Hi Scott,
Dumb question warning
I'm busy sorting out all my stuff in case I find a buyer for my machine. I bought these bits a few years ago and have never used them. As I recall, they're engraving bits. Knowing you do a lot of fine detail work I thought - if you use Onsrud and only if you have time - you might recognize if they are for fairly general use or perhaps more specialized so I'd know what to call them.
Thanks kindly,
Gerry
