you can almost cut it with a toothbrush (G) I usually use a straight bit and climb cut when I cut letters as they stay in place that way. but a upcut works fine too. I usually use a climb cut as that causes the shavings to somewhat stick to the scrap and the part stays in place well. I have cut the 1/4" with a 1/16" bit when I needed really small letters.
