Randy,
Yes that is what's known as a toolmakers reamer. Easy to make from drill rod or drill blanks and works great. Guy Lautard shows how to make them in "The Machinists Bedside Reader" ISBN 0-9690980-2-2 p.53
BTW Guy also mentions that the 1/4" toolmakers reamer makes an unbeatable manicure tool. Also since the cutting surface on a toolmakers reamer is quite simple to make a good reamer can be made from HSS drill blanks on a grinder and hand finish honed with a stone, so no hardening needed.
