works great with the 12″. When I bought the 12″ they didn’t have any 6″. with the 2 in combination I can negotiate a variety of conditions to drill with the Bosh panel bits. I’m drilling holes in studs for electrical wire runs.

Worked well when drilling 10″ into a cedar log with a 1-1/2″ spade bit. I did have to start with smaller bits and work up to the large size.

The chuck would not hold so I returned it for a new one. I’ve own dozens of these types of extensions and Bosch makes the best ones. I wear them out because of the impact driver. Use em 5 days a week. Last about a year.
