What is the purpose of these Carbide

I did not find in the wiki site of Shapeoko the type of carbide, in this is for what ?

In the description:

materials including plastics, PCB and metal

I don’t think they’d work well in a trim router given the high flute count and low chip clearing.

That type of cutter is meant for fibrous material. I used one on phenolic plastic and it worked better than a standard carbide cutter but still not great. They make some like that for carbon fiber but I would not machine that stuff.


They are for cutting PCB’s.
