Both MSC and J&L carry 1/8 carbide 60 degree D-bit engraving tools.
I have used them on aluminum for small detail work. CNC work is not
usually referred to as point size, but rather as 1/8, 3/16, etc. The
point size varies considerably with the font and style. You need a
high speed spindle for best results.

Dan Falck did some work a while back in which he used Vfontz to
create centerline cuts from Tru-type fonts. He then used a fixed
diamond tipped engraving tool to mark some stainless steel watch
casebacks. I looked in the files area but they were not there, he
must have sent the pictures to me directly. They looked very nice.
