blade should be used for ripping 1/2" thick PVC (Azek brand), with track saw?

Thanks!

not all timbertech material is pvc, composite cutting is totally different than that of pvc cutting, but good info regardless.

Thanks, the Azek is going to be used for trim boads, coming in 4' x 8' x 1/2" or 3/8" thick sheets. I've settled on a high tooth count carbide finish blade and the article you posted re-affirms the decision.

Thanks again.

I've found that high tooth counts generate more heat and cause melting, so I use low tooth count blades.

I would use a 24 tooth count blade in a circular saw, and start with a new blade.

I agree on the lower tooth count would generate less heat.

That said, I've cut AZEK on both my miter saw and table saw with no issue using crosscut blades.

Most track saws have a speed control. As speed creates heat, lowering the speed of your blade may help reduce the melting. I would use a low tooth count blade as others have mentioned and try lowering the blade speed. Keep the saw moving at all times during the cut to prevent building up heat in any area.
