I was browsing through ebay and came across something that I’m sure I’ve never seen before and had to share it. It’s a drill chuck threaded for an angle grinder spindle, there’s a video of it here: https://www.youtube.com/watch?v=C2c4TsZ2rJc. I guess if you need a 11,000 rpm drill it might fit the bill. The best part of the video of him using it with a 2" hole saw.
