I'm working on a whole drill press built around mine...
I like the fact that my "regular" annular cutters with 3/4" Weldon shanks can be easily held with a 3/4" collet in the mill or in the drill press with the use of a MT/Weldon adapter.
Can the same be done with NK?

I finally got around to adapting a drill bit to my mag drill. I took a carbide-tipped annular cutter that was dulled beyond repair and cut off the shank. Drilled a 3/8" hole in said shank and held a stub of a 3/8" drill bit in with two set screws.
I've had occasion to use it and it works well. Now I just need to find a whole bunch more ruined annular cutters to make other sizes...
I think you can buy twist drills with 3/4” Weldon shanks.

I lugged a Milwaukee around more than I care to remember. Damm, it they are heavy. But they were the most common on job sites.

Excellent point! But I could not find any with Nitto Kohki proprietary quick-change shanks.
