Best Saw Blade for MDF - Woodworking Talk
If you will be cutting quite a bit of MDF, a blade with a triple chip grind (TCG) will keep an edge better than most. You don't mention whether you're looking for full kerf or thin kerf, but on the bargain end, the Oshlun line from Holbren, Amazon, or Eagle America is surprisingly good for the price. The Freud Avanti TK series is also a good value.
