I would recommend the Deep Freeze Quick Connect. It’s a nice system and I’ve converted several ION bits to be used with a drill.
On a side note, you can currently get a 8″ ION composite bit on clearance from ION Website for $79 add the $45 Deep Freeze adapter and you have a sweet “Pistol Bit” for only $125!
If you watch this video at the 1:00 mark, you can see how to adapt the Deep Freeze Quick Connect to the ION bit. (this was a 10″ version but same thing with 8″). Pretty sweet auger deal for only $125! https://www.youtube.com/watch?v=PF4MIKO05TQ&t=2s
