: MDF is great stuff... smooth, easy to work with, easy to finish, sturdy. Only caveat: it eats router bits for lunch. Geez. There's something demoralizing about staring at a worthless piece of scrap metal that five minutes previous had been a $10 router bit.
Just a quick note about bits, solid carbide is very durable, but won't have as sharp an edge as a high-speed steel bit. However, it will keep that mostly sharp edge for a longer period of time.
A friend of mine who has been in woodworking for about 20 years says that you are better off buying 3 or 4 high speed steel bits (at about $4 each and which can be re-sharpened) than a more expensive solid carbide bit (about $15) which dosn't perform as well, but lasts longer.
Not sure how this applies to your situation, but I thought I would pass on the info.
