I thought this was simple I need to make some 2.5" rosettse but see there are kits that take carbide bits and regular cutter. I am a little lost on who makes a good one. This is for around my house so it probably won't get much use. Idealy I would like to get a 2.5 and maybe a 2" or 3" with the same profile. Any recomendations or am I just researching this to hard.
