In my opinion, a previous comparison of CBN insert geometries (availables in catalogs), that seem to be rater limited for the moment compared to variety of those in carbide, could be a good starting objective for this rather interesting study.

MDF seems to be a very abrasive material for classical uncoated HSS tools.

Some papers found online. Could help.

Bests regards

 Thank you for the answer and links to the publications.

MDF really is processed using a heat resistant tool materials than high-speed steel. Apply hard alloys.

When using the CBN is important to select the geometry of the blade. Important blade strength and surface quality.

Belarus has experience of CBN tools for metalworking. But other metal cutting blade geometry, other cutting speed and feed.

Thanks again.

We work MDF in a router CNC with integral hard metal milling cutters coated by TiNAl, and the performance is really good. 

Thanks for the info.

In Belarus, we tried to mill chipboard using cutters made from tungsten carbide with a TiAlN vacuum-plasma coatings. Increase the resistance up to 80 percent.

The coating does not sink on steel?
