I’ve scoured the web and can’t seem to find the answer. Anyone know of a source?? Just wondering how it compares in hardness to say oak or pine, for example.

MDF can vary based on manufacturer, but I’ve always heard it’s around 1100 to 1200 lbs., give or take. That puts it somewhere in between pine (870) and red oak (1290). Based in experience cutting all three, that sounds about right. It’s cuts more
like oak than pine. This is why it makes for good jig and fence material, other than the fact that is reliably straight.

All that said, I don’t especially like the stuff because of the type of dust generated when cut (I size my full sheets with circular saw). However, it is perfectly priced an terrific to use when my wife wants a closet shelf. But I prefer Baltic birch for jigs.
