Best blade for MDF

One of my projects has got me interested in the public opinion. For cutting mdf, ive always gone with whatever crosscut blade i have on hand and never seem to get any chipout, poor cuts, etc. Id like to hear other guys opinions though. For a 7 1/4 saw, what blade do you use to cut mdf and why?

I'm like you, I've never given cutting MDF any thought and use any blade to cut it. As long as the blade was sharp there shouldn't be any tearing. After all it's just a sheet of paper.

On MDF, I'm more concerned about the wear on the blade than the cut on the MDF. I'm thinking a TCG grind may hold up better than the HiATB's and will probably put on one my 12" slider when I finally replace it.

I've cut a fair amount of MDF in my time http://s29.photobucket.com/user/MrMa...?sort=3&page=1
using many different style blades and agree with John concerning longevity as just about any blade will cut MDF decently. My preference for bare MDF is an 80 tooth TCG (I use an 80T Forrest Duraline HiATB when cutting veneered MDF however the HiATB does wear quicker) and periodically I just clean the build up on the sides of the teeth with a brass brush. BTW, the longest lasting TCG blade I have used was the older style Freud 80T TCG with the black Teflon coating that has been discontinued however I actually found a brand new one of those on eBay a while back which is holding up better than the previous newer style Freud I was using.

Yeah, wear is a big issue on any sort of fibeboard. Managed to toast my last good cross blade on some particleboard last week. Good to know that I'm not the only one who just uses whatever though
