looking for saw blade recommendation

[lclore]

I want to cut 3.5" diameter round Delrin on a 14" Ryobi Metal Cut Saw (3900 rpm). In experimenting with some common 12" 200 tooth blades, they are more melting material off rather than cutting and throwing chips. Some of the blades I found on McMaster are $250/ea. Anyone got a recommendation?

I saw delrin regularly with a combination 8-12 tooth blade on a 7x12
cutoff saw , also with a 6tpi blade on a vertical . blade speed is the key
with plastics.

I have cut delrin sheet on my 10" table saw, but use a 24 tooth carbide blade. I think a 200 tooth blade gullets will pack with chips and jam. Also there is too much blade contact with the material at the same time. This will heat the plastic. The problem with the rip blade will be the end finish will be rough with lines and not glass smooth as with the 200 tooth. If you need a better end finish you will have to turn and dress the ends in a lathe after the saw cut has been done.

Good point on the tooth count, also consider using the smallest diameter
blade that will cut thru the material as the smaller dia. results in lower surface speed of the blade and that will reduce the amount of heat
generated . if finish is important you might try a planer style blade.

Good information- thanks a pile. I had a suspicion about the tooth count. didn't want to blow $250+ with McMaster if a $25 blade would work. Thanks again
