Which end mill to level my acrylic bed?

[blackburn mark]

i'm using acrylic cos I have a ready free supply of it! (which normally helps sway the argument in my books).

yep.... that'll about do it for me to :)

woaah fly cutters rock

to right they do :)

what diameter is the business end not the shaft but the end that holds the cutter

19.8mm (ish)

do I need the dcmt insert holder you mention?

not at all... thats just me being lazy...just try to put a "small" radius on your tip when your sharpening your tool

I wonder if a disc style with a single vertically mounted cutter may be better for this, as it'll be more balanced?

the theory is good but iv had no problems getting lovely finishes with this one at 1500/2000rpm
