Which end mill to level my acrylic bed?

[HankMcSpank]

Thanks guys.

i'm using acrylic cos I have a ready free supply of it! (which normally helps sway the argument in my books). Re screwing stuff to it....I just have my cnc pepper it with clamping screw holes.

It's very flat....it doesn't melt (it's cast acrylic not extruded...the latter gums up the cutting bit).

EDIT: Having just watched a couple of youtube videos, woaah fly cutters rock - I want one! Mark what diameter is the business end not the shaft but the end that holds the cutter)...I've a mini lathe collet that holds up to 20mm diameter - & do I need the dcmt insert holder you mention?

My bed is reasonably flat, so when I bolt the acrylic sheet down to it, I'm only going to be skimming something like 0.2mm off it. (also my bed area is small so could go with two runs of 0.1mm)
