Terry, I'll bet all those binding bits are made by the same company and just branded differently. Mine say Wintersteiger on them 3.6x9 and 4.1x9. I've seen Montana and other brands too. They also have a nice sharp point that won't wander as easily from the punchmark as a standard drill bit
Ski rat, you'll need the 6.5?mm version for inserts. The one sold by binding freedom has a stop. Mine's pretty old and I don't think chamfers the hole like the Wintersteiger/SVST/Montana/???.
