Tools, Sharpening and Power Machinery - What router bit do I need?

I have never used a router before but I borrowed one. I am going to use it to trim around the edge of the formica I glued down to the counter top. I was told to use the thinnest blade I can find, but can someone please tell me EXACTLY what I need to use? Any thing I have read about formica suggests carbide, and a carbide cutter is what I used to cut out the counter top size. So, what size and what material should the router bit be made from? Is there a tool easier or better for trimming the formica? Any advice is welcome as I don't want to mess it up!!!!!

Thank you in advance!!!

noguru,

You want to use a piloted flush trim bit - it has a bearing on the end of the bit for a flush cut. For one time use a HSS bit is okay. If you plan on cutting alot of laminate then get a solid carbide bit.

these bits come in 2 styles - straight and taper (I think the taper is 7 degrees). Ideally you should have both but depending on the amount of work to be done, you could get by with just the straight bit. The taper is for relieving the edge slightly so you don't have a sharp edge to catch things on. If you only have a short length, the same can be accomplished by running the striaght bit and then using a file or sanding block to back bevel the cut edge.
