MDF Door Bits, Where to find?

[Anders Brannmark]

Found these MDF door bits:

But these are with 1/2" shanks. My hand router can only handle 1/4" and 5/16" shanks. So anyone know of a version that has thinner shanks? Going to make doors and would like to make them out of 1 piece MDF so they dont flex in the joints.

Anyone?

You are going to need a different router to do that kind of work. Routers with 1/4" collets only are not powerful enough to do the job and I don't think you will be able to find a bit that will hog out that much material with only a 1/4" shank.
