30mm Bracket for Drill Press

Love the drill press but I wanted to use a better and slightly more expensive drill than the one suggested. I saw complaints about the drill bits getting loose. Here is the drill that I suggest:

This particular drill has a 30mm diameter instead of a 24mm diameter requiring a larger bracket. I also did not like the ball on the handle so I designed a new one.

Enjoy.
