I found some 7/16 round steel rods lost in a corner of my shop and am
cobbling up some small inserted bit hollowing tools. I wouldn't sully
his memory by calling my messies, "Oland Tools".

I have some 3/16 round hss bits, but they seem a bit too aggressive.
Could be my technique since I have used square 3/16 bits without making
too many funnels.

What size bits do you all suggest for these small tools? Also what
length of exposed shaft do you suggest and what reasonable depth should
I expect to hollow to, say in cherry or mahogany, with a 7/16 crs shaft?
