Hi,

It is for my DIY CNC with a (8000 to 25000 rpm router)

I tried several type of cutters and what works the best so far is a 4mm chinese 2 flutes upcut with TiN coating. Helix looks 45deg. This cutter performed better than my carbide 1/4 2f upcut spiral or straight cutter.

Since there's no such thing as a "cutter datasheet" for chinese cutters, I set my chipload to 0.005 and the result is ok; not stellar but ok.

What would be the best tool to cut solid surface (Corian) ?

Thanks
