Does it plunge well? Know of any good prices on straight flutes?

You should use a spiral lead-in because they are not designed to plunge straight down, I use them all the time.

Thanks, but isn't that a router bit? I'm talking CNC btw.

Ha, the router bit has no idea nor cares whether you are using a router or a cnc, in fact I'm suprised you thought there was a difference. (where we are talking about wood products)

Sorry I thought they were different. I just found a straight fluted mill bit that can plunge (specifically for CNC). Will give one of those a try. Thanks for suggestion. :)

Plunging is fine but there comes a time when you should look at lead-in moves. What CAM software are you using ?

Solid carbide up-cut double flutes spiral router bits are also a good choice for MDF cutting. Two large grooves can easily remove chips and keep bits in balance during rotation. They are also high temperature resistant, and tungsten solid carbide can guarantee a long use life.
