I use a 1.5mm and so far it has worked ok. Of course the depth of cut and feed rate will be the man factor. the density of the wood also plays a major roll.

I’ve been experimenting on doing inlays. Not the V-carve style but with thin veneers. I’ve used a 1/8" endmill but I would like to get finer detail in the “corners”. I’ve avoided trying a 1/16" end mill because, at least the Amana one, is 50% more than an 1/8" and I would expect that they would be easy to break. So I was wondering how fragile they are from someone who uses them?

I’ve got some cheap chinesium ones that have performed well. I do 50% dia DOC max and run at the appropriate feeds and speeds to have correct chip load.

I use this Amana 1/16 5.4 tapered ball nose in almost all my finish 3d carvings. This bit is a beast, I did this last supper piece at 60ipm in basswood finish pass with this bit. 173550703_152130510164376_1864851114514643155_n884×568 57.8 KB

For slotting, peripheral cutting, plunging, and profiling applications. Square end mills will leave the bottom of your CNC project flat and the corners square.
