Thread: A question of Mdf?

Noticed when cutting small tables, the edges (even with a new bit) are very furry.
I know a compression bit is the answer but they are expensive and upper cut spirals have worked in the past.
Is it the quality of the mdf? It seems, the lighter colour it is, the better it cuts (or is that just a coincidence?)
Stuff from Builders yards, Wickes, B & Q seems to waver wildly in quality. Where do you get decent stuff at good prices?

Yes, lighter color generally indicates higher quality, often known as super-refined MDF.
I generally use downcuts.Gerry

You should use a spiral lead-in because they are not designed to plunge straight down, I use them all the time.Last edited by EddyCurrent; 17-11-2017 at 11:31 PM.

Solid carbide up-cut double flutes spiral router bits are also a good choice for MDF cutting. Two large grooves can easily remove chips and keep bits in balance during rotation. They are also high temperature resistant, and tungsten solid carbide can guarantee a long use life.

If you get it in small quantities, there is a material called Valchromat which is vastly superior to MDF, and it machines beautifully. It is also coloured and great for furniture building. I'm in the process of using it to make a clock case now.
