Some of the Sorby HSS and Carbide cutters do not fit the gooseneck hollowing bar I want to use. What method is used to enlarge these mounting holes? Will a regular drill ream the hole?

Just a WAG, but I think you’ll need a carbide bit. I have never had any luck trying to drill HSS with an HSS drill bit.

How much larger do you need to make them? If it is just a smidge, how about a dremel with a cone shaped grinding stone bit. You could also chuck the stone in a drill press for a little more control. For a carbide cutter, you would have to use a diamond one. If you have to enlarge the countersink, that could be another issue.

There is the answer I was looking for. Thank you. I had forgotten the Dremel diamongs.
