Airstream work requires 3 different numbered drill bit size, for doing first class work.
# 30, # 21 and # 11.
Any size over that will guarantee poor workmanship.
The factory drill bit for a 1/8 pop rivet is # 30.
# 30 drill bit is .1285 or 3 1/2 thousands over a 1/8 rivet.
# 29 drill bit is .136 or 11 1/2 thousands over a 1/8 rivet.
As you can see, the # 29 is way to large to do anything except a sloppy job that most likely will fail in a very short time.
