The set screw and nut that secures the pilot nozzle to the hole saw is absolutely impossible to loosen - partly because the nut is round, mainly because of the bolt set jams on delivery and cannot be solved with reasonable effort. Maybe not very good quality control, or maybe everything is as intended. Definitely don't buy it if you plan to use the drill bit as a replacement or modify the hole saw in any way; seems impossible!

Only thing I can say is make sure you have a good powerful drill bit when using this and you shouldn't have any trouble drillingβ¦
Pros
1/4 in. hex shank - for use in quick change chucks
